TheRON MURRAY, FASSEASSE International President

The rewards of being the best: freedom.

One of the most poignant images of american

history is a photograph taken in 1963 of Martin

Luther king delivering a speech before an

audience of hundreds of thousands of americans in our nation’s

capital, Washington, d.c. With a background of the Washington

Monument, the spellbound crowd is mirrored in the reflecting pond

which lies between the great spire and the Lincoln Memorial. The

sea of faces look up to king as he delivers his message of

freedom and of having a dream- a dream for all americans.

if you can find this historical image, look closely. More

precisely, look behind the crowd control fence, three rows back.

For there, unmistakably, is a plumber.

as americans, we are now being questioned as to just how

good we really are. are our schools up to snuff? are our cars

shoddy? do we really care?

The american society of sanitary engineering’s Professional

Qualifications Program and Product standards Program stand for

QuaLiTy above all else. our members stand for quality and our

manufacturers stand for quality. The asse seal or PQ

certification is emblematic of the finest achievement the bearer

can ascribe to. yes, america does build the finest. Look for the

asse label.

What does this mean to the backflow

tester, sprinkler fitter, plumber or pipe fitter?

The rewards of being the best: freedom.

Freedom to work in a profession we love

and be rewarded with being able to live the

american dream.

here at asse we are growing at an

astounding yet manageable pace. i have

pledged that for the next year we will stretch

our imaginations. our dreams and freedom

as craftsmen will be better for it. L

OFFICE HAPPENINGS

Perpetuating Momentum

i am energized for 2010 and pleased to

be associated with the Board of direc-

tors, led by international President Ron

Murray of Portland oregon. Ron has a

distinct focus and has enthusiastically

enlisted the energy of several new and

returning Board and committee

members to further the cause of asse

and perpetuate the momentum

generated by outgoing president

Rich Prospal.

as we settle into the new year, i feel that

the transition of my position is complete.

With the addition of our newest staff

member, yet to be named, we have a

fully capable staff in the Westlake, ohio

international office.

in 2010, asse staff will continue to

hone their skills in each respective area

of expertise while experiencing cross-

training of appropriate tasks. This helps

everyone’s ability to assist in the event of

someone’s extended absence from the

office.

There are four asse standards that

need to be moved into revision status.

These standards are: asse 1022-2003,

Performance Requirements for Backflow

Preventers for Beverage dispensing

equipment, asse 1032-2004, Perfor-

mance Requirements for dual check

valve Type Backflow Preventers for

carbonated Beverage dispensers, Post

Mix Type, asse 1056-2001, Perfor-

mance Requirements for spill Resistant

vacuum Breakers, and asse 1057-

2001, Performance Requirements for

Freeze Resistant sanitary yard hydrants

with Backflow Protection.

it would be beneficial to group 1022

and 1032 together since they both deal

with backflow prevention for beverage

dispensing equipment. Backflow, which

can cause contamination or pollution of

potable water in plumbing systems, is

one of the major concerns of this

society’s standards Program. in the case

of 1022 and 1032 devices, the preven-

tion of contamination and the backflow

of co2 gas into copper piping of potable

water systems, which can cause copper

carbonate poisoning, is especially

serious and must be protected against.

Thus, the need to review these two

standards for any technological updates

in the interest of public health and safety.

These two standards are similar in the

sense they both have two independently

acting check valves that are designed to

operate under intermittent or continuous

pressure conditions. one of the main

differences is that the asse standard

1022, Performance Requirements for

Backflow Preventers for Beverage

dispensing equipment, also has an

atmospheric vent located between the

two check valves giving a visual indica-

tion that the downstream check valve has

failed if the backpressure exceeds the

supply pressure. in either case, periodic

inspection and servicing of these devices

is essential.

asse standard 1056, Performance

Requirements for spill Resistant vacuum

Breakers, is now nearly nine-years-old

and needs to be reviewed for any

possible changes or updates in tech-

nology. This standard was developed

originally with indoor applications in mind

where the discharge of water had to be

solved each time the device was pressur-

ized. These devices are suitable for high

hazard applications but are limited to

backsiphonage protection and are not to

be used to protect against backpressure

type backflow.

The other standard up for revision is

asse 1057-2001, Performance Require-

ments for Freeze Resistant sanitary

yard hydrants with Backflow Protection.

This standard was developed to protect

Last year we completed multiple

technological operational changes. This

year, we will shift our focus to increasing

the use of online collaboration tools to

enhance working group and committee

member involvement in the standards

developing process. More information will

be presented at the Mid-year Meeting,

scheduled for april 15-17, 2010 at the

embassy suites in independence ohio.

one final note for this edition is to report

that the financial stability of the

association is intact and there are no

surprises noted on the horizon.

Good day to all.

the potable water supply from back-

flow and ground water contamination.

There have been five different types

of yard hydrants considered in this

standard for protection against backsi-

phonage and backpressure, along with

freeze protection.

considered for revision, along with all

the other stable of asse standards,

help to protect the health and safety of

the public. We are currently looking for

volunteers to sit on the working groups

for each of these four standards. if you

Bill ChapinCash Acme / Reliance Worldwide Legislative Conference Call Chair

Well, it’s the new year, so that means

the folks in california and vermont are

now buying plumbing products used for

conveying drinking water made with lead

free brass. From what i have heard, it

has been a mixed bag in regards to the

success that manufacturers have had in

getting good material and a good sup-

ply of that material. What has not been a

mixed bag is asse’s certification

program for certifying these products.

The program is in full swing and i can

honestly report that getting your products

listed has never been easier. Please call

kim haffey, asse Product Listing

coordinator, at the asse international

office if you need help showing

compliance to the laws or listings to

nsF-61 annex G.

have you ever tried to petition a

local or state water purveyor to change

their specifications? if you have, then you

can appreciate the hard work

being done throughout our industry to

gain acceptance of the 2009 asse

Backflow standards and the asse

Product Listing Program. i am sure that

i have seen some past articles in this

magazine about the industry calling for

one document with the most stringent

requirements for backflow prevention in

north america and how asse has deliv-

ered. now it is time to get the word out to

those who need to know that there is one

fine certification program out there that

is ansi accredited, requires devices be

certified to the latest editions of the stan-

dards and require manufacturers’ facili-

ties be routinely audited to ensure quality

control procedures are being followed.

“The presentations we have given have

been widely accepted, but it usually takes

more than one presentation to create

change” states Pete chapman, General

Manager – Backflow Prevention at

conbraco industries. “We have rounded

first base in quite a few states, but it is

important that folks understand that this

is the whole backflow community asking

for this program, not just manufacturers.”

While we typically do not cover model

building codes in this section, there have

been several states already adopting

2009 editions of these codes. as you

know, when that happens it becomes

the law and thus newsworthy here. The

international code council has been

busy getting their 2009 codes adopted

in several states. The 2009 international

Residential code, as adopted by

california, Pennsylvania, new Jersey

and new hampshire, includes fire sprin-

kler requirements for new construction of

one and two-family homes and

townhouses.

one item to look for in a state near you

is the new Green Plumbing & Mechani-

cal code supplement that has been

published by iaPMo. This supplement

serves as a complement to any adopted

plumbing or mechanical code. if you are

looking for requirements for grey water,

rainwater harvesting or “high-efficiency”

plumbing products, this document was

designed to address it.

as you will be able to tell from the length

of this article, it was fairly quiet legisla-

tively speaking. i trust that this was due

to the holidays and not all the attention

on health care. you would have also

assumed that our group would have had

plenty of time to discuss the date and

time of our next conference call. Well,

according to the minutes it completely

slipped my mind. The next Legislative

conference call will be held on

Tuesday, May 4, 2010 at 2:00 PM esT.

if you would like an invitation to this

meeting, send a quick email to me

([email protected]) or Ben Ryan

([email protected]). our meetings

are conducted with Webex, so you must

get the invitation with the proper link and

access code.

WATCHBACKFLOW INDUSTRY

Sean Cleary, IPP, Region 7 DirectorIAPMO Field Manager

i thought i would start my first column with a controversial

subject. i want to be upfront about my background. i am a

Licensed Master Plumber and have been since 1988. i am a

member of the united association and have been an instructor

in my Local union’s apprenticeship and Journeyman Train-

ing Program for the last 16 years. i have been testing, install-

ing and repairing backflow prevention assemblies for the last

twenty years. over the years i have installed or repaired

hundreds of backflow preventers and tested thousands.

during that time, i have looked at countless numbers of incor-

rect and at times dangerous installations. The common thread

i have found with most incorrect installations is that the installer

ignored or had no knowledge of the installation requirements

mandated in the plumbing code and of the manufacturer’s

instructions and installation requirements. From isolation

protection installed in ceilings to reduced pressure backflow

prevention assemblies being installed in meter vaults, both

water purveyors and code inspectors seem to be unable or

unwilling to mandate installation requirements.

Too many people look at the backflow prevention assembly

or device as both the beginning and the end of the situation.

nothing could be farther from the truth. Backflow prevention

is a critical part of the system on which it is installed. if we are

looking at a plumbing, fire sprinkler or irrigation piping system,

the tester, repairer or installer must understand the installation

requirements, the system hydraulics and potential problems

that may arise as a result of the addition of backflow protection

to the system. Testing a backflow prevention assembly is much

more than differential pressure readings and spring tensions.

Looking across the spectrum of backflow tester certification

programs currently in use across the industry and the people

attending this training, we can see the different categories of

individuals receiving certification. These include plumbers,

pipefitters, sprinkler fitters, hvac service people, utility person-

nel, irrigation contactors and their employees, plant mainte-

nance personnel, and others who see an opportunity for future

employment or business. Most certification programs have

minimal prerequisite requirements for enrollment. The require-

ment is usually a high school diploma or a Ged certificate.

Backflow tester certification programs provide the basics in

training to an individual. however, the attendance and comple-

tion of a thirty two to forty hour class of instruction in no way

prepares an individual to enter the field and begin testing,

repairing or installing these critical components within our

potable water systems. (Continued on page 27)

Yes, I Said It. People Who Test, Repair and Install Backflow

Preventers Should be Licensed Plumbers

The World Plumbing council created World Plumbing Day to be celebrated on

March 11th every year … everywhere. This year, the inaugural event will be

announced at a press conference in Beijing, china on March 11 as a part of ish

china 2010.

The american society of sanitary

engineering has been a member

organization of the World Plumbing

council since its inception and many of

asse’s members have served as officers

and board members of the WPc over the

past many years. asse has played an

integral part in the development of the

council’s objectives and in the creation of

World Plumbing day.

This annual event has been established

to help the general public better under-

stand the vital role that the plumbing

industry plays in protecting public health

and safety, and understand the extent to

which the plumbing industry helps limit

mankind’s environmental footprint. This

day also acknowledges other important

work being performed by contractors,

inspectors, installers, engineers, manu-

facturers and academicians that is often

taken for granted.

We know that this announcement gives

short notice for any very special activities

to happen this year, but we will do what

we can with the time that we have. We

then must continue with thoughts and

ideas for next year and continue develop-

ing these ideas into the future. it’s about

time that a concerted effort is made to

raise awareness of the important role that

plumbing plays in everyone’s everyday

lives. it has been said many times that

the advent of safe plumbing practices,

which deliver clean drinking water and

dispose of sewer product, have contrib-

uted more to public health than all of the

doctors and medicines in the world. safe

plumbing practices have reduced the

number of deaths and illnesses caused

by water borne diseases, thus

creating a better quality of life for the

world’s population.

We would like to see World Plumbing

day used to promote the fact that plumb-

ing tradespersons are professionals and

that these professionals have the utmost

importance in protecting the environment

and public health.

as a means of promoting World Plumb-

ing day around the world, the WPc has

developed a website at: http://www.

worldplumbingday.org. The information

on the website has been designed so

that the featured materials can be repro-

duced, amended, supplemented – basi-

cally anything one can do to promote this

day on their own – as we lead up to the

11th day of March each year. asse and

the WPc welcome and encourage any-

one to use the information on the website

to help promote this day.

The World Plumbing day website fea-

tures two fact-sheets that have been

developed by the WPc. The first covers

the “health aspects of Plumbing,” which

is excerpted from a publication that the

WPc wrote and published in conjunc-

tion with the World health organization.

The second, which centers around the

“environmental aspects of Plumbing,” is

a work in progress and is expected to be

completed this year. Please visit the web-

site to read these interesting fact-sheets.

in december 2009, WPc chairman,

Robert Burgon of scotland, spoke to

a classroom of eight-year-old school

children in east Lothian, scotland to

invite them to design posters about the

health aspects of plumbing. Burgon had

been invited to the school to support the

work being done on the health related

issues of water. during his presentation,

he mentioned World Plumbing day and

asked the 90 pupils to develop a poster

that could promote the day.

Burgon chose five “winning” posters out

of the 90 submitted and the successful

pupils were presented with certificates,

books and posters. “it was really encour-

aging to see the results of this exercise,”

Burgon commented. “Many of the pupils

had clearly listened carefully to the short

presentation i made. There was an

interesting range of images used, rang-

ing from the most famous plumber in the

world (super Mario) to quite strong mes-

sages about the health dangers of dirty

water. i think that these children all really

understand the important link between

water, sanitation, health and the plumb-

ing industry.”

World Plumbing day is all about raising awareness of the important role that our plumbing industry plays every day … everywhere.

Reclaimed Water:Sources and Treatment Methods

The demand for green construction, coupled with local and regional water shortages around the USA, have pushed water conservation to the forefront of many people’s minds. Of course, this typically involves mandating low-consumption fixtures, choosing climatically-suitable landscaping, enforcing watering bans, improving leak detection methods and improving people’s habits through a combination of price incen-tives and education. The next step, however, is to reclaim and reuse the various wastewaters collected/generated within a facility or community. Water reclamation can be utilized to further reduce consumption or to simply ‘soften the blow’ of water conservation mandates by providing a plentiful alternative source.

While a small number of individuals are reclaiming water as a potable source (primarily on the residential level), the vast majority of applica-tions are very smartly supplying non-potable systems, such as irrigation, cooling system/boiler makeup, fixture flushing, vehicle washing, munici-pal washdown or industrial process. Though these applications are non-potable, an astute architect, engineer, contractor or facilities manager will always be mindful of the potential for cross-connections or other situations which could lead to accidental aspiration or consumption of reclaimed water. Put simply, it is critical to examine the potential health hazards of both the source of water being reclaimed and the application in which it is being used.

The greatest buzz of course revolves around rainwater harvesting. In principle, rainwater provides an extremely clean and (in some areas) abundant source of water. Potential risks, however, include leaching roof materials, infestations of microorganisms such as Salmonella, E. coli, Cryptosporidium and Giardia (all potentially present in bird feces), and the usual mold, algae, slime, scum, discoloration and odor that is typically present any time a supply of water sits stagnant in a tank.Another very viable source, depending on local humidity levels, is condensate collected from air conditioners and chiller systems. In many applications, this can amount to thousands of gallons of water each year – so much that certain US cities are beginning to mandate its collection and reuse. The primary pitfalls of condensate reclamation include bacte-riological contamination, such as Legionella, and mold from condenser coils. Users must also be mindful of pH levels when choosing system/piping materials (condensate can be quite acidic).

A third source, very popular in states like California, is on-site collected graywater from lavatories, showers, laundry, etc… When used for sub-surface irrigation, the health risk is quite low (simple filtration usually suffices), though a study of potential soil impact should be run prior to the installation of any system. However, if used for flushing fixtures or any other application, one must go to great lengths to ensure the proper disinfection and treatment of graywater. The potential for contamina-tion by human, animal, or food waste – and other substances – is very real!

Other potential sources include, but are not limited to, groundwater from French drain (aka “drain tile”) systems, cooling tower blowdown, RO/DI concentrate and industrial effluent. When any of these sources are involved, samples of the specific water to be reclaimed must be tested for any substances posing a risk to public health or to the systems they are feeding. Groundwater may contain elevated levels of calcium, iron, manganese, VOC’s, etc… Blowdown and concentrate can be very challenging due to high concentrations of salts, fluoride, chlorides, cal-cium, or whatever else was in the water originally feeding the system. Of course, industrial effluent is always a wild card.

Some applications, such as subsurface irrigation, do not require disin-fection. However, in most cases it is highly advisable to have systems and monitors in place, particularly if the application is commercial or institutional in nature. While other methods exist, the three most com-monly employed techniques for on-site reclaimed water disinfection are: Ozonation, ultraviolet treatment and chemical injection.

Ozonation involves recirculating and injecting, or sparging (diffus-ing) ozone gas (o3) into a tank of stored water. A huge advantage to this method is the fact that ozone is generated on-site and requires no chemical delivery or storage – all that is required is a small amount of air and electricity. Ozone is an oxidizer, much like chlorine or hydrogen per-oxide, except the speed at which it breaks down organic matter is literally thousands of times faster (virtually instantaneous). Typically, ozone will revert back to o2 within 10 to 20 minutes, depending on water purity levels. This is an advantage in the fact that there are very few harmful residuals. It is also a disadvantage in that it provides no long-term re-sidual disinfectant; often times, a small amount of sodium hypochlorite is added prior to delivery of the reclaimed water.

Ultraviolet treatment involves flowing reclaimed water through a hous-ing containing a water-tight bulb that emits high levels of UVC radiation at the 254 nanometer wavelength. Provided the bulb is not dirty and the water is transparent (i.e. not turbid), UV treatment is highly effective in deactivating a multitude of bacteria, viruses and other organisms. It does so by literally destroying DNA fibers. Like ozone, UV treatment has the advantage of requiring no on-site chemicals; however, it provides abso-lutely no residual disinfectant. Pre-UV filtration is an absolute must in order to reduce turbidity. A good system will incorporate tank recircula-tion to limit tank growth, final pass UV treatment (just prior to delivery) and monitor UV light intensity inside the housing to ensure that a bad bulb, bioslime or turbidity is not inhibiting proper disinfection.

Chemical treatment in a commercial application will usually consist of tank recirculation and the monitored/calibrated injection of sodium hypochlorite or chlorine dioxide solution to maintain adequate tank disinfection levels. These systems can be controlled by Cl or ORP sen-sors in the tank or recirculation piping. Simply injecting a low dose of chemical prior to the delivery of reclaimed water will usually not suffice, as this does not provide for adequate contact time to achieve disinfec-tion. Both of these chemical oxidizers have the disadvantages of chemi-cal storage, handling, delivery and ongoing purchase. In regards to these issues, chlorine dioxide is usually a better option, as it can be generated on-site via the mixture of two relatively benign compounds, both with a much longer shelf life than the 12% sodium hypochlorite often used for swimming pools. Chlorine dioxide is also more effective on algae and is a much faster oxidizer. In addition, it provides a longer-lasting residual disinfectant, which makes it great for applications like graywater reclamation.

The bottom line: Whenever one is working on a water reclamation proj-ect, particularly if it involves a commercial or institutional application, it is critical to examine the risks of chemical and biological contamination, coupled with the potential for inadvertent human consumption/ aspira-tion. A good system will include proper filtration, disinfection, monitor-ing, and fail-safe systems to mitigate these risks. This will go a long way in protecting human health and eliminating unnecessary liabilities.

requiring minimal interference and maximum precision and accuracy; atomic absorption, flame emis-sion spectrometry, ligand assays, trace metals, enzymatic procedures sensitive to trace metals, electro-phoretic procedures, high-sensitiv-ity chromatographic procedures, fluorometric procedures, buffer solutions and standard solutions.

Type II Water Type II water is for test methods

that can tolerate the presence of bacteria; general reagents with-out preservatives and microbiol-ogy systems (not to be sterilized). Also for test methods not requir-ing Type I or Special Purpose wa-ters; stains and dyes for histology, general reagents with preservatives, and microbiology systems (to be sterilized).

Type III Water Type III water is for general

washing, feedwater for produc-ing higher-grade water, as well as bacteriological media preparation.

Special Purpose WaterSpecial Purpose water is for

procedures requiring the absence of specific contaminants: pyrogens for tissue/cell cultures or trace organics for high performance liquid chromatography (HPLC).

PURIfICATION METHODSNo single water purification

method is suitable for all labora-tory applications, which is why commercial purification systems often combine techniques. Below are some of the strengths and limitations of the eight purification methods to help specify the combi-nation you need.

Distillation Distillation has several positive

features. The equipment is rela-tively inexpensive, there are no expendable parts other than re-placement glassware and heating elements, and it generally produces water of good quality. Distillation typically produces water of Type II or III quality, with a resistivity of about 1.0 megohm-cm.However, distillation has

several drawbacks. Because of these, it is not as widely used as in the past. Because distillation is not an on-demand process, a quantity of water must be distilled and stored for later use. If the storage container is not made of an inert material, ions or plasticiz-ers will leach out and re-contami-nate the water. Bacteria are known to grow well in standing water. The bottles may be sterilized and the collected water autoclaved, however, once a bottle is opened, it is exposed to bacteria and contamination begins.

When designing a pure water system, the plumbing engineer is often faced with the task of determining which type of system should be specified. In order to design and specify the proper system, the designer must first determine which type of water is required. After the type of water is determined, the designer chooses the piping material and does a piping layout to minimize the dead legs or branches with no circulation in the piping system.

Distillation has other drawbacks as well, including being highly wasteful of energy and water; typi-cally only 5% of the water used in the process ends up as product water. Stills require regular cleaning due to a buildup of mineral depos-its from the feedwater.

Deionization Deionization is a commonly

used method in laboratories for producing purified water on demand. Deionization functions by exchanging hydrogen ions for cationic contaminants and hy-droxyl ions for anionic contami-nants in the feedwater. The ion exchange beads are tiny spherically shaped gels through which the feedwater passes. After a period of time, contaminating cations and anions will replace all the active hydrogen and hydroxyl groups in the beads and the cartridges will need to be replaced or regenerated. Deionization has many advan-

tages over distillation for the production of purified water. First of all, it is an on-demand process. Secondly, when using nuclear grade resins, almost all the ionic material will be removed from the water to a maximum resistivity of 18.3 megohms-cm (at 25°C).Deionization has certain draw-

backs though. Tiny fragments of the ion exchange resin material can be washed out of the system by the water passing through it. Also, stagnant water in cartridg-es may allow excessive bacterial growth. Thirdly, deionization will not remove dissolved organ-ics from the feedwater; in fact, dissolved organics can foul the ion exchange beads. Finally,

Deionization cartridges can be an expensive option for labs that choose to replace their cartridges rather than regenerate them.

Reverse Osmosis Reverse Osmosis, or “RO”, is a

process that overcomes many of the shortcomings of distillation and deionization. To understand reverse osmosis, you need to recall the natural process of osmosis. Osmosis is the movement of wa-ter across a semipermeable mem-brane from a less concentrated (purer) side to a more concentrated (saltier) side. This movement continues until the concentrations equilibrate or the pressure on the more concentrated side becomes large enough to stop the flow.If a pressure greater than the

osmotic pressure is applied to the more concentrated solution, such as with a high-pressure pump, then water molecules will be pushed back across the membrane to the less concentrated side, making the more concentrated solution even more concentrated. This is the process of reverse osmosis.Reverse osmosis typically

removes 90-99% of all contami-nants. Because of this excep-tional purifying efficiency, reverse osmosis is a very cost-effective technology for a water purification system. Reverse osmosis tends to protect the polishing system from bacteria and pyrogens and is often combined with ion exchange to significantly prolong the life of the deionization cartridges. A system that dispenses RO water provides high quality, pre-purified water that is suitable for many routine laboratory purposes.

Activated Carbon filtrationActivated carbon filters re-

move chlorine by absorption and dissolved organics by adsorption and are often found at two places in a water purification system. Because thin-film composite RO membranes are sensitive to chlo-rine and, to a lesser degree, fouling from dissolved organics, activated carbon is often placed prior to the RO membrane to remove these contaminants.A granular activated carbon

filter is often placed in the polish-ing loop of a water purification system to remove trace amounts of dissolved organics for a water quality suitable for HPLC work.

Microporous filtration Micro filtration uses a membrane

or hollow fiber with an abso-lute pore size of 0.2 microns that prevents any contaminants larger than 0.2 microns from passing through it. Many smaller particles are trapped through the process of electrostatic attraction. These include carbon fines from the organic scavenger cartridge, resin fragments from the deionization cartridges and bacteria that may have entered the system. CAP and NCCLS Type I water is considered to be particulate-free when it has been passed through a 0.2 micron filter.A microporous membrane is

generally considered to be an indispensable element of a water purification system, except when superseded by an ultrafilter.

Ultrafiltration Ultrafiltration uses a membrane very similar in design to reverse osmosis systems, except the ultrafilter’s pores are slightly larger.Since a high percentage of the

water that is brought to the ultra-filter passes through, the ultrafilter will eventually clog up if it is not maintained. In a well-designed system, the ultrafilter will be tangentially washed free of contam-inant buildup on a regular sched-ule. With this design, ultrafiltration is an outstanding technology for insuring very consistent ultrapure water quality.

Ultraviolet or Photo Oxidation Ultraviolet, or photo oxidation,

uses ultraviolet radiation at the biocidal wavelength of 254 nano-meters to eliminate bacteria from a system and to cleave and ionize certain organics for subsequent removal by the deionization and organic adsorption cartridges in the polishing loop.

Electrodialysis (ED) Electrodialysis removes impuri-

ties from water using an electrical current to draw ionic contaminants through ion selective membranes (ion exchange resin in sheet form) and away from the purified water. When occasionally used to produce potable water from clean brackish feedwater, ED is cost competitive with reverse osmosis.In producing laboratory-grade

water, however, ED has several drawbacks and is rarely used in lab settings. First, the contami-nants that ED can remove are limited. ED cannot remove certain organics, pyrogens and elemental metals that have weak or non-existent surface charges because they are not attracted to the mem-branes. Secondly, ED requires a skilled operator and routine main-tenance. Large molecules bearing a significant charge, such as certain colloids and detergents, can plug the membrane’s pores, reduc-ing its ionic transport ability and requiring frequent cleaning.

During operation, ED liber-ates caustic soda, which may cause scaling, and hydrogen gas, which is potentially dangerous. Finally, ED is relatively expen-sive. As ionic contaminants are removed from the water, its electrical resistance increases so that higher electrical current is required to continue the purifica-tion process. Purification beyond the potable level is considered uneconomical due to increased electrical consumption. Compo-nent materials such as platinum and stainless steel are expensive too.

PIPINg CONSIDERATIONS Piping materials for high purity

water systems have to take into consideration the intended use of the water. High purity water systems are typically made from Stainless steel type 316 (S/S 316), Polypropylene (PP) or Polyvinyli-dene Fluoride (PVDF). There have been occasions when lower quality water systems allowed the use of Polyvinyl Chloride (PVC) or Chlo-rinated Polyvinyl Chloride (CPVC). Usually PVC & CPVC piping is not used in high purity piping systems because they can leach out anti-oxidants, pigments or other contaminants.

POLISHINgPolishing is the process of

recirculating the pure water back into the treatment system using one or more of the purification methods described previously. The reason for polishing, or recir-culation, is to continually remove contaminents because pure water is very aggressive and will dissolve contaminants from the piping material to a small degree. If the water is allowed to stand in a dead end branch for extended periods of time, there can be bacteria growth and other contaminants dissolved into the water. For labs that require ultra pure or very high purity water systems, a stainless steel or plastic recirculation pump can be used to circulate the water through the

branch piping to keep the purity of the water at a high level. In the microchip processing industry, impurities in rinse water can cause shorts in microscopic circuits on printed circuit boards. Therefore, ultra-pure water is very important in this industry.Manufacturers now offer

special plastic or plastic lined lab faucets that can handle the high purity water without leaching brass into the water. Some manufactur-ers have faucets that allow the recirculated water to travel all the way to the tip of the faucet. Each high purity recirculated lab faucet has a supply and a return water connection.

IN SUMMARy, the plumbing engineer must determine the type of water that is needed and design a purification system that balances the water quality desired with the associated costs for the system. When all of the first cost and operating costs are investigated, it is prudent to design and specify the level of purity that matches the application. Generally, the more pure the water is, the more expen-sive the system is. Matching the system to the application can save your client money.

NEW YORK CHAPTER


Three words that best describe the asse new york chapter are dedication, commitment and action. The past history speaks for itself. established in 1947, we have been privileged to have many of our industry’s “who’s who” seated in leadership roles, including seven elected international Past Presidents and eleven recipients of the prestigious henry B. davis award. The new york chapter has also won the dewey R. dedrick Jr. award nine times for overall performance. We are fortunate to have many of the new york chapter’s former presidents, such as Joe Petro (1970) and Pat McGarvie (1982) who are happily retired but still lurk about in the shadows ready to lend support. Their dedication has made high standards the norm and we have other no choice but to maintain the standards that they set during their tenures as president. serving currently on our cur-rent chapter Board is international Past President Bob zeuner (1990) as Treasur-er. Bob wears many hats as he “referees” our Board meetings and serves as an invaluable liaison officer, both locally and nationally. Tom diPietro (1983) is our newsletter editor. Tom has made phe-nomenal strides in reviving the chapter newsletter and evolving it into what it is today: better than ever. Many members, in addition to their regular schedules, teach plumbing design courses at nyu, st. John’s university and the Mechanics institute, to name a few. our chapter also remains committed to serving on various national committees, such as the seal control Board, By-Laws committee, Product standards committee and code committee.

The society has experienced its ebbs and flows throughout the years, how-ever, good things happen even in tough times. With many people out of work, our chapter felt it was our duty to serve our members in whatever way we could. With the chapter suffering its own financial struggles, we recommitted to find our

purpose and get busy for both the sake of our members and the longevity of the chapter.

about five years ago, due to struggling attendance and financial concerns for both the local chapters of asse and asPe, we joined forces to have joint meetings. While we maintain separate identities, we share the same goals in serving our members. as a result of our combined efforts, we have vastly improved the quality of our technical seminars and the proof is in our increas-ing attendance. We have gotten over 100 people to attend, but average about 65-70 attendees. There is no charge to attend and everyone is welcome. our joint objective is to build a foundation and keep raising the bar on technical presen-tations. To serve our young attendees, we provide presentation topics on the essential fundamentals. We also provide interesting presentation topics that may not necessary be related to most members in this region, but are innova-tive subjects that are far from conven-tional. on a typical evening, we will have a social hour that includes a buffet dinner and a tabletop display with products and ample literature provided by our sponsor. We email our monthly newsletters out to our members, but we also have many copies available at the meetings.

Back in september, we had an up close look at corrosion analysis of piping. our speaker, Robert crosson, Pe, gave a fascinating presentation on the forensics of water piping corrosion. in october, Mr. Jack Rosenberg spoke about marine plumbing and Fire Protection systems for ships. For the nyc community, this was a breath of fresh air for the many who predominately design office towers. We closed the year in november when Mr. Warren Liebold of the department of environmental Protection spoke about what’s new for water metering in nyc. as we move into 2010, we have our calendar nearly full with some terrific speakers and sponsors. our March

meeting will consist of a panel discus-sion, which we feel will be the highlight of the year. The panel will have an engineer on the code committee, a manufacture representative, a contractor on the code committee and our own department of Buildings representatives discussing the new Fire code. This is what it takes to keep our members engaged.

The new york chapter had the fortune of electing a very capable chapter past president, John callaghan (2005-2006) with callaghan Pumps of hackensack, nJ. John won the annual Meeting asse scholarship Fund’s 50/50 Raffle back in november and showing his heart of gold, donated the entire winnings to our schol-arship fund. With his generous donation, we can invest in our youth to provide a future for our industry.

our goal is to build our future today. The asse new york chapter is aligned to remain loyal to the cause “Prevention Rather Than cure,” increase our membership and build our future today by providing academic scholarships to various local institutions in the Big apple. We see that it is essential to maintain high standards for tomorrow’s plumbing industry.

High Purity Water Utilizationby Steve Silber, ASSE International 3rd Vice President

Due to the variety of ways water is used, there are many different levels of purification required by end users. Currently, adopted plumbing code requires potable water to be tasteless, odorless and clear. Two of the most commonly used methods of purifying water beyond the require-ments needed for potable water, are filtration and reverse osmosis. Filtration uses a sediment filter to trap particles such as rust and calcium carbonate. When using the reverse osmosis method to further purify water, an active carbon filter is installed in the filter chain to protect the membrane used in the process. Using an active carbon filter will trap im-purities such as chlorine and other organic chemicals that can harm the membrane. Water purified by the reverse osmosis process is often used to further purify a potable water source for drinking water purposes.

Another method used to purify water beyond the requirements of potable water standards is the deionization process. Deionized water is so pure that it contains no trace minerals or other elements. This water will actually absorb minerals and other elements from materials and surfaces it comes into contact with. Deionized water is slightly corrosive for this reason and it should not be introduced to the human body for consumption.

There are many uses for deionized water in industry and product manufacturing operations. For example, mineral deposits can prevent proper heat exchange action in boilers. Deionized water is often used for incoming feed water to high pressure boilers in order to prevent the buildup of minerals and deposits on the inside of the heat tubes. Deionized water is also widely used in the electronics and semiconduc-tor industries because of its high level of purity and because it has the inherent properties of being non-conductive and slightly corrosive.

High Purity Water and Ultrapure Water are terms and/or specifications used to describe increased levels of purification of deionized water.

Purified water is used in the pharmaceutical, chemical manufacturing and cosmetic fields. The purified water process includes the reduction of microorganisms as well as minerals.

Apyrogenic water is a term used to describe what is commonly known within the biopharmaceutical industry as water for injection, or WFI. WFI is used to manufacture medicines, vaccines and other substances that can or will be introduced into the human body. Filtration and distil-lation processes are used when manufacturing WFI in order to remove specific levels of contaminants from source water. Contaminants that must be removed in order to manufacture WFI are referred to as par-ticulates, minerals, chemicals and organic bacteria.

In conclusion, the ASSE Series 11000, Professional Qualifications Standard for High Purity Water Systems Installers, is a critical piece of the installation process. Without standards, the medical industries and manufacturers would not know what is coming out of the source pipe being used.

Conducting Plumbing Energy Surveys:

Potential energy savings in Plumbing systems

pipe runs and sizes, and the greater amount of hot water stored, the greater the opportunity for energy savings.

Hot Water Temperature: Some energy codes and standards for new buildings require system temperatures to be set at 110°F. In many instances the buildings are operating at temperatures in the 160°F to 200°F range which require a temperature study. Temperature reduction should not be done on an existing building without analyzing the necessary operating hot water temperatures at the various fixtures and appliances and reviewing the heater capacity. Many buildings can safely operate at a temperature of 140°F at the heater outlet and 130°F on the return line to the heater. Temperatures below this range should be carefully analyzed to avoid the possibility of Legionella. If the system temperatures can be reduced without altera-tion to the system, then nominal savings can be achieved without any capital investment. If any alterations in the piping system or the heater are required, the payback period will probably be too long. The energy savings are determined by comparing the surface losses of the present circulated piping system and heaters with the surface losses in the proposed system. Like time clock controls, pipe lengths and sizes, storage and high initial temperatures are factors for effective savings and reasonable payback periods.

In evaluating the possibility of temperature reduction, actual hot water temperatures should be recorded at the fixtures and heater outlets. If the building has a storage heater, the adequacy of hot water in the present system

In recent years, the high cost of construction financing and the increase in energy costs have discouraged new building construction and have highlighted the need for energy conserva-tion. Many engineering and contracting firms, faced with the challenge of preparing retrofit studies and designs to save energy, must care-fully calculate building energy requirements.

Calculations should consider actual building use instead of theoretical design methods. The most accurate way to determine building energy is to study building operations in the field. Many people believe that the major savings are in the HVAC, lighting and build-ing construction features. Although this may generally be true, the potential energy savings in plumbing systems should not be overlooked.

Possible energy savings opportunities are known in the industry as Energy Conservation Measures (ECMs). These are evaluated finan-cially by simple payback periods which do not reflect interest costs or inflation. To determine the payback period, the construction cost due to a potential ECM is divided by the annual energy savings of the ECM. Five years or less is generally considered reasonable and may be recommended. However, this may vary with each owner since he may have his own criteria regarding payback requirements.

In conducting an energy survey of a building’s plumbing systems, the following steps should be pursued:

General Survey: The First Step is to perform a building survey. Existing plans must be verified since they tend to be outdated; fixtures shown on plans may have been removed or shut-off, or new fixtures may have been added. The actual use of plumbing fixtures should be discussed with the operating personnel. For example, in shower rooms, the number of people taking showers and the showering periods should be determined. In some instances, showers may not be in use at all and the rooms may actually be used as storage spaces.

Building Occupancy: During the survey, the number of people in the building should be verified along with the number of days occupied, the hours of operation per shift and the number of persons per shift. Obviously the occupancy will reflect the energy savings potential.

Time Clock Controls: Buildings such as office buildings with one shift a day, five days a week can especially benefit from the addition of time clock controls for the domestic hot water system. The time controls are designed to shut off the domestic hot water system during periods when buildings are unoccupied. The weekday shut-down period usually lasts from the time the cleaning personnel leave until about one hour prior to occupancy in the morning. On weekends and holidays, the hot water system is programmed to shut down for longer periods. The energy savings are from the reduced surface heat losses of the circulated piping system and water heater. When time clocks are installed, the greater the length of

3 GPM to about 18 GPM for showers. This occurs mostly in older buildings where the fixture supply fittings are not up to the current industry standards. Naturally, fixture usage is throttled to some extent, although single lever fixture controls (especially showers) tend to be used at almost full open. Average fixture flows at blended temperatures should be measured at lavatories and shower heads. Filling type fixtures, such as bathtubs, janitor’s sinks (to fill a cart or bucket) or kitchen sinks, need not be considered for flow reduction. Flow rates can be determined by using a measured 1 gallon open top jug and timing the filling period. For showers, the jug opening should fit over the head and for lavatories, a funnel and hose need to extended to the jug.

Fixture flow rates can be reduced by providing devices to control the flow or by replacing the fixture supply. The two basic types are auto-matic flow control fittings and flow restrictors. The auto flow control has a pressure compen-sated orifice. The American Society of Sanitary Engineering’s Product Standards Committee has worked on separate standards for these devices.

The location of the flow devices and the method of installation will affect the retrofit costs. On lavatories, the type of faucets (combination, centerset or individual faucets)and the spout features, combination or plain end, will dictate the quantity and location of the devices. With plain end spouts, the device must be located in each of the piping supplies and requires a significant amount of labor. With aerator or threaded spouts, the flow control device can be added in place of the aerator at nominal labor costs. In showers, the type of head (threaded to the arm or wall mounted without an arm ) will be a factor in the flow device location and the retrofit costs. The most favorable and common type of shower arrangement is the threaded arm, where the flow device can be inserted between the shower head and the arm at a nominal cost. In many instances, it may be easier to provide a low flow shower head replacement. On insti-tutional wall mounted heads, the pipe nipple in the wall must be shortened to accommodate the flow control fitting and this adjustment requires more labor.

Flow rates for flow control devices must be carefully selected in existing buildings after the hot water distribution system is analyzed. On lavatory fixtures, unless the dead leg is reason-ably short, too low of a flow rate creates an unreasonable waiting period for hot water. New building agency and code requirements of 0.5 GPM flow devices on lavatories can be misleading and unsuitable for retrofit buildings.

should be reviewed. Reducing the domestic hot water supply temperatures will also reduce the water heater storage capacity. A system analysis must be performed to determine the feasibil-ity of system temperature reductions. If the building is provided with a kitchen dishwasher, then the booster may not have adequate capacity to properly function at the increased delta temperature due to the reduction of the building system temperature. Replacing or supplementing the booster heater is usually not cost effective.

Hot Water Service Equipment: Commercial dishwashers and laundry machines use large quantities of hot water and have potential energy conservation features. An important feature of dishwashers is the pressure regulating valve. Is one provided and what is the pressure setting? Most dishwasher manufacturers recommend 20 psi on the booster hot water inlet connection to the dish-washer. At high pressures, the rinse consump-tion is increased necessitating properly set pres-sure reducing valves. On commercial laundry equipment, heat reclamation of the rinse water waste offers energy saving large enough to consider reclamation equipment. Heat recovery for domestic use from steam condensate and other related HVAC systems are possible considerations, but are too complex to include in this article.

Summer Hot Water:Summer hot water usage for domestic water heaters supplied by steam or hot water from main boilers should be analyzed. This occurrence happens in many schools with summer sports programs. Where boilers

designed for heating large buildings are used during the summer to heat only nominal domestic hot water loads, they generally operate at low efficiency. Comparing the oil or gas consumed with the domestic hot water usage during the non-heating season is the basis for determining the boiler seasonal efficient. Comparatively small domestic water heaters using oil or gas could be provided to permit the shutdown of the main boilers during the season. The present chimney or boiler breeching can be utilized if necessary precautions, such as electrical interlocks, are provided on the boiler burners to prevent simultaneous operation with the new heater. Where the present water heater is provided with storage, the heater size can be minimized by circulating the heated water through the storage tank.

Insulation:In energy surveys, the lack of insulation on the hot water piping systems and water heaters will suggest and ECM. Adding insulation to uninsulated piping and tanks can usually be done within a reasonable payback period.

Fixture Flow Reduction:Fixture flow rates vary with the supply fitting design and the water pressure. Fixture flow reduction is feasible in older buildings where fixture supply fittings have not yet been upgraded to current industry standards. Manufacturers’ test results show that flows can be quite high at lavatories and showers, the prime candidates for fixture flow reduc-tion. Unrestricted flows at water pressures of 45 to 80 psi can range from about 2.5 GPM to as high as 19 GPM for lavatories and from

Flow is based upon 50° cold water inlet and 105° outlet temperature at 45 psi water pressure. Fc denotes automatic flow control device. in the above table, note that the proportion of hot water increases at lower temperatures. This does not affect the Btu’s at the fixture outlet but will affect the hot water storage capacity of the storage heater.


For showers, a reduced flow rate of 2.5 GPM is the national standard flow requirement.

For computing annual hot water loads for present and reduced flows, the full population use must be taken into consideration. For lavatories, this calculation should also include the number of daily uses per person, the washing period and the flow rate. For showers, this calculation should include the number of uses per week, the showering period and the flow rate.

At specified fixture flow rates and constant outlet temperature, the ratio of hot to cold water varies according to hot water system temperature. The Fixture Flow Table (figure 1) illustrates the percentages of hot water at the various temperatures.

Maintenance and Operation: The building operating personnel should be questioned to determine if any energy conservation measures are being implemented or proposed. Maintenance practices and problems of the domestic hot water systems should be discussed. A careful building survey can disclose worthwhile savings at nominal

costs. For example, on water heaters, defective relief valves, leaking manhole gaskets, leaking tanks and missing portions of insulation are common problems. These defects are especially likely to be overlooked in campus type building complexes where maintenance staff is mini-mal and the heaters are in remote locations. A typical example I have encountered is a remote heater installation where the relief valve was discharging 200°F water at the rate of 2 GPM for an unknown time period. Not only is this wasteful, but the temperatures are dangerous to the building occupants. Another example is a steam storage type heater which was leaking approximately 15 GPM of 140°F water for at least three to four months. The heater replace-ment costs were minor in comparison to the energy savings.

In conclusion, a building must be completely surveyed and its usage carefully analyzed in or-der to prepare proper energy calculations that will lead to useful energy audits. Calculations should be conservative because of human hab-its. It is better to underestimate savings than to mislead a client into believing he will achieve higher theoretical savings.

apollo® valves earned a reputation for developing new products to meet emerging market demands. in 1968, the company introduced its apollo® series 70 ball valve to the commercial market, a revolutionary innovation at the time.

conbraco industries got its start when two detroit based brass manufacturing companies combined forces in 1928. The name conbraco is an acronym for Consolidated Brass Company. under the leadership of company founder clarence Mosack, the company moved its headquarters to Matthews, north carolina in 1955. in later decades, manufacturing facilities were built in Pageland and conway south carolina. The company is still privately held, with third generation Mosacks at the helm (ceo/President Glenn Mosack, execu-tive vice President cal Mosack and vice President of Marketing carole Mosack Lee).

in 1968, conbraco introduced its 70 series bronze ball valve. The famous yellow handled valve is now the most specified ball valve in the world. in 2005, the company brought all of its products under the apollo® valves brand. Prod-ucts which previously sold under the conbraco name include plumbing and heating products, water gauges, safety relief valves, marine fittings and backflow prevention devices. Those lines joined the company’s ball valves, actuators and mixing valves as part of the complete apollo valves family of products.

“as proud as we are of the conbraco tradition that goes back eight decades, it is the apollo name, and the quality and reliability that it stands for, that has won the confidence of our customers,” said cal Mosack. The company is especially

proud to emphasize its “Made in usa” tradition. Glenn Mosack stated “We actually manufacture 95% to 98% of all the components in our valves in our own plants in the carolinas, right down to the yellow handles!”

The company is vertically integrated and operates a green sand bronze foundry as well as a steel and alloy investment foundry and airset line. a wide variety of modern machining capability is joined by plating, punch press, welding, finishing and inspection equipment. apollo even manufactures its own PTFe seals! The company’s quality management system is iso 9001:2008 certified and iso 17025 certified engineering Test and calibration Labs are also on site. apollo invested over $13 million in new

equipment during the last two years alone, even during the global economic downturn.

as apollo proudly strides into the 21st century, it continues a long tradition of leadership in the valve industry. employing lean manufacturing practices in its u.s. plants has allowed the company to improve deliveries, control costs and consistently provide superior customer service. apollo’s engineering team uses the latest cad and analysis software coupled with a well equipped engineering Lab to bring products such as the 34hL hi-Lo automatic Temperature controller mixing valve from concept to production. apollo was among the first to offer a full line of products complying with low lead legislation. The newly introduced 4a/4an backflow line represents the state of the art in backflow prevention, and is among the first to comply with asse’s new “industry most stringent” backflow standards. apollo’s five year warranty on all domestically produced products is the best in the industry.

“We’re a stronger company today because of our history,” said Glenn Mosack. “Now, we’re looking toward the future.”

ASSE Deactivates All 1016-1996 Listings

on January 4, 2010, the american society of sanitary engineering removed all listings to the 1996 edition of the asse standard 1016, Performance Requirements for individual Thermostatic, Pressure Balancing, and combination Pressure Balancing and Thermo-static control valves for individual Fixture Fittings. This act was based on a decision made by the asse seal control Board on november 4, 2007 to maintain all listings to asse 1016-1996 until december 31, 2009.

in past years, a product listed to asse 1016-1996 could be used in applications requiring the mixing of hot and cold water. as prod-uct listings were granted to asse 1016-1996, a question was raised: how can an inline device be installed “where the user cannot adjust temperature and allows further mixing of hot and cold water down-stream of the device” provide the bather with thermal shock protec-tion? it was never the intent to negate the thermal shock protection that the standard had provided the user/bather. Because of this issue, additional standards were developed.

For a wider range of clearly defined applications, the 1016-1996 standard was divided into three separate documents: asse 1016-2005, Performance Requirements for automatic compensating valves for individual showers and Tub/shower combinations, asse 1069-2005, Performance Requirements for automatic Tem-perature control Mixing valves, and asse 1070-2004, Performance Requirements for Water Temperature Limiting devices. With the development of these standards and their following adoption by national model plumbing codes, manufacturers were given time to have their products tested and listed to the new standards before the deactivation of their listings to 1016-1996 on January 4, 2010. Listings to these standards can be viewed on asse’s website at: http://www.asse-plumbing.org

For more information, contact: kimberly haffey, asse Product Listing coordinator via e-mail at: [email protected].

ASSE Introduces a Lead Content Certification Program

The american society of sanitary engineering has introduced a new Lead content certification Program which is now being offered for new and current asse listings. asse’s Lead content certifica-tion Program is launched with the purpose of verifying products as having ≤0.25% percent maximum average lead content.

With recent legislative changes in states such as california and vermont, the need to verify lead content has become a necessity for manufacturers of plumbing products. The asse Lead content certification Program allows manufacturers applying for asse listings and manufacturers with current asse listings to demonstrate their compliance to new regulations as well as demonstrate their concern for the public’s health and safety.

asse’s new program includes a lead content certification test report form, which will calculate the lead content of a product being tested. These calculations are based on the test protocols set forth by the california department of Toxic substances control (dTsc). To apply for asse’s lead content certification, the lead content calculation report must be completed by an asse Listed Testing Laboratory and signed by a toxicologist authorized by the labora-tory.

New Listings

Manufacturers applying for a new listing must also ensure that an asse Listed Testing Laboratory submit a test report for the appropriate product performance standard, as listed in the seal control Board Procedures - appendices c & d, and must also complete an application packet.

Current ASSE Listed Model

Manufacturers applying for lead content certification for a current asse listed model must submit a modification request to the Prod-uct Listing coordinator, kimberly haffey, and must also instruct an asse Listed Testing Laboratory to submit the asse lead content

calculation report to the american society of sanitary engineering’s international office.

after review by asse and authorization from the seal control Board, an addendum to the seal Listing certificate will be issued stating that the models tested have ≤0.25% percent maximum average lead content.

To download a copy of the lead content certification test report form, visit asse’s website at: http://www.asse-plumbing.org

For more information and specific pricing information, contact: kimberly haffey, asse Product Listing coordinator via e-mail at: [email protected].

NOTICE - from International President Ron Murray

asse is dedicated to an open, honest consensus process for the development of product and professional standards. as such, there is the chance that current committee and working group members will be asked to resubmit applications to ensure our commitment to a fully transparent process.

also, i would like to invite any interested member to participate on the Green and sustainable committee. if you have any interest in other committees, please drop me a note. it is never too late to add a willing worker!

it has been said that there is no substitute for experience. i

would go one step further and say that there is no substitute for

experience and training. The tester, installer, repairer needs to

understand both the backflow assembly and the system it is a

part of, and they need to be familiar with the codes and

requirements of the authority having Jurisdiction. This knowl-

edge requires more than a tester certification certificate. The

asse series 5110 standard, Professional Qualifications

standard for Backflow Prevention assembly Testers, requires

a minimum of five years experience in plumbing or a related

industry field prior to attending a tester certification class. This

allows the tester the basic knowledge required to understand

the entire system, not just one small part of it. additional

training and experience should be required on fire sprinkler

system backflow prevention to ensure that testers understand

the system components, the different code requirements and

the additional tests required when shutting down this life safety

and property protection. our industry should be looking at

strengthening and expanding continuing education require-

ments and additional training for testers, repairers, and install-

ers. The work we do is too important to the public health.

in several states, there are people working to weaken the laws

governing who can test, repair and install backflow prevention

assemblies. some of these efforts are being led by the very

people and organizations who claim to promote our industry.

These efforts are being conducted by misinformed or

unscrupulous individuals or groups. Let’s work together as an

industry to ensure that qualified trained individuals, who

understand the systems they are testing, are the people we

have in the field.

INDUSTRY BUZZ

California Adopting 2009 IRC With The Residential fire Sprinkler Requirement

The state of california has adopted building code changes that will require all new one- and two-family homes and townhouses built in the state starting January 1, 2011, to be equipped with life-saving fire sprinkler systems.

The california state Building standards commission voted yester-day unanimously by a margin of 10-0 in favor of adopting the 2010 california Residential code, which includes the 2009 international Residential code as established by the international code council in september 2008. With this action, california becomes the third state to formally adopt the code. as the most populous state in the u.s., this is a huge victory for proponents of life safety. The new code requirement becomes effective January 1, 2011.

“This is another step forward in our efforts to eradicate the home fire death problem. By requiring home fire sprinklers in new homes, california adds an important safeguard for the people in the state,” said Jim shannon, nFPa President. “We are hopeful their action will lead to more states doing the same in order to save lives from fire.”

The residential sprinkler requirement was voted into the 2009 iRc code by building code officials from all over the u.s., gaining more than two-thirds of the vote. This demonstrated that officials very clearly see the need to require sprinkler technology as a life-saving measure.

it took a lot of hard work and dedication for this to become a real-ity. The caL Fire-office of the state Fire Marshal took an early lead position, by bringing stakeholders to the table to study the feasibil-ity of adopting this code. The Residential Fire sprinkler Task Force issued Phase i and Phase ii of their final report in June and July of 2009, respectively.

Standards Score a Touchdown for Super Bowl Sunday

on sunday, February 7, the indianapolis colts and the new orleans saints faced off in super Bowl XLiv. The pinnacle of the football season in the u.s., the super Bowl brings together tens of thousands of fans in person and millions more through television broadcasts. Thanks to standards, the famed game and its accompanying parties were a hit, from the first kickoff to the final field goal.

amidst the screaming fans, the high profile commercials and the abundant snacks, the highlight of the super Bowl is the football game itself. athletes are protected thanks to helmets that follow safety guidelines. asTM F717-89(2006), standard specification for Football helmets, covers new and reconditioned football helmets intended for use in competitive play and practice with particular reference to shock attenuation requirements. it was developed by asTM international, a member and audited designator of the american national standards institute (ansi).

The venue for this year’s game was the sun Life stadium in Miami Gardens, FL. Fans in the stadium had a clear view of the action because of proper lighting. iesna RP-6-01, sports and Recre-ational area Lighting, provides design criteria for new lighting systems and for the evaluation of existing installations. This docu-

ment was developed by the illuminating engineering society (ies), an ansi member and accredited standards developer.

of course, those watching at home needed to have a clear view of the game as well. Fans with cable television relied on an american national standard from the society of cable Telecommunications engineers (scTe), an ansi member and accredited standards developer, to bring the game into their homes. ansi/scTe 07 2006, digital Transmission standard For cable Television, describes the framing structure, channel coding, and channel modulation for a digital multi-service television distribution system that is specific to a cable channel.

For some, the food at a super Bowl party was half of the fun. Thanks to a number of standards developed by ansi members, popular snacks and beverages were readily available to keep viewers satisfied:

chicken wings: nsF/ansi 3-a 14159-2-2003, hygiene Require-ments for the design of hand held Tools used in Meat and Poultry Processing, developed by nsF international

Pizza: asTM F1966-03(2008), standard specification for dough divider and Rounding Machines, developed by asTM interna-tional

Potato chips: asae eP475.1 Jun96, design and Management of storages for Bulk, Fall-crop, irish Potatoes, developed by the american society of agricultural and Biological engineers (asaBe)

soda and beer: asTM F1115-95(2008)e1, standard Test Method for determining the carbon dioxide Loss of Beverage containers, developed by asTM international

Whether you’re enjoying the food or the football, standards come together each year to make the super Bowl a championship game for all.

IAPMO Releases first-Ever green Plumbing and Mechanical Code Supplement

ontario, calif. (Feb. 1, 2010) – The sustainable Building industry today has a powerful and revolutionary new tool at its disposal with the formal release of iaPMo’s Green Plumbing and Me-chanical code supplement, the most comprehensive document ever created to standardize sustainable residential and commer-cial plumbing and mechanical systems.

“The building codes are perhaps the biggest hindrance to the adoption of green buildings,” said dave viola, iaPMo director of special services and staff liaison to the Green Technical com-mittee (GTc) that developed the document. “There’s so little in-formation about how to do green systems properly and safely within existing building codes, so we’ve rolled out a document that shows exactly how it’s done.”

The Green supplement serves as a complement to any adopted plumbing and mechanical code, smoothly bridging the previ-ously troublesome gap between existing codes and established green building programs. Where code language and green build-ing concepts lack cohesion, the Green supplement creates har-mony by addressing such areas as:

• Use of alternate water sources (gray water, rainwater harvesting) • Proper use of high-efficiency plumbing products • Conservation of hot water • Energy conservation in HVAC systems • Training/education in green plumbing systems

iaPMo’s Board of directors created the GTc and charged these individuals with the development of the Green supplement in an effort to fulfill the Board’s call for a reduction in energy and water consumption as permitted in the uniform codes. established in January 2008 and comprised of a who’s who of industry leaders in all facets of the sustainable plumbing and mechanical fields, the 25-member GTc (and 60 other plumbers, contractors, engi-neers, inspectors and energy/water conservation experts enlisted for task groups) was chaired by iaPMo Board Member Bill erick-son of cJ erickson Plumbing.

“Many of the provisions in the Green supplement are very ad-vanced,” said amir Tabakh, director of environmental engineering, environmental affairs division of the city of Los angeles depart-ment of Water and Power, and a member of the GTc. “These standards are 5-7 years ahead of the local codes. as you know, a code cycle takes 3- 5 years and we cannot wait five years for products that are advanced or highly sophisticated before they are approved by the code. The Green supplement gives a local jurisdiction the opportunity to adopt a superior product, a supe-rior standard without waiting 5-7 years.”

Though provisions dealing with sustainable plumbing are promi-nent, Tabakh contends the mechanical aspects should not be overlooked. “according to the california energy commission, 30 percent of the state’s energy consumption within commercial buildings is mechanical equipment,” he said. “if that 30 percent is positively impacted, it means many more electrical systems will become highly efficient. so, this document ultimately touches national standards for electrical efficiency.”
