Life4

Life4 the performance standard

The benchmark for weathering tests for rainwater systems is setout within European standards*. The weathering test essentiallymimics actual conditions, but also accelerates them in order thatlong term performance may be assessed. This articial ageing typetest consists of 1600 hours of exposure to high intensity UV lightingwith specied levels of irradiation and condensation, which is

designed to emulate approximately 3 years of natural weathering.Standard Marley rainwater systems achieve excellent results whenmeasured to this requirement.

In order to demonstrate the enhanced performance of Life4,gutters and downpipes were exposed to the articial ageing testfor up to four times this duration (6400 hours). Measurementstaken after this extended test showed that the extent of colourfade was still well below that permitted in the European Standardafter 1600 hours.

Life4 the science of production

Life4 uses a higher specication material to form a capping layeron the outside of the gutter or pipe. This material is by its verynature more durable and has a high gloss nish.

The remaining material used in the product is standard PVCucontaining 15% post production recycled material. All materialsare lead free.

Rainwater systems that staylooking better for longer

We're all affected by the steady advance of time. Years ofexposure affects how everything looks. Marley Plumbing

& Drainage have advanced the manufacturing processto create Life4. Life4 rainwater systems can withstandexposure for up to four times longer than standard PVCurainwater gutters and downpipes.Looks better...

Life4 gutters and downpipes have high gloss levels that are consistent with the ttings,improving the overall aesthetic of the system. The gloss level is typically 85% comparedto a norm of 40 - 50% on standard systems.

...for longer

Not only do Life4 products look better, they last longer. Life4 products have been exposed toup to four times the European weathering test duration and performed admirably (see right).

Key components

Easyclip

Deepow, Clip-master, Flowline andDeepow150 rainwater systems benetfrom the Marley easyclip, which makesjointing both easy and reliable. Theeasyclip has twin compression tabs, whichapply downward pressure onto the gutterseal, to ensure a watertight joint. A positiveclick is made when the gutter is in place.The easyclip also makes life easy if youneed to dismantle the joint.

Notch adaptor (RGNA1)

It is possible to adapt the easyclip to makettings suitable for notch jointing, bytting a notch adaptor into the centre ofthe easyclip. The adaptor will then t into anotch cut into the back of the gutter.

This is an effective way of allowing gutter toexpand and contract due to temperaturechange without gutter and tting pullingapart. There is also no need to anchorttings to the fascia, an ideal solution whenusing rafter arm brackets (see page 13).

Marley rainwater systemsoffer complete roofdrainage solutions for avariety of building sizesand styles. Picturedis a selection of keycomponents within therange. For rainwater

product specications,see pages 20 35.

Pipe clips

Two different pipe clip xing methodsare available. A one piece clip for ushxing or a two piece clip to t both thedownpipe and pipe socket. These areused with backplate RCB300 and allowfor adjustment.

Socket clip

The socket clip ts neatly around theiconic Marley socket, keeping the cliprmly in place.

The iconic Marley socket

The origins of the iconic double bumpon our rainwater pipe socket stemfrom the fact that Marley was the rstcompany in the UK to manufacturerainwater gutter. The design emulatedthe traditional material most oftenused for drain pipes, cast iron.

Roof drainage design

1. Effective roof areaThe effective roof area can be determined bycalculation in accordance with the following:

BS EN 12056-3:2000, Roof drainagelayout and calculations.

The Building Regulations 2002Approved Document H, Part H3.

The formula and example shown belowreects the method used in the abovestandard to calculate effective roof area.

Multiplication factors

An alternative approach to that describedabove is the use of multiplication factors toestablish effective roof area. From plan areathe appropriate factor for the roof slope canbe applied to determine the effective area.

Effective roof area Multiplication factor method Outlet at one end Outlet at one endwith an angle

within 2m of outlet

Outlet in centre

This method is similar to that shownin Approved Document H of the BuildingRegulations. The table below providesa wider range of factors to enableaccurate assessment of effective roofarea to be determined.

Vertical surfaces

Where pitched roofs abut vertical walls thecatchment area is likely to be increased asa result of wind driven rain. To allow forthis half the vertical surface area of thewall should be added to the effective areaof the sloping roof.

Flat roofs

For roofs with a pitch of less than 10 , theeffective area is taken as the plan area.

2. Rainfall intensity

The Building Regulations 2002 ApprovedDocument H and BS EN 12056-3: 2000provide detailed information on rainfallthroughout the UK by geographicallocation and frequency of occurrence.The ow rates shown below for MarleyPVCu gutter systems have been determinedfrom tests carried out in accordance withthe test procedure in BS EN 12056-3: 2000.

Gutter selection

Although aesthetic appearance is animportant aspect in the selection of aparticular gutter system, the followingfactors also need to be taken intoconsideration as they could inuence thenal choice of system.

The size of gutter and its ow capacity.

Whether the gutter is tted level orto a fall.

If end or centre outlet position fordownpipes are adopted.

The length of gutter to an outlet/downpipe.

3. Flow capacity

The maximum ow capacity of differentMarley gutter systems can be comparedfrom the tables shown below. The capacityof each system varies depending onprole, size and whether the gutter istted level or to a fall. For design purposeseaves gutters are normally sized to ensurethe calculated run-off does not exceed90% of the gutter capacity. It is alsorecommended that gutters are xed levelas this enables the gutter to be tted ashigh as possible to ensure the correct

relationship is maintained at the roof edge.

Effect of valleys

Where valleys occur it is good practice toposition an outlet adjacent to the internalangle to deal with the concentrateddischarge that is likely at such points duringpeak ow conditions. Depending on the sizeof roof it may also be benecial to t a cornerhopper where the ow is considerable.

4. Rainwater pipe sizes

With the exception of the Deepow150gutter system which has an 82mm diameterdownpipe, all other Marley PVCu guttersystems incorporate outlets suitable for68mm circular or 65mm square rainwaterpipes. This size of downpipe has beenselected as it has the necessary capacity toaccommodate the maximum ow from anyof the gutter systems.

Design basis

To assess the suitability of a gutter system to drain the roof of a building the followingfactors need to be taken into consideration:1. The effective roof area to be drained.

2. Rainfall intensity.

3. The ow characteristics of the gutter system.

4. The number and position of downpipes.

Installation data

Rafter arm brackets

Rafter arm brackets can be used with all Marley gutter systems. Additional structuralxings should be provided when used with a clip-jointed gutter system, to enable keyttings to be anchored and supported for the control of thermal movement.

It is recommended that notched gutters are used on buildings without fascia boards askey ttings such as unions and outlets do not need to be secured and can be positionedadjacent to structural xing points. Top rafter brackets, RTA1 or RTA1A, will need tobe tted before the roof is tiled. Side rafter brackets, RSA1 or RSTA1A, may be ttedafterwards and are easily adjusted to accommodate minor variations in line and level.Nuts and bolts are supplied to secure fascia brackets to the rafter arm. Although xingsare controlled by rafter centres it is important to meet gutter support recommendationspreviously described.

Gutter position

The spread of water as it leaves the roof edge can vary considerably depending on the rainfall intensity, type of roof surface and thepitch of the roof. BS EN 12056-3: 2000 recommends that eaves gutters should be tted in such a position that they intercept the owat the roof edge and that gutters are tted centrally under the roof tile and close beneath it.

Gutters can be installed level or with a nominated gradient of 1:600. If tted to fall, care should be taken to ensure the top of the gutter does notfall below the roof tile to such an extent that the water will pass over the front edge of the gutter. It is also important that the eaves course of thetile or slate should not project too far over the fascia board and a maximum of 50mm is recommended for 112-125mm nominal size gutters.

Fascia brackets

All Marley PVCu gutter fascia brackets havebeen tested to the loading tests as detailedin BS EN 1462 and perform in excess of the

highest classication, Class H heavy duty,which requires brackets to support a deadweight load of 75kg, to simulate snow load.

It is recommended that brackets are xedwith the aid of a string line to maintainalignment and bracket centres must notexceed 1m maximum centres. When xingto cellular fascia boards the two outermost xing holes must be used and 1" x10g (32x5mm) pan or round head non-ferrous screws must be used. The use ofcountersunk screws is not recommended.

When xing to cellular fascia boards of lessthan 16mm thick, a timber support battenshould be tted behind to ensure a securexing is obtained. To improve the loadingcharacteristics of the gutter system, fasciabracket centres can be reduced but in

areas of the country that experiencefrequent heavy snow fall, the use of snowboards is recommended as advised in

BS EN 12056-3: 2000.The use of the gutter bracket centrexing hole is not recommended and isprovided to facilitate the adjustablerafter arm brackets RSA1A and RTA1A.

Roof and balcony outlets

Marley provide a range of roof outlets,sized to suit various applications.68mm PVCu outlets are shown onpage 35. Aluminium outlets, sized50-150mm are shown in the Alutec Roofand Shower Drainage Guide.

Rise and fall brackets

Rise and fall brackets, RKF1, can be used with clip-jointed gutters although a notchedsystem is recommended as described for rafter arm xing above. Nuts and bolts aresupplied to secure fascia brackets to the multi-t face plate. It is recommended thatpilot holes are drilled in mortar joints before the spike is driven in to avoid cracking thebrickwork bond. Bracket centres should not exceed 600mm.

Angle fascia bracket

Angle fascia bracket adaptors, RKA1, RKA2, are required when a sloping fascia boardis employed at the eaves. The galvanised mild steel adaptor is tted behind the fasciabracket with two 1 x 10g (45x5mm) non-ferrous round head screws passing throughboth bracket and adaptor.

Use two parallel thread screws which are longenough to penetrate the rear face of the board.

If the cellular board is less than 16mmthick, fit timber support batten as shown.

Gutter jointing

Clip-jointed gutter systems

Each joint is made by inserting the plain edge of gutter into thetting and locating under the rear clip. At the same time ease thefront edge of tting forward and up until the gutter clips underthe front edge. Care must be taken to ensure that each lengthof gutter is tted to the insertion mark on each tting. This isparticularly important and attention to this will ensure troublefree performance for many years.

Unions and outlets incorporate xing holes in the rear edge whichmust be used to secure the tting to the fascia board. This isessential for the control of thermal movement that occurs with

temperature variations. The length of gutter to a stopend from atting must not exceed 300mm. Where this is exceeded a unionmust be tted and secured as previously described with a shortpiece of gutter to the stopend. With Deepow, Deepow150,Clip-master and Flowline the length of gutter to a stopend canbe retained using the notch technique and adaptor RGNA1 toeliminate this particular restriction (see opposite).

Notched gutter systems

It is possible to adapt the easyclip to make ttings suitable fornotch jointing, by tting a notch adaptor into the centre of theeasyclip. The adaptor will then t into a notch cut into the backof the gutter.

This is an effective way of allowing gutter to expand and contractdue to temperature change without gutter and tting pullingapart. There is also no need to anchor ttings to the fascia. Thismethod is ideal to anchor the last joint of a gutter run which endswith a stopend.

To watch a video demonstration of notch jointing, go to

www.marleyplumbinganddrainage.com/videos/4rainwater.html

The Classic system is jointed by means ofpre-tted clips on all ttings.

The notched gutter end is located under the notch adaptor and thejoint completed by clipping the gutter under the easyclip on thefront of the tting.

When correctly assembled, a notched joint cannot pull apart andwill absorb expansion and contraction associated with variations intemperature, while maintaining a watertight seal.

Using a notching tool, RGN1, notch the rear of the gutter.Notches must be made to both ends of a length of gutter.

A notch adaptor RGNA1 is then inserted into the easyclip from theunderside, between the gap in the body of the tting and the cliparm. Insert one end of the short side of the adaptor into the openend of the easyclip. Twist the other side of the adaptor into place.The adaptor is necessarily a tight t to ensure it stays in place.

Deepow , Deepow150 , Clip-master and Flowline can be installed as notched systems.

Downpipes

General

As rainwater pipes are generally tted externally, joints betweeneach spigot and socket length do not need to be sealed. Howeveroffset ttings are sized to allow for push t or solvent weld jointing.

Gutter outlets are normally positioned directly above drainconnections but on occasions it may be necessary to rotate theoffset to avoid obstructions below. However when using thesquare downpipe system, the gutter outlet should be positioneddirectly above the rainwater drain connection, as square offsetscannot be rotated.

Where a RH25 hopper head is used, the RLE3 outlet adaptor with

a pipe socket are required to provide the necessary transition fromcircular to square.

Circular downpipe systems

Marley Deepow , Classic , Flowline and Clip-master gutters

all have outlets designed to suit 68mm circular downpipe,which has sufcient capacity to accommodate the maximumow from the above gutter systems.

Square downpipe systems

Marley Flowline and Classic gutter systems are available

with outlets suitable for 65mm square and 68mm circularrainwater pipes. For aesthetic reasons, the 65mm squaresystem is normally preferred but both have sufcient capacityto accommodate the maximum ow from either system.

1. Offset assembly

Offsets can be easily constructed on site from a range of bendsdepending on the roof overhang at the eaves.

Where offsets exceed 600mm it is recommended that bendsare solvent welded to gutter outlet spigots to ensure a positiveconnection. When two 87 bends are used to construct anoffset the horizontal section of pipe should be supported witha pipe clip from the soft.

2. Location of pipe clips

Every rainwater pipe should have a clip located round the topsocket to support the downpipe system. Intermediate clips shouldthen be located at a maximum of 1.8m centres or in the middleof each length to maintain alignment. A gap of 10mm should beleft between the end of each pipe and the bottom of the socketto allow for thermal movement.

Two different pipe clip xing methods are available. A one piececlip for ush xing or a two piece clip to t both the downpipeand pipe socket. These are used with backplate RCB300 and

allow for adjustment.Each should be secured with two 32 x 6.5mm non-ferrous roundhead screws. An extension backplate RT200 can also be used forgreater adjustment of the downpipe from the wall.

3. Drain connections

External rainwater pipes usually connect direct to the surfacewater drain. Where a direct connection is made a reducerand a short section of pipe is used to provide the transitionbetween different pipe sizes. A gully trap will be required to botharrangements where the drain connects to a combined foul andsurface water drainage system.
