Introduction

We are pleased to present this summary of residential

plumbing standards. The goal of this project is to

establish national standards for the residential

construction industry that reflect industry skill

requirements. The standards will provide a basis for

the certification and training of workers as well as

objective benchmarks for employee selection and

training needs. In addition, educators will find the

standards useful for designing curricula and evaluating

individual training outcomes.

These standards by themselves do not represent a

model training program. Rather, these standards are

designed to be a source in developing training

programs and curricula and evaluating outcomes of

residential plumbing training programs.

Residential plumbing standards have been developed

and validated for trainees entering their second year of

training and journey level plumbers. Standards are

developed and validated for the following nine

plumbing specialties: Public Water and Sewer

Connections, Private Water and Sewer Connections,

Lift Stations and Sewage Systems, Water Quality and

Filtration Systems, Solar Systems, Hydronic Heating

Systems and Boilers, Gas Piping, Backflow Protection,

and Irrigation Protection. Thirteen (13) critical work

functions or duty areas are identified.

Critical work functions describe the major tasks and

content areas of work within a specialty. Key activities

or major tasks and knowledge involved in completing

critical work functions are also provided.

Performance Indicators, or skill standards, which help

determine when and key activities are being

performed competently are referenced to critical work

functions.

In addition, applied academic skills required to perform

key activities are provided. These include

mathematics, communications, science and applied

academic skills. Safety requirements involved in

completing key activities have also been identified.

Residential Plumbing Skills Standards Page 3 of 61

This report summarizes each of the thirteen critical

work functions or duty areas into two pages. The first

or front page lists the critical work function and

plumbing specialties that perform the work function.

Key activities, performance indicators, applied

academic skills and safety requirements are also listed

on the front page. Page references from Delmar’s

Plumbing Technology text 4th edition 2001 are

provided for many key activities.

Descriptions of the codes used on the first page of

each standard are listed on the second or back page.

This format offers a concise presentation of the critical

parts of each standard. For more detailed information

the reader is encouraged to review the complete

report Residential Plumbing Standards Volume I

published by the Home Builders Institute.
