ABSTRACTThe occupational analysis contains a brief job

description, presenting for the occupation of plumbing 12 detailedtask statements which specify job duties (tools, equipment,materials, objects acted upon, performance knowledge, safetyconsiderations/hazards, decisions, cues, and errors) and learningskills (science, mathematics/number systems, and communications). The12 task statements cover the following performance duties: installingbuilding sewer, installing building drains and storm sewers,installing and/or maintaining drain waste and vent systems, watersupply systems, installing and/or maintaining domestic hot and coldwater distribution systems, installing and/or maintaining gas and/oroil systems, installing and/or maintaining hydronic heating systems,installing and/or maintaining fire protection systems, installingdnd/or maintaining private sewer disposal systems, setting and/orrepairing fixtures and fixture trim, and repairing plumbing fixturesand/or fixture trim.

FOREWORD

The occupational analysis project was conducted by

The Instructional Materials

Laboratory, Trade and Industrial Education, The Ohio

State University in con-

junction with the State Department of Education,Division of Vocational Educa-

tion pursuant to a grant from the U.S. Office of

Education.

The Occupational Analysis project was proposed and

conducted to train voca-

tional educators in the. techniques of making acomprehensive occupational

analysis.

Instructors were selected f.04,ft Agriculture, Business,

Distributive,

Home Economics and Trade and Industrial

r..lucation to gain experience in

developing analysis documents for sixty-one different

occupations.

Represen-

tatives from Business, Industry, Medicine, and Education were

involved with

the vocational instructors in conducting theanalysis process.

The project was conducted in three phases.

Phase one involved the planning

and development of the project strategies.

The analysis process was based

on sound principles of learning and

behavior.

Phase two was the identifica-

tion, selection and orientation of allparticipants.

The training and work-

shop sessions constituted the third phase.

Two-week workshops were held

during which teams of vocational instructorsconducted an analysis of the

occupations in which they

had employment experience.

The instructors were

assisted by both occupational consultants and subject

matter specialists.

The project resulted in producing one

hundred two trained vocational instruc-

tors capable of conducting andassisting in a comprehensive analysis of

various occupations.

Occupational analysis data were generated for

sixty-one

occupations.

The analysis included a statement of the

various tasks performed

in each occupation.

For each task the following items were

identified:

tools and equipment; procedural knowledge;

safety knowledge; concepts and

skills of mathematics, science and communicationneeded for successful per-

formance in the occupation.

The analysis data provided a basis for generating

instructional materials, course outlines,student performance objectives,

criterion measures

as well as identifying specificsupporting skills and

knowledge in the academic subject areas.

PREFACE

This document represents a wide overview of the job

of plumbing with related piping.

Due to time limitation and the scope of the plumbing industry,

much of the information is

generalized.

It was not the intent of the authors to be more specific.

A reading of the

area on Hydronic Heating should not be

construed as being complete, but rather as an attempt

by the authors to indicate some areas

of hydronics that the plumber-mechanic often encounters.

The occupation of plumbing is becoming more sophisticated

with each passing day.

One

only needs to understand the relationship between quality

plumbing and its effect on

environment, and the sophistication becomes

self-evident.

With the impact of environmental

concerns, experienced in news andmanifested in recently enacted legislation, the complexities

of plumbing will become even greater.

In order to stay within the time slotted and still produce a

valid analysis, the authors

chose to examine plumbing on the basis of the primary systems

that are encompassed by the

occupation.

Also, for validity, the author established empirical priority

in the selection

of systems to be analyzed.

ACKNOWLEDGMENT

We wish to acknowledge the valuable assistance rendered by the following

subject matter specialists.

They provided input to the vocational instruc-

tors in identifying related skills and concepts of each respective subject

matter area and served as training assistants in the analysis process during

PERFORMANCE KNOWLEDGE (CON'T)

Isometric paper

Pencil (with eraser)

Scale

Manufacturer's equipment data

Local code book

Pipe flow-rate tables

Blueprints and/or building drawing

Local water department regulations

Draw a schematic of water system, show

all fixtures supplies and risers by

means of appropriate letters and num-

bers.

Indicate each floor elevation

and the highest (furthest) water out-

let to be supplied

For pressure or gravity supply tanksys

tems, show minimum water level at

which tank is designed to operate at

peak demand

Indicate the minimum pressure required

f.dr satisfactory operation at the

highest (furthest) water outlet and

minimum pressure available at all

times at the source

Mark on the drawing the total load in

terms of water supply fixture units

(Note:

fixtures having both hot and

cold water outlets should be taken as

3/4of list unit value for said fixture

Mark on the drawing adjacent to all

fixture notations, the demand for

each in g.p.m. (Note:

indicate thos1

fixtures of continuous use, e.,g. ir-

rigating equipment, AC equipment,

and add them to the other fixtures)

Assume condition of noflow - refer to

third step - the difference from the

third step will establish hints for

friction losses

Determine the basic circuit (Note:

this will be longest developed length

of pipe)

Mark on drawings pressure loss due to

equipment, e.g. meters, softners, etc

Subtract eighth step from sixth, this

will give the pressure available for

basic circuit

Calculate pipe lengths and add 50% for

fittings and valves

Use sizing tables, check flow rates of
