HOW TO USE THIS COMPETENCY BASED LEARNING MATERIAL

Welcome to the module in Prepare Pipes for Installation. This modulecontains training materials and activities for you to complete.

The unit of competency “Preparing Pipes for Installation” containsknowledge, skills and attitudes required for Plumbing. It is one of the core

competencies at National Certificate level II (NCII).

You are required to go through a series of learning activities in order tocomplete each learning outcome of the module. In each learning outcome areInformation Sheets and Instruction Sheets (Reference Materials for further

reading to help you better understand the required activities.) Follow theseactivities on your own and answer the self-check at the end of each learningoutcome. You may remove a blank answer sheet at the end of each module (or

get one from your facilitator/trainer) to write your answers for each self-check.

If you have questions, don’t hesitate to ask your facilitator for assistance.

Recognition of Prior Learning (RPL)

You may already have some or most of the knowledge and skills coveredin this learner’s guide because you have:

been working for some time

Already completed training in this area.

If you can demonstrate to your trainer that you are competent in aparticular skill or skills, talk to him/her about having them formally recognized

so you don’t have to do the same training again. If you have a qualification orCertificate of Competency from previous training, show it to your trainer. If theskills you acquired are still current and relevant to the unit/s of competencythey may become part of the evidence you can present for RPL. If you are notsure about the currency of your skills, discuss this with your trainer.

At the end of this module is a Learner’s Diary . Use this diary to record

important dates, jobs undertaken and other workplace events that will assist you in providing further details to your trainer or assessor. A Record ofAchievement is also provided for your trainer to complete once you completethe module.

Learning Objectives:

After reading this INFORMATION SHEET, YOU MUST be able to explain, identify standard plumbing symbols, abbreviation.

INTRODUCTION

In addition to practical training with tools and materials, a plumber must

learn to the plumbing symbols and abbreviation. It is difficult for a plumber tomake any interpretation of a plan if he/ she do not know the plumbing symbolsand abbreviation indicated in the plumbing layout or print and specifications

SYMBOLS AND ABBREVIATIONS

A common set of symbols are used on architectural prints to representmaterials, building objects, and various dimensions and locations. Pipingsymbols are used by architect and mechanical engineers on prints to representplumbing fixtures and piping systems , as well as pipe fittings and valves used

to construct plumbing systems.A print is a drawing showing a building structure and all of its

components. Prints are also referred to as blueprints or working drawings.Specification s are written information that supplements the prints andprovides additional details that could not be shown on the prints or that

require additional description such as information on legal responsibilities,insurance, quality of workmanship, and other necessary details such asbrands and types of plumbing fixtures and equipment. See figure 1.1

Note: Symbols and Abbreviations in plumbing trade may appear similar inother qualification but it may have different meaning and application.

LEARNING OBJECTIVES:

After reading this INFORMATION SHEET, YOU MUST be able toidentify and select plumbing fittings needed in a specific job.

INTRODUCTION:

This information sheet contains standard plumbing fittings, their uses

and descriptions. These fittings are essential materials in plumbing

installation, without fittings it is merely impossible to connect pipes forinstallation.

COMMON PIPE FITTINGS

Plumbing installation process utilizes fittings to connect pipes. Plumbingfittings comes in different materials such as PVC, galvanize iron, cast iron,UPVC, copper and etc. Fittings have different function or purpose and uses forplumbing installation either for water supply or waste drainage system.

Plumbing fittings have different shapes which allow rigid straight pipe tochange both direction and diameter.

Figure 2.1 Show the plumbing fitting name, description, uses and image.

Information Sheet No. 1.1-3Plumbing Tools and Equipment’s for installation.


After reading this INFORMATION SHEET, YOU MUST be able to identify anddescribe plumbing tools and equipment for plumbing installation.

INTRODUCTION

Include in this information sheet are the different plumbing tools and

equipment’s in plumbing installation. Tools are categorized in to two, the hand

and power tools. Tools are also fall into different classification such asCutting, Measuring, Holding, Driving Tools and etc. It is a must for theplumber to select properly what tools and equipment needed according to jobspecification.

Plumbing Tools

Plumbing tools fall under one of two categories: 1. Hand tools

Manually operated.

Not as expensive as power tools.

Equally important in completing a task or project.

Most employers expect a plumber to have basic hand toolswhen being considered for employment.

See Figure 3.1 for the plumbing tools and their correspondinguses.

Information Sheet No. 1.1-4Hand and Power Tools safety


After reading this INFORMATION SHEET, YOU MUST be able to explain, identify and perform safety handling of hand tools.

INTRODUCTION:

In this information sheet contains OH& S on handling both hand andpower tools. One’s a plumber practice safe handling of tools he/ she can avoidaccident, injury which may result into death or damage to property. On theother hand if the plumber did not practice such safety handling of tools it mayhave a reverse result.

HAND AND POWER TOOL SAFETY

Plumbing tools are classified into two; the HAND TOOLS and the POWER

TOOLS.

Differences between hand and power tools:

– Hand tools have no power source, other than the physical force

applied by the user. Hand tools include anything from axes to

hammers, and screwdrivers to wrenches

– Power Tools require a non-human power source to function

properly--e.g. External (electricity, compressed air, etc.) or

Internal (battery pack, internal combustion engine, etc.).

Both kinds of tools require specific safety precautions or rules to be

followed; yet some rules will apply to both.

There are five basic rules that apply to all tools used either hand or

power and general safety rules that govern with the use of hand tools

5 Basic Rules

Keep all tools in good working order

Use the tool only for what it is designed to do

Examine the tool for damage before each use

Always follow the manufacturer’s instructions when operating any

tool

Always wear the appropriate PPE when operating any tool

GENERAL “Hand Tool” SAFETY

RULES

Carry all sharp tools in a holster or sheath

Tag worn, damaged or defective tools and do not use them

Do not perform “makeshift” repairs to tools

Do not use cheater bars

The Greatest Hazards of Hand Tools: Misuse/Improper Maintenance

Using a screwdriver as a chisel Could cause the tip to break and fly, hitting either the operator or

bystanders A wooden handle on tool such as a hammer or an axe is loose, splintered

or cracked

The tool head could fly off and strike the operator or bystanders Impact tools, e.g. chisels and wedges, are unsafe if their heads are

“mushroomed”

The heads might shatter on impact sending sharp fragments flying Wrenches must not be used if the jaws are sprung, cracked or twisted

The wrench could slip off
