HOW TO USE THIS COMPETENCY BASED LEARNING MATERIAL

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

The unit of competency “Preparing Pipes for Installation” contains

knowledge, 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 to complete each learning outcome of the module. In each learning outcome are Information Sheets and Instruction Sheets (Reference Materials for further

reading to help you better understand the required activities.) Follow these activities on your own and answer the self-check at the end of each learning outcome. 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 covered

in 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 a

particular 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 or Certificate of Competency from previous training, show it to your trainer. If the skills you acquired are still current and relevant to the unit/s of competency

they may become part of the evidence you can present for RPL. If you are not sure 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 of Achievement is also provided for your trainer to complete once you complete

the module.

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 to make any interpretation of a plan if he/ she do not know the plumbing symbols and abbreviation indicated in the plumbing layout or print and specifications

SYMBOLS AND ABBREVIATIONS A common set of symbols are used on architectural prints to represent

materials, building objects, and various dimensions and locations. Piping symbols are used by architect and mechanical engineers on prints to represent plumbing 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. Specifications are written information that supplements the prints and

provides 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 as

brands and types of plumbing fixtures and equipment. See figure 1.1

Note: Symbols and Abbreviations in plumbing trade may appear similar in

other qualification but it may have different meaning and application.

INTRODUCTION: Plumbing as defined as the installation of pipes, fitting, fixtures and

other apparatus in conveying and supplying water into different parts of the building and to dispose and discharge waste water and other substances out of

the building. This module tackles about the different plumbing materials those plumbing codes permit to use.

PLUMBING MATERIALS KINDS/ TYPES AND CLASSIFICATION The Revised Plumbing Code of the Philippines specifies the type of piping

materials that may be used for each plumbing system. Plumbing code bases of selecting materials are the soil types, ground condition, local rainfall and frost

or freezing conditions. Consult the plumbing code to ensure that only code-approve material is being used for plumbing system.

Pipe is a cylindrical tube used for conveying potable water, wastewater,

waterborne waste, and air from one location to another. There are numerous kinds of pipes available for plumbing installation but

so far, the most popular and commonly used are:

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



explain, identify and perform safety handling of hand tools.

INTRODUCTION:

In this information sheet contains OH& S on handling both hand and power tools. One’s a plumber practice safe handling of tools he/ she can avoid accident, injury which may result into death or damage to property. On the

other hand if the plumber did not practice such safety handling of tools it may have 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.

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
