Session 7: Basic plumbing tools and materials (1-1½ hours)

Time: 1-1½ hours

OBJECTIVES: By the end of this session trainees will have o learned and demonstrated basic plumbing skills necessary for constructing and installing a hydram.

OVERVIEW: The session should familiarize participants with all commonly used plumbing tools and pipe fittings, although project-specific skill requirements may vary with the type of hydram construction foreseen and the availability of tools at the work sites. Participants learn:

- to identify tools and fittings (including host country language names, where possible);

- to use the tools properly and competently; and

- to explain and demonstrate safety precautions necessary in use of plumbing tools, especially torches and power tools when used.

MATERIALS:

-Pipe joint compound or TFE tape

- Cutting oil and rag

- Miscellaneous pipe fittings and pipe, galvanized and PVC

- PVC cleaner and glue

- Handout 7A

TOOLS: Pipe vise, two pipe wrenches, chain wrench, pipe threader, spud or monkey wrench, etc. (the quantities may increase depending upon the number of trainees but basically all the tools needed for all the exercises should be present and discussed), pipe-cutter or hacksaw.

 

PROCEDURES

NOTES

1.

State the objective of this session and explain that the skills the trainees are expected to develop are necessary for hydram installations.

Be certain to mention that on a 1x1x½" tee, the ½" = dimension refers to the arm of the tee.

2.

Show the fittings one at a time to all the trainees explaining their purpose and nomenclature.

 

3.

Demonstrate the use of- pipe joint compound or TFE tape.

It is important to stress that their purpose is three-fold; to seal, to facilitate easier

4.

Demonstrate the use of all the tools and any necessary safety precautions.

installation, and to facilitate easier removal.

5.

Set up 2 or 3 workstations, one with pipefittings laid out and labeled, another with a threader and cutting and/or joining station. Have one trainer at each station and the participants revolving to each station. Allow the trainees to practice using all the tools until they and the instructor are confident with their ability to properly use them.

If at all possible, actual fittings and tools should be demonstrated and practiced on. Attachment 7A can be used to describe the fittings if lack of time or facilities prevent "hands-on" practice. The handout is more useful as a learning reinforcement and as an aid for the trainees to use in describing and acquiring fittings at a plumbing supply house.

   

Names of materials and tools may be different from what is used in the U.S. It is important to find out what each are called and call them by the local name.
