7202: Unit 109: Copper Pipework, Joining Copper Pipe

Multiple Choice

Why is it important for copper pipework to be shaped correctly when joining copper pipes?

• To ensure proper water flow and avoid leaks

• To make the pipes look aesthetically pleasing

• To reduce the cost of materials

• To make installation faster

Multiple Choice

Which of the following is NOT a common type of copper pipe fitting?

• Solder

• Push-fit

• Compression

• Threaded

Open Ended

Explain why cleaning is necessary after soldering copper pipe fittings.

Multiple Select

Select all statements that correctly describe the end-feed solder fitting process.

• Solder is fed in at the end when heated.

• Solder flows into the fitting by capillary action.

• Solder is applied before heating the fitting.

• Cooling creates a water-tight seal.

Open Ended

What is the function of a reducer in copper pipework?

Multiple Choice

Which end-feed component is used to seal the end of a copper pipe?

• Tee

• Coupling

• Elbow

• Stop end

Multiple Choice

Which type of copper pipe fitting is classified as non-reusable and why?

• Solder ring, because once soldered in position they cannot be moved.

• Push-fit, because they rely on an O-ring.

• Elbow, because it changes direction.

• Reducer, because it connects different diameters.

Multiple Choice

Which of the following fittings allows the pipework to change direction by 90°?

• Coupling

• Elbow

• Reducer

• Stop end

Multiple Select

Select all the features that are true about push-fit fittings for copper pipes.

• They rely on an internal rubber O-ring for sealing.

• They require soldering to be installed.

• They are pushed onto the copper pipe.

• A clean-cut end is needed to avoid damaging the O-ring.

Open Ended

Describe the function of the grab ring and O-ring in a push-fit copper pipe fitting, as shown in the diagram.

Multiple Choice

Which of the following is NOT a purpose of a reducer fitting in copper pipework?

• Connecting pipes of different diameters

• Changing direction by 90 degrees

• Reducing pipe diameter

• Joining two pipes

Multiple Choice

Which push-fit fitting is used to change the direction of pipework by 90 degrees?

• Elbow

• Tee

• Coupling

• Reducer

Multiple Choice

Which material is commonly used for the 'olive' in compression fittings for joining copper pipes?

• Copper or brass

• Plastic

• Steel

• Aluminum

Multiple Choice

Which of the following compression fittings allows the pipework to change direction by 90°?

• Elbow

• Coupling

• Tee

• Reducer

Multiple Choice

What is the purpose of the small fiber washer in a tap connector, and where is it placed?

• To create a water-tight seal between the tap connector and the base of the tap or float-operated valve

• To prevent corrosion between the pipe and connector

• To hold the connector in place

• To reduce noise in the pipe

Open Ended

After learning about joining copper pipe, what is one question you still have or something you would like to know more about regarding copper pipework?

Multiple Choice

What are some reasons why fittings are required when working with copper pipework?

• To join lengths of copper together, change the direction of pipework, add a connection, or connect to an outlet

• To increase the thickness of the pipe

• To make the pipe rust-resistant

• To reduce the cost of materials
