Priya is learning how to use a bending machine. What is the first step she should take?

• Bend the tube to 90 degrees.

• Measure the distance required and mark it on the tube.

• Place the 4d mark on the bending machine.

• Measure back four diameters of the tube size.

Answer explanation

The first step in using a bending machine is to measure the distance required and mark it on the tube. This ensures accurate bending according to specifications before proceeding with the actual bending process.

Oscar is working on a plumbing project and needs to join copper pipes. Which method involves pushing to join copper pipes?

• Push-fit fittings

• Twist fittings

• Snap fittings

• Lock fittings

Answer explanation

Push-fit fittings are designed for easy installation by simply pushing the pipes together, making them the correct choice for joining copper pipes without the need for soldering or additional tools.

Leo is learning plumbing and wants to know which fitting type requires extra solder to be added?

• End feed

• Integral solder ring

• Compression fitting

• Push-fit fitting

Answer explanation

End feed fittings require additional solder to create a secure joint, as they do not have a pre-applied solder ring. In contrast, integral solder rings already contain solder, and other types like compression and push-fit fittings do not require solder.

Arthur is learning plumbing and needs to know the second step in solder ring fittings. What should he do next?

• Pipe is cleaned on outside.

• Flux is added.

• Joint is heated.

• Joint is wiped clean.

Answer explanation

The second step in solder ring fittings is to clean the outside of the pipe. This ensures proper adhesion and a strong joint when soldering, making it a crucial preparatory step before applying flux or heating the joint.

Sophie is learning plumbing and wants to know: What is the first step in end feed fitting?

• Flux is added.

• The pipe is cut then the joint is cleaned inside.

• Solder is added.

• Joint is wiped clean with cloth.

Answer explanation

The first step in end feed fitting is to cut the pipe and clean the joint inside. This ensures a proper fit and prepares the surfaces for soldering, making it essential before any other steps like adding flux or solder.

Benjamin is learning plumbing and wants to know: What is the purpose of adding flux in the end feed fitting process?

• To cool the joint

• To clean the pipe

• To help solder flow

• To heat the fitting

Answer explanation

The purpose of adding flux in the end feed fitting process is to help solder flow. Flux cleans the surfaces and prevents oxidation, allowing the solder to adhere better and flow smoothly into the joint.

Priya is learning how to install plumbing pipes. What is the second step in the end feed fitting process?

• Add flux

• Clean the pipe on the outside

• Heat the fitting

• Wipe the joint with cloth

Answer explanation

The second step in the end feed fitting process is to clean the pipe on the outside. This ensures proper adhesion and prevents contamination before applying flux and heating the fitting.

George and Sophia are discussing plumbing. What are the two styles of compression fittings mentioned?

• Type A and Type B

• Type X and Type Y

• Type 1 and Type 2

• Type C and Type D

Answer explanation

The correct answer is Type A and Type B, as these are the two styles of compression fittings specifically mentioned in the question. The other options do not correspond to the styles referenced.

Oscar is working on a plumbing project. What materials should he use for Type A compression fittings?

• Half-hard copper and plastic pressure pipe

• Steel and iron

• Wood and glass

• Rubber and fabric

Answer explanation

Type A compression fittings are designed for use with half-hard copper and plastic pressure pipe, as these materials provide the necessary strength and flexibility for secure connections. Other materials listed are not suitable.

Freya is learning plumbing and needs to use a Type A fitting. What is the first step she should take?

• Cut the pipe square

• Paint the pipe

• Bend the pipe

• Heat the pipe

Answer explanation

The first step in using a Type A fitting is to cut the pipe square. This ensures a proper fit and alignment when connecting the pipe to the fitting, which is crucial for a secure and leak-free joint.
