Question 1

How do you connect MDPE pipes?

Accepted Answer

Connecting MDPE pipes involves using compression fittings, which consist of a nut, an O-ring, and a compression ring. First, cut the pipe to the desired length and ensure that the ends are clean and free of debris. Then, slide the nut and O-ring onto the pipe, followed by the compression ring. Insert the pipe into the fitting and tighten the nut until it is snug. Repeat the process for the other end of the pipe, and ensure that the joint is leak-free before using the pipe.

Question 2

How do you connect blue plastic pipes?

Accepted Answer

To connect blue plastic pipes, you will need to use PVC cement and primer. First, clean the ends of the pipes with a PVC cleaner. Then, apply the primer to the ends of the pipes and let it dry. Finally, apply the PVC cement to the ends of the pipes and push them together firmly. Hold the pipes together for a few seconds to allow the cement to set.

Question 3

Can MDPE gas pipe be used above ground?

Accepted Answer

Yes, MDPE gas pipes can be used above ground. However, it is important to ensure that the pipe is properly protected from UV rays and other environmental factors that can cause damage or deterioration. It is recommended to use a protective sleeve or paint to protect the pipe.

Question 4

Can you use plastic pipe without inserts?

Accepted Answer

It depends on the type of plastic pipe you are using and the application. Some plastic pipes, such as PEX, do not require inserts for certain fittings, while others, such as PVC, typically require inserts to ensure a secure connection. It is important to consult the manufacturer's instructions and local building codes before installing any type of plastic pipe.

Question 5

How tight should plastic pipe fittings be?

Accepted Answer

Plastic pipe fittings should be tightened until they are snug, but not over-tightened. Over-tightening can cause the fitting to crack or break, leading to leaks. It is important to follow the manufacturer's instructions and use the appropriate tools to ensure a proper and secure fit.
