copper pipes

Copper tubing is most often used for heating systems and as a refrigerant line in HVAC systems. Copper tubing is slowly being replaced by PEX tubing in hot and cold water applications. There are two basic types of copper tubing, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, pressed connection, or solder. Copper offers a high level of corrosion resistance but is becoming very costly.

I exposed the pipe by removing a ~30cm section of the plastic sleeve and a ~10 cm section of the pipe around the hole. Several...

    How would you replace this kitchen tap mixer?

    I need to replace my kitchen tap and these are the existing pipes - any suggestions? I was going to cut just above the connection with a pipe slice, install the new tap with flexi pipes and then connect it up with compression fittings/PTFE tape. Does that sound sensible?! Thanks.

    Plumbing Newbie - Replacing Copper Pipes
