For many years, copper was the gold-standard for water supply pipes, as galvanized steel fell from favor. Copper plumbing pipes can last for up to 50 years, but as it ages, copper thins out, eventually leading to pinhole leaks. More recently, various forms of plastic have replaced copper as the favorite, though copper pipes and fittings are still widely available. Due to the price of copper and longer labor needed to install, many builders have switched to alternative water distribution piping, especially PEX.

What is CPVC pipe?
The acronym CPVC stands for chlorinated polyvinyl chloride. It is often (but not always) a cream-colored or off-white plastic. This type of pipe can stand temperatures up to about 180 degrees Fahrenheit or so (this depends on the schedule), so it can be used for both hot and cold water lines. CPVC is the same outside diameter as copper and PEX, so the same push-fit fittings used for PEX and copper, such as SharkBite, will also fit the CPVC piping.
What is PVC used for?
Historically, PVC was one of the first forms of plastic used instead of copper for water supply pipes. PVC is normally used for cold water pipes only, as heat can eventually break down the plastic.
