CPVC

The acronym CPVC stands for chlorinated polyvinyl chloride. It is often (but not always) 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.

According to the International Association of Certified Home Inspectors (InterNACHI), CPVC and PVC pipes generally last for 50 to 80 years under perfect conditions, though early failure is also reported in some circumstances.

As with PVC, you should use primer and glue when making a CPVC joint. Also, make sure the glue specifies that is can be used on CPVC.
