Where can I use CPVC?

Copper tube size (CTS) CPVC is designed for use in hot-and-cold water distribution systems. CPVC systems are ideal for all potable water piping requirements in typical residential (single and multi-family), motel/hotel, mobile home, manufactured housing, light commercial, and institutional structures.

What is the thermal expansion rate for CPVC and how can I allow for expansion and contraction when installing?

CPVC piping will expand about 4 inches per 100 feet with a 100°F temperature change.

Additional information can be found on PPFA website. CPVC Installation Handbook


What is the difference between IPS and CTS polyethylene?
