All About Pipe
Chlorinated Polyvinyl Chloride (CPVC)

This type of plastic pipe has excellent chemical and fire resistance characteristics.

It is crush resistant, with high-impact and tensile strength; it is also nontoxic. It functions at 180° F in pressure systems and at still higher temperatures in low and non-pressure systems.

CPVC does require special solvent cement, however, and cannot use the same cement as other types of plastic.

It is used in hot and cold water-supply systems and hot and cold chemical-distribution systems when metal pipe cannot be used.

This material is similar to PVC, but it is better for handling corrosive water at temperatures 40 to 60 degrees F above the limits for other vinyl plastics.

Although this type of pipe was developed to handle hot water, the manufacturer's stress and temperature limitations should be checked before installing. Local plumbing codes should be consulted also.
