How long does CPVC pipe last?
Chlorinated polyvinyl chloride (CPVC) pipe is a thermoplastic created by the chlorination of polyvinyl chloride (PVC) resin. It has been available since the mid-1960s, and has an estimated lifespan of 50 to 80 years, with an average of 70 years. Because it a more recent product, the durability of the material will be better defined over the next few decades.
CPVC is cream color when new and tends to darken towards tan as it ages. It has many of the same properties as PVC pipe, except that CPVC is also heat resistant to approximately 200º F, which is a property that PVC lacks.
Here’s a graph that compares the life expectancy of CPVC pipe to other types of commonly used residential plumbing pipes.
