1. What are the differences between CPVC and PVC?

The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing, and therefore, failing of the plumbing system.

4. CPVC and PVC Properties

Both resist corrosion and degradation from chemicals classified as an acid, alkali, or inorganic material.

PVC maximum functional temperature is 140° Fahrenheit.

CPVC maximum functional temperature is 200° Fahrenheit.

The extra chlorine in CPVC increases chemical strength and helps prevent bacteria / biofilm formation within the pipes.

Both are impact-resistant and durable.

Both are safe for use with potable water when ANSI / NSF 61 certified.
