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.
