CPVC can handle 200° Fahrenheit. CPVC is a thermoplastic made via chlorination of the polyvinyl chloride resin. It is resistant to degradation and provides a long service lifespan. In fact, the first piping systems using CPVC occurred in 1959, and they are still working without a problem.
Copper pipe conducts heat well, so the pipes get warm during exposure to hot water and stay warm. This helps keep hot water at a consistent temperature as it travels through the house.
CPVC piping is better than copper.
The reason is because CPVC is completely 100% corrosion resistant. No matter how much water that pipe is surrounded by, it’s not going to wear away or corrode. The same can not be said of copper. Most suitable for commercial applications, hot water distribution.
Copper tends to pit, scale, and form pin-holes due to corrosion, and this corrosion can also lead to increased levels of copper in your drinking water.
Better to go with the CPVC.
