Making the choice between PEX or CPVC pipe depends on a number of factors. This natural immunity means a CPVC system can withstand chlorinated water at the temperatures and pressures where PEX will fail. Also, PEX is susceptible to oxidative degradation and embrittlement when exposed to hot chlorinated water, while CPVC isn’t susceptible to attack by chlorinated water. In addition, third-party research has found that CPVC installs about 15% faster than PEX in its most common configuration. Copper pipes are metal and more durable, while PEX, PVC, and CPVC pipes are plastic and tend to have a shorter lifespan. This means it won't leach chemicals even if they have been sitting inside the pipe for a long period of time. PEX is a flexible plastic material made from medium- or high-density polyethylene.

This can cause leaks or allow heat to escape, meaning affected areas might not thaw. PEX — Cross-linked Polyethylene. While the PEX tubing may carry a temperature and pressure rating of 100psi at 180°F, the pipe is not listed to perform under those conditions in the presence of chlorinated water. 2004. PEX, like polybutylene, is a European technology that is less resistant to water conditions and chlorination commonly found in the United States. It is made by melting high-density polyethylene and extruding it into the form of a tube. It is made from high-density polyethylene that has cross-linked bonds in the polymer structure. While a FlowGuard Gold plumbing system will never fail under normal use due to chlorine levels, ASTM F2023 is required to determine a time-to-failure for PEX systems under normal use conditions with chlorinated water. Not only are PEX fittings more expensive, but even when properly assembled, they can result in joints that have been the subject of several high … CVPC pipe is made of thermoplastic and is used in sprinkler and drain lines as well as water‐based heating systems.
