Hi Mike, Let me give some info to my readers on both PEX and CPVC. PEX Tubing and CPVC water pipe are generally cheaper than copper piping.
PEX is a water supply piping system that doesn’t corrode or develop pinhole leaks, is chlorine-resistant, scale-resistant, and has fewer fittings, connections, and elbows than rigid plastic and metallic pipe.
PEX is excellent for radiant heating...continued
