I stand corrected. It just came out of my memory and I should have
checked again. It is chemically modified and probably breaks down
differently with aging.

Plumbers have told us that copper pipes age faster with our well water
and I had thought about CPVC and PEX as alternatives. One neighbor got
CPVC and I heard about his breakage problem. Another got PEX and the
fittings started to leak. I have not had a leak in the copper for 20
years. Lessons to learn to all in group considering use of a new
material in the home where long life is needed.

Plastic installers are better these days and the termination system
used with PEX has fixed those leaks.
I am not sure about what you get at Home Depot but a real plumber
crimps a ferrule on that PEX that is not coming apart.
CPVC has been the standard down here for 30 years with a pretty good
track record. Lots of copper has pin holed and was replaced in that
time.
