For those of you who use CPVC piping in new homes and older construction:

Do you think that the piping in a structure being in a closed system, meaning a pressure reducing valve on the main...do you think CPVC has a greater ability to allow thermal expansion,

and do you think that if it does...is it detrimental to the longevity of the piping.?

I constantly see homes piped in CPVC that have a check valve, no sign or symptoms of thermal expansion issues.

CPVC is not a favorite of mine it seems like it get brittle on the hot side and cracks at the fittings a lot and then when you cut it back it just shatters and a one foot repair turns into a six foot repair,then it takes hours for the glue to cure on the hot side .Never considered thermal expansion on it,justif the heating and cooling effects of the water didn't age the pipe faster than expected and/or changed the molecular compisition of the pipe.
