I didn't realize it was more expensive, guess I lucked out. CPVC was standard and free but copper was a 2500 upgrade.Ted Glenney said:Well it's great to have it, but unless you just have a bunch of money to burn I'm not sure why you would put it in. But to each his own, I'm sure you and your plumber will both be happy.
I am told to use cpvc for intake and exhaust for a Locnivar Domestic water heater. Is there a distinct advantage for using one over the other?CPVC will flow up to 200 degrees F through it, what are you using it for? What sort of differences are you specifically interested in?
