Ok, that's a good pps file. Exactly the problem I'm having.
I see that it says that I shouldn't have used male CPVC into female
copper and tells why. I was told to do it that way because the
water pressure pushing out on the female
edges could break it. Guess I was told wrong.

Should I just reverse it and use a female CPVC with gasket around a
male copper fitting?

Or should I use the socket x metal thread where the CPVC is factory
molded into a copper fitting?

Which do you think would be best?

Again, thanks.

The Powerpoint description 'Avid Hiker' gave shows that
it's supposed to be done exactly opposite to what you describe.
A male threaded copper into a female CPVC, containing the ring
at the bottoming out point.
