Warren,

You are lucky to still be alive. Plastic pipe violates code and is
VERY dangerous when used with compressed gasses, including air. If you
get a crack in the pipe , you will have a CPVC hand grenade. I have
seen PVC pipe go 200 feet and shatter the windshield of a car when
being pressure tested with air. CPVC is even more dangerous than PVC
when used as air lines. Change the PVC to copper or steel and save
your own life.
