Is there any type of fitting/connector to connect CPVC cold water line to PVC?

-Chuck

Chuck, I’m not sure if that type of fitting/connector exists or if those pipe types are at all compatible. Gluing a MIP adaptor (Male Iron Pipe Adapter, which has male pipe threads and will adapt to PVC and a few other types of pipe to make a transition from threaded pipe to a type other than threaded) on each end and then using a union might do the trick, but I would recommend checking the manufacturer’s website or contacting them.

The water draining from my central air conditioning is causing the PVC pipe to reverberate with a thump, thump, thump as it drips into the sink.  I have been told it is cold water sludge build up in the pipes.  I have tried cleaning the pipes with hot water and bleach with no success.  Any suggestions?

-Don

Don, the PVC pipe thumping/reverberation is probably starting at the unit and being transmitted down the pipe. It’s only a drain with nothing in or on it that could actually create a noise or vibration. I recommend you call a company that services central air units; they should be able to diagnose.
