CPVC to Polybutylene
Posted by Rick on May 09, 2002 at 10:37:05:
My 1993 house was outfitted with a Vanguard Manobloc (point to point) Polybutylene system. I'm installing some new plumbing using CPVC pipe. Can I attach the CPVC to the main Manobloc distribution assembly? There are some spare ports and I have found a CPVC adaptor with a rubber washer that screws onto the Manobloc unit. My options are to rig up a small test pipe, install it on the Manobolc and see if it holds or to tee off of the copper pipes and use CPVC to copper transition adaptors. Any advise on this unique situation? Thanks for your time.
