I have purchased a home that still has the old gray polybutelyne plumbing system.
I will eventually change out the entire piping sytem as I am well aware as to the problems with this kind of pipe. Thats a no brainer there and was a factor in purchasing this home.
My question is, as my experience with Copper, PVC, CPVC and PEX is okay, can I use a PEX crimp ring and fittings/valves on Polybutelyne as a temporary fix? (6 months to a year). I am really not familiar with PolyBute.
I am installing a new dishwasher and given I dont have much room to work in and I dont like the idea of a standard screw ring/compression feeder valves for the fix.
Do not use standard pex fitting on the PB. They sell a tranxition fitting (coupling ) from PEX to PB. It has a standard black crimp ring for the PEX side and a copper colored crimp ring for the PB side. Use your standard PEX crimper on both rings. The big box stores carry the fitting (comes packed with the correct crimp rings).
