    The PVC pipe broke at the joint between the 1" supply line and the primary valve right at the end of the threaded copper pipe. Do I replace the threaded copper end or how do you remove the threaded pvc from the copper?

    Is the threaded copper a female adapter? If so, it might quicker and easier just to cut the adapter off, sweat a new one on and not even attempt to remove the broken PVC. To remove it, you'd have to make a couple of cuts in the PVC then pry the pieces out. You'd mess the copper threads up to a certain extent doing this which could make it difficult to get a leak free connection, and you'd not make very good wages saving the cost of a new adapter.

    New Adapter

    The copper fitting is female. So just grab a torch, take it off and add a new one? Any special considerations for solder, gas ??

    95/5 tin/antimony solder, Oatey No. 95 tinning flux, and a propane torch will work fine.

    Very good cleaning is important.

    Leave the copper alone, and remove the plastic piece from the female adapter. There are several pipe removers that will work.

    You can always melt the remaining PVC and pry it out of the fitting.

    Used the torch to remove the female fitting. It came off easily and so did the PVC which was quite soft. Reattached the fitting. Will be testing the system today. Thanks

    How did you reconnect the pvc to the copper? Not with another male PVC adapter, I hope.

    I quit using PVC male adapters a long time ago. If you need to make a connection to female Iron or copper pipe. Cut a Pipe Nipple in half and use a coupling to join half to the PVC. You will have a joint that is twice a strong...

    A PVC male adapter might as well be perforated at the bottom the the threads.
