I re-plumbed most of my basement about a year ago with CPVC and it has held up well. Up until now, I have been able to go around the existing galvanized supply lines without touching them but I finally have to cut into them due to a bathroom remodel.
I've read many times that the way to get into these pipes is to cut into them with a recip. saw and then use 2 pipe wrenches (one in each direction) to remove the pipe from the fitting. Looking at the threads where the pipe and fitting come together, there seems to be some corrosion or old hardned pipe dope or something other than clean threads.
If I manage to back this pipe out of it's fitting, what are my chances of being able to use the threads in the fitting again? The fitting that I need to work is a tee which is part of a riser going to the 2nd floor. If this fitting does not seal properly, I'm looking at tearing into many walls and floors to find a place to re-attach.
