The neck pipe for my shower was made of plastic - I say "was" because it just snapped off this past weekend. The problem is the plastic snapped right where it threaded into the brass pipe inside the wall, so there's nothing to grip to back the broken piece out of the threads. Worse yet, the pipe dope the PO (previous owner) used is so solid and dried that it's as though the two pipes have bonded to each other even though they're made of different materials.
I'm at a loss as to what to use to back this little piece out of the brass pipe. Anyone have experience with this?
