While trying to remove shower base pipe broken thread got stuck in to receiving copper pipe. How to remove broken threads from copper pipe so we can install new pipe.
if it was me...
I would try heating the remain pipe with a torch then putting ice on the inside..
then try to unscrew the remaining copper pipe..
try cutting the copper pipe with a saw. gently. more to score it then cut thru..
then pry the copper towards the insides..then unscrew.
if that fails..open the wall up and replace the pipe..
Buy an "internal pipe wrench"....or open the wall and redo it.
