Hi, Any ideas to simplify getting the broken PVC flange off the PVC pipe... I have broken off the collar portion, can see the joint, was primed & glued as supposed to be... collar is insert style. I have made 5 cuts with hacksaw through the collar stem, tried to force a wedge (screwdriver) between the two pipe walls. Needless to say, this has not been simple so far... any help much appreciated!
