Broken bathtub drain - PVC near slab
During replacing a bathtub, the drain pipe got caugt on the tub and it broke the PCV joint near the slab. The coupling broke, but the PCV piece that comes in through the slab fully intact. However, it is still glued into half of the coupling. There does not appear to be enough room to cut and simply put a new coupling on (although if that is the only way, then it may be possible). Is there some way to cut/heat/?? The coupling off, leaving the PVC piece in tact.
