working on a kitchen reno and got too zealous in cutting some old PVC from a cast iron stub, so now there may not be enough “lip” on the old connection to put a new PVC coupler for a 1.5″ pvc pipe. Problem is the old PVC transition piece is nice and stuck onto the cast iron.
What would be the best way to remove it so I can either attached a new pvc couple or a Fernco onto it (right now the fernco onto the small PVC piece leaks at the joint)
Here’s a picture for reference – https://imgur.com/a/R35c9P4 – first picture has the plumbing setup and the 2nd is what the stub looks like.

A heat gun will soften it enough that you should be able to get it out.
Thanks! I will try that out when I get back.
Heat up the PVC pipe with a heat gun so that the joint can be softened enough to separate the pipes. You can also use sandpaper
