I want to install a new sink which I have and the plumbing does not match up. I need to remove some of the pcp plumbing in order to make it fit. Ok so now how do I do that.
I tried and didn't move.
Heat gun?
How do I break that seal to remove and reinstall new fittings.
Thanks

Granboar: I assume you have PVC or ABS (plastic) tubular drains under your sink now. They may be glued together or attached with nuts. If nuts, then unscrew them by hand. If glued together - then cut them and re-glue. Here you may need few new fittings...

Can you post a photo of you undersink plumbing ? It would be a great help !

I think you meant PVC instead of pcp. Right? You cut glued fittings out. You can't separate glued fittings. They're welded together. What I do when I'm faced with this problem is cut the old stuff back to the wall stubout and run everything new. Or is there a problem I don't know about? Regards, Tom
