Plumbing – How to remove a brass pipe that has been jammed into a larger iron pipe

drainsplumbing

I was replacing the sink this afternoon when I noticed that the p-trap would not reach the drain pipe. No biggie, right? I'll just buy some extensions from the local big box and be on my way.

I attempt to take off the drain pipe so I can fit an extension on and what I can see appears to be someone who took a 1.25" pipe, shoved it into the 1.5" hole (with the threads "holding it in") and then tightening everything up.

Now, I'm trying to unscrew this mess (literally) and I can't get the pipe out of the 1.5" drain. I'm wondering if I should try to heat up the system with an acetylene torch to try to make everything a bit more pliable or if I've got no other choice than to get a plumber to come and rerun the drain in the back of the wall.

The input of this community would be most appreciated.

I'd slip a cheater bar into the drain and see if you can pop it loose by turning it clockwise (so you don't unscrew the tail-piece). If you can get it to turn without twisting it you should be able to get it to pull out. If you can't and it starts to twist the pipe without breaking it loose, cut it off with a hacksaw close to the tail-piece leaving enough of outside to grab with a pair of vise-grips. Then take a hacksaw blade and carefully cut through the pipe from the inside. You should then be able to use a vise-grip or pliers roll it in to a smaller diameter and pull out the last bit.
