Can anyone recommend a good way to loosen and remove a 2" drain pipe from a cast iron fitting? I am concerned about harming the cast iron fitting. I was wondering what I could do to help free it up before putting pressure on it. Heat would be my last option. Would WD40 or something similar help to free it?

If you do not want to burn out the lead (caulk) joint Try the following get a Sawzall cut the galvanized pipe about 2" away from the caulked join.

Then get a LENOX blade for metal and cut the piece of pipe inside the hub in TWO PLACES and using a cold chisel gently knock out the cut section being very careful not to let it fall into the drainage line.

THEN Cave in the galvanized section sort of folding it in from each opening by the slit you made then pull out the piece.

Using the same cold chisel you can now cut the lead and remove it then pour a new joint using oakum and molten lead BUT Becareful

You could also cut the pipe 2" or 3" away from the hub and use a MISSION cap this way you have another cleanout OR buy a No Hub coupling NOT Fernco and then install what you wanted to this pipe

Thanks. As I got closer to the drain pipe and trap, I realized that only the drain itself had lead caulking, which led me to believe that I was dealing with C.I. My apologies for the error.

It turns out that the pipe that I want to remove, which appears to be galvanized, is threaded into the trap. I was able to remove the drain itself, but I could still use any tips for loosening and removing the threaded pipe and trap. Thank you again.

Normally the trap is brass or chrome plated brass and not ferrous metals thus trying to remove a ferrous nipple (galvanized) from the trap I find is more time consuming then just replacing both
