Help! Can't desolder old pipe

It isn't brass.


two things : One already mentioned above if there is any water in the piping at all, the heat will draw the water toward the joint, and it won't get hot enough.


If you OVER heat the fitting, it's almost like you can't even see the solder turn soft, the pipe will expand inside the fitting, and it will never come out.

This will give you the opportunity to install a cleanout and a trap. Your wife will love you, and of course you will have the opportunity to easily clean out the pipe should your wife decide to put something untowards down the drain (don't ask me how I know about this particular issue). By the way, you can sell the copper for scrap at $2.50 a lb and make back most of the cost of the project.
Where would you suggest installing the cleanout and trap? Pictures of what you recommend would be great!

You stated that you were using a "blowtorch". A bit more specifics as to what type of "blowtorch" you were using. It would be possible that your torch would not heat this joint hot enough. I have had situations where a small LP gas torch would not get the joint hot enough and had to change to MAP gas.

Just cut it somewhere between the second and third picture, giving yourself room to rebuild back with whatever you choose. Don't cut the elbow, cut away from it far enough to couple to the old pipe and get another elbow in place.
