You are much better off cutting out the joint or the section you're
working with and then solder new copper pipe in its place.

well, I tend to agree, but it really depends on the existing
configuration and location. In this instance, zero possibility
of a fire, but cutting back further is more of a hassle.

Then it's just a matter of applying enough heat to melt the solder.

You will need to remove every last drop of water in the pipe, or you'll
never be able to apply enough heat to melt the solder.

If you can or if you need to, shove some rags or paper towels in the
pipe to soak up the water and then remove them.

Maybe drill a small hole right at the joint so water can drain out.


Standard plumbing trick is to wad up a slice or two of white bread into dough and shove it into the pipe up stream from the joint. This is helpful when you can't remove the blockage after the soldering is done. It will liquify and you can flush it out. ** Don't use "healthy" bread - use plain soft white bread, no whole grains or seeds, and tear off the crust.

Is your problem getting the pipes disconnected?

Or are you asking how to re-connect or clean the surfaces once you've
got them apart? The answer to that is sand paper.
