Question

How do I remove a soldered on copper end cap so that I might extend the system?

Answer 1

you have to remove the water from the line first . do this by cutting it a little before the cap .then clean the pipe ,flux put new fitting on and heat it up and solder

Answer 2

If you have enough excess pipe, after shutting the water off and draining the system, cut the old cap off with a copper tubing cutter and the just start adding to you existing system. Or you can sweat the old fitting and solder off and then go from there.

Answer 3

You want to cut the cap off. If you remove it by using a propane/map gas torch, you'll have to spend some extra time cleaning the pipe end of all old solder. Your new weld will have more of a chance of failing, opposed to cutting it and starting with a clean end.. Good luck.

Answer 4

cut it off

Answer 5

Turn water off, let it drain by opening all the faucets, hose bibs and propane torch it off, or just pipe cut it off.

Answer 6

If you have room just cut it off with a tubing cutter. If not it will require a minimum of a propane torch, drain the water from the pipe and just heat the the pipe close to the cap and use a s***w driver to gently tap the cap off. Have some water on hand if close to flammable materials.
