How to UNSOLDER copper fittings, SUPER EASY! | GOT2LEARN


Welcome back guys to another plumbing
video! All right so why would you want to unsolder a joint rather than cutting it
off? Here are a couple of reasons. The most common reason why one would un
solder a fitting is to save it. Fittings can go up in cost quite quickly
and knowing this skill is a must in order to be a qualified plumber.
Another reason is last-minute changes could be made and a modification is
needed to complete the job and lastly a, lack of space. In some cases, a soldered
fitting will be too close to the wall to cut, the better thing to do here is the
unsolder and resolder your new fitting after. If you already have your new
fitting ready to install, here are the procedures to unsolder and reconnect it
in one go. The first thing you want to do is ensure that the water supply is off,
then you’ll need to find a way to get the excess water in the pipe out by any
means. If you have a drain cock nearby use it to drain the system, if you don’t
just cut the pipe when you’re sure the water’s been drained, get your torch and
let’s start un-soldering but first if you don’t have the new fitting that’ll
be replacing the old one continue on, but if you do have it,
make sure to prep it before un soldering the old one as you’ll be
installing it right after removing the old one. If you aren’t sure how to solder,
go check out my “how to solder” video it has clear instructions on how to make a
leak free connection. If you’re reusing an old fitting that has leftover solder
in it, here’s a cool trick that will aid you in installing it. Instead of using
sandpaper to remove any excess solder in the fitting, get yourself an
appropriate size wire brush and cut the tip off. You can now use your new tool
in a drill to speed up the process. Alright so start heating the fitting and
use a pair of adjustable pliers to wiggle it off. A little tip here is to
remove your pliers from the fitting as you’re heating, they’ll absorb the heat
and make the process twice as long to complete. When the fitting starts to want
to wiggle its way off, grab your prepped fitting, swap it with the one you just
removed and solder it and you’re done! If you guys have any questions feel free to

  1. Another good one. I don't think I've tossed a fitting in 40 years. Sound cheap but it has saved me a lot of trip to the hardware store when I have a problem. Even short sections of straight pipe comes in handy.

  2. thank god you use CANADIAN MADE (in toronto) DAHL. valves. thats all i use for my bathroom installs. I hate brasscraft. lates

  3. I've unsoldered plenty of copper fittings but am on a job right now in close quarters at a hotel and I want to unsolder some 1 1/4" copper out of a brass 1 1/4" ball valve. Feeling a little hesitant man, what say you?

  4. I like to wipe the old pipe off with a dry rag or some toilet paper while the solder is still in liquid form. Then you can start with a solder free pipe and clean it and flux it properly.

  5. Do you preheat the new fitting? It looks in the video like you are putting a new cold fitting right onto the pipe after removing the old fitting. I assume you heat it some more and add more solder?

  6. I noticed that he attached the new prepped fitting to the old unprepped pipe. Is this normal, effective? Is it ok to do this without prepping (cleaning/fluxing) the old pipe beforehand?
