How to solder copper pipe in the real world. Not on some vice on the desk but under it. In a hard to reach position. How to use flux and clean pipe, solder and a torch. How to use a heat matt and a cooling rag to make a water tight seal.


I was going to do a simple video on how to solder copper pipe So firstly what we need is some flux a brush and a cloth A blow torch you’re not going to get anywhere without your blow torch and some pipe cleaner and some solder this is lead free for potable water
so first things first we’re going to get a little fitting out so the simplest fitting there is a little Tee like that. First thing i’m going to show you is how to prepare the pipe. So the first thing we do before we continue is clean the pipe give it a little run round with your cleaner so once thats nice and clean we can put some flux on it. You get some flux on your brush, and put that nicely over the cleaned area.
I recommend you try and get some in the end of the fitting as well so we can see at the moment there’s nothing in there so try and get some in the end of the fitting. Then push the piece you’ve cleaned Into the fitting you’ve got push them together
Now that piece is ready to solder.
I’ll do the same on the other side and out of the bottom.
Now we get our blow torch, light it up and adjust it down as it’s only 15 mm pipe to a really nice soft setting now apply the flame nice and lightly to the copper fitting that means our nozzle is about one inch away from the copper fitting. Now once it gets nice and warm
try and heat it up all the way around and then
once you think it’s hot enough just touch the solder and that will run nicely into the fitting. Pop the flame underneath as well. make sure it get’s all around the fitting.
We’ll do exactly the same at this end now. Heat that fitting up nice and evenly until you think you can get the solder to run into the fitting. So we warm this fitting up here
for this lower one as these can be tricky sometimes. Everytime you touch the
solder wire to the fitting itself take the flame away and then try and suck it into the fitting just like that Sometime when you’ve finished soldering a copper fitting, give it a paint with some flux especially if it’s still hot, that’ll clean the copper fitting down. A really important thing to remember
is to get your wet rag and wipe the excess flux off otherwise it will go green and horrible.
make sure the pipe is nice and cool and give it a wipe
So there we go we have a nice, clean, non wastful soldered fitting there. clean, non wastful soldered fitting there. Nice 15 mm solder. So that is nice and easy but what about in the real world? You don’t have a vice on the desk in the real world will be doing soldering like this
in a place like this HERE, that’s were you’ll be. You’ll be doing this sort of thing
because you can’t get round to the other part of the pipe. You’ll getting the pipe you’ll be going
Ahhh, trying to get it all clean
wondering why did I take this job up? You’ll only be able to get your flux round
one side of the pipe, because you can’t get to the other side because it’s
against a wall or something and then you’ll be getting
your copper fitting and fluxing it becuase if it doesn’t get all around
it ain’t gonna solder brother. The pipes might not go together. You’ll have to pull them out and push them back in
You’ll go Oh my god I need to get my heat matt in here but it
doesn’t want to stay up or something. You’ll get to the point of grabbing an old bit of pipe
to hole your heat mat in position We can’t heat it all up so we’ve got to put the flame up
a little bit more sometimes there’s even a little bit of water in the pipe that you weren’t able to get rid of so you heat it up more. Sometime you have to pull the pipe down so you can get some of that water out if there’s any in there only once you’ve done all that can you run your solder in just like so. So really are any of the other soldering videos out there on the internet realistic?
