This is just for copper this can be used to glue copper pipe together so you
don't need to solder it you can use this. I did actually make a video using this
several years ago and I have used this a couple of times to get me out of some
very sticky situations and it worked very well. A few people have commented
saying that it's no good so what I'm going to do is I'm going to
make up a joint and then tomorrow we're going to pressure test it using the
pressure testing equipment. The instructions for this are quite specific
and they do say that you need to clean the copper pipe using 60 grit abrasive paper like so,
which we're going to use, but I'm going to use this end feed
fitting and we're going to make a joint and then tomorrow after 24 hours have past
we will pressure test it and see if it can withstand the pressure. To start off
with I want to take the 60 grit abrasive paper and I'm going to use that to
clean up the end of the copper tube.
Once you clean that up there is no need to blow it you can actually leave the
residue on there and that will help with the bonding process. I'll now clean the
other piece up.
Then finally I'll clean inside of the fitting.
Now I've done that I want to give the Just for Copper a really good shake.
I'm then going to take that and
I'm going to apply a really thin zigzag bead on the inside of the fitting.
I'm going to take the copper tube and we'll do exactly the same with that.
Once I have done that I'm going to push it into the fitting
and I'm going to turn it 360 degrees within five seconds. I am now going to repeat that
process on the other side of the fitting.
So this time I'm going to grip the fitting and I'm going to push that pipe in
there and then I'm going to twist it 360 degrees within five seconds. I am
going to take that and wipe off the excess.
Then we'll leave
that until tomorrow. It's now being 24 hours and that is the joint that we made
yesterday. I have now connected this up to the pressure testing rig and at the end there
I have put a washing machine tap and then we can bleed out the water. So I'm just going to
pump the machine now so we get water coming out at the end. Now we've got
water there I'm just going to close the tap. So I will now lift that up so that it's near the dial so
you can watch the dial at the same time. I'm not
going to start to pressurize the pipe.
And you can see that straight away we've gone up to ten bar and there's no sign at
all of the joint leaking. We are losing a bit of pressure from the compression
joint on the corner because there's a second hand joint. So you can see that
the joint is still holding. You get it up to 20 bar. See there's no sign at all
of the joints leaking. So twenty bars is approx. 290 psi and you can see
that that joint is not leaking at all so I'm just going to take it up a little
bit further.....
As you can see we are now over 30 bar which is well over what kind of pressure
you will expect to get in any domestic property. We're now at 40 bar and the joint
is still holding it hasn't failed at all. So for those people that say that
Just for Copper doesn't work and that it's a lot of rubbish obviously some
people have never used it or they have used it incorrectly. If you prepare the
joint as recommended by the manufacturer and follow their instructions you can
see that the joint is perfectly suitable for domestic plumbing. That's actually
holding a lot more pressure than what you would get in a domestic situation. At
this house we have approximately 90 to 100 psi of pressure. As you can see we've
got 30 to 40 bar there which is well over 450 psi. I hope you have enjoyed
