Episode 5 of the Wash Basin Install Videos. This one shows you how to install your hot and cold water pipes safely and easily. The pipes are 15mm copper tube. This also includes the installation of two compression fitting isolation valves. For more information visit http://www.plumberparts.co.uk
Right, so under our sink, as I said earlier on, we’ve got our 2 hot and cold water pipes, our waste pipe, the waste coming out of the bottom of the sink and our 2 hot and cold flows to the taps. What we’re gonna do in this video is connect these 2 pipes here to these 2 pipes there.and we’re also going to put 2 isolation valves in because it’s best practice. If there’s ever a problem with the tap there’s 2 isolation valves for the home owner or anyone like that to switch it off and then call a plumber out if they’ve got any problems. Before we do anything to these we’ve got to go and isolate them. If you don’t know where to do that or if they’re in the loft or anything like that, go downstairs and turn the main isolator off. Then run all your hot and cold taps until they all stop running and only then, when they’ve stopped running, you know that all the pipes are empty. At that point you can cut into the pipe here and cut these off They’re going to make a little bit of a hissing noise because water is going to go down that’s trapped in this pipe down to the taps below that I’ve opened up. So let’s give them a little wee twist, a little wee twist, twist. Twisting.There we go. Keep twisting round. There you go. Keep on going. You’ll get the same thing. You’ll see it’s just cutting a small score in there right now. That’s sucking as well. Just let it suck before you take it fully off. So it’s stopped hissing. There you go. Now the next thing we do is we clean these 2 ends up with some emery cloth because soldered pipe loves to be clean. Give them a nice clean. Get them really so there’s no paint on there at all. It takes a little while but persevere as it really does pay off this does. Once they’re nice and clean coat each one in flux ready for soldering.
So, we’ve got our 2 elbow fittings here. One on here like that and now what you want to do is solder 2 small stubs on Get your copper pipe cut a small stub of about an inch and a half maybe 2 inches, flux around the end and put it on there like that. Now we’re ready to do our first 2 solders. I’m experienced at doing this obviously so it’s easier for me. But if you’re not happy get yourself a heat mat wet it, make sure you’ve got a little tub of water nearby or something like that so if you do find any catches alight you’ve got something to quickly put it out. Also when you do any soldering always make sure you do it at least half an hour before you intend to leave the premises or leave your house, or something like that Just so you know for sure that there’s no smoldering or anything like that that could eventually turn into a fire. Another tip about soldering you don’t need to have a burning flame like that. Just a nice light flame for 15mm pipe is good enough. It’s easier to control as well and you’ll feel a lot more relaxed doing it yourself Reel off yourself a nice long bit of solder and just pop it under your fitting like so and just warm the fitting up nice and even. It will take time but it’s well worth doing like this. Soldering is all about being patient. There you go. So that’s the first one done. Move onto the second. Now just wait a few seconds Often I’ll get my flux brush again and just paint around here to clean the fitting up a bit. After that you give it a wipe with a damp cloth and that will really clean the fitting up. If you leave any flux on the fitting it does tend to go green and it will look horrible in about a month’s time. So, best to get all the flux off now while you can, while it’s a bit warm. Once those 2 stubs of pipe have dried nicely, get our 2 check valves and pop them on. Make a note of the arrow direction and which way the water flow’s going to be push on each valve, and tighten them up. If you want to know how to tighten up compression fittings visit one of our other videos as we’ve done one on that. As soon as you’ve installed them correctly it’s best just to turn them off now. so that the slot is across the line of the pipe like that. What I’m going to do now is just finish off all the soldering, get the pipe put back together and get the actual tap connected up. Now all being well you’ve tightened up both nuts, all your solder joints are fine. They’ve cooled down and you’ve cleaned them off. You can hopefully now turn the water back on and test them but don’t run too much into the tap basin yet as we haven’t got the waste on. That’s what we’re going to be doing in the next video.
