Word, and welcome to this plumberparts.co.uk video. This is the last video of this particular set of episodes, all about how to install a wash basin. If you want to know anything about the previous things, go back through the videos, and you’ll see them there. This particular bit is about installing the waste. It’s the last part, so let’s get all that done, and hopefully have it running by the end of the video.
Right, so here’s our outlet waste, here. We’ve got a pop-in waste that we did earlier. We’ve got all our pipes in that we did earlier. Our two valves, and here’s the waste outlet, here. Let’s first have a look at the sealing components of the trap. This is known as a P-trap. So the sealing part here, you’ve got a rubber ring, and that seals on the bottom of this metal thread, here. But it also sits around the collar, in there. Generally, you aren’t to take this off, but I’m only doing it for demonstration purposes. So that will sit up on there like that, and seal really well on there.
On this end, we’ve got the compression fitting end. And how this works, is you have a slip collar. When you’re tightening up this nut, if this slip collar wasn’t here, it would drag on this rubber bit here, which is the bit that causes the seal. So the slip collar goes in there, the rubber flat seal goes in there, your part will go in and around that inner circle, around there, like that. The seal sits round in there like that, and that’s where it causes a seal. The slip collar goes on there, the nut goes on there. And that tightens up, and causes a great seal.
A few of the other things, I’m actually gonna glue things, today, and solvent weld once, alright? If you want to know how to use those, go back to our video page, and we’ve got a video up there for you on how to use solvent weld fittings for waste.
So, the first bit we’re gonna do here, anyway, is attach this P-trap, and then we’ve got a rough idea if the bit’s a part we need to cut, and where to put our elbows and stuff to match these two up together. So, let’s pop that up on there. Let’s get that in there like that. Alright, so, what we’re gonna need here, to get this bit done, is two elbows. So, we’ll have one elbow popped on there like that, and we’ll need another one put in here about there. So what I need to do now is cut my pipes to length, glue them in. Get them so they’re popping into
this compression fitting here, tighten that up, wait five minutes for the solvent weld to go off, and then, hopefully, I can turn these two valves on and test for leaks.
Right, are you ready? Are you set? We’re gonna turn it on, and see if it works. No leaks, so far. Oh, yeah! Turn it all the way around. Nice and hot. Cold. Yeah! Pull this old boy, is it up or down? Push it down, oh yeah. There we go. No leaks down here. Nothing at all.
We shut the pipe, and now we test this overflow. It’s gonna over the flow. And that would mean we’re testing our plumber’s mate that we did a few videos ago. It’s feeding it nicely. That’s great. Well, as you can see, all is well. So there you go, it’s all done. The basin, hot works fine, all the waste draining really well, switch over to the two. Nice little mixed tap. Our pop-up waste works well, all of that bit. And it’s all done. I am so happy.
