Hold tight and welcome to today’s Plumberparts.co.uk video. My name is James and today we’re gonna be having a look at a very very simple problem you can get with your toilet, especially if it’s a push-button one like the little one that we’ve got in the background here. What can happen is sometimes you can press the push-button flush on your toilet, 0it can be one of those nice little remote push-button flushes, the ones that are just on top of the cistern, that look a little bit like this one here. Then once you’ve pressed it, everything comes out the cistern, then it just keeps on tricklin’ in. Now, we’re gonna show you very quickly how one of these work, using our lovely little fake system we’ve got in the background here, and then we’re also gonna show you how very quickly to fix this problem cause it’s so easy to fix. Alright, I hope you enjoy the video and remember to subscribe. Hold tight!
So let’s first here have a quick look at the flush unit we’ve got here itself. A closer look at these, they’re really, really easy to install in the first place. They got a nice little rubber seal underneath and there’s a big nut that goes up underneath the system that holds that on and makes the right water-tight seal. You can also have a lot of these have adjustments for how much you want to flush, how much you want to go through. The other slight difference you can have with two different types of push-button flush-unit are you can have the fixed-button one like here. You’ve got your half-flush and your full-flush, and you have two little rods that go down onto the button from the cistern cap and they can go on there or the cistern lid. Or, you can have one that has a remote cable that goes off to a button elsewhere like in a bit of woodwork or something like that. They’re really popular as well cause they’re so versatile.
So if you look here, when we push this up you’ll see there that that little paddle lifts up like so, and lifts up like so as well on both those buttons. Now, we have different heights of float here that when the water gets down to a certain level that’ll activate the flow and also close the flush, okay? Now the thing is sometimes the main problem you can actually have is that the water-flow going into the cistern is so high and so fast that the water-level never really gets down far enough to actually allow the float to activate and shut the valve off. And it kind of holds the valve up like so, just like that.
So the first thing I do is pop the lid off, press the button and have a look, and actually see if the amount of water going into the system from the fill valve is so much that it’s not actually allowing it to fully empty, it’s kind of beating the water going into the toilet and flushing away. So have a look at that first. If that is the case, you’ll see a small pipe underneath, just like this one here, and that will have a small valve on it like so. You’ve got a cross on the valve just here, at the moment that’s in the off position, if that is in the inline position like so it’s fully open as you can just see there. So what you often want to do is basically half-close it and try and strangle down the amount of water going into the toilet cistern. That is usually the problem and that’s the quickest way of sorting it out. So easy to do. The other thing you can do with these to see if there’s a problem, is sometimes you can actually pull off this top flush piece just like so, like that. This bit will stay in the toilet this is where the water comes out of, we don’t need that for this bit now. I’m just gonna plop that down. We’re interested in this piece here, okay.
This is the damper that moves up and down. Now, as you can see on the bottom there, we’ve got a nice little rubber seal. And what can happen is, is the rubber can get old. Sometimes it can actually sort of mould itself in the up position, it doesn’t actually quite seal properly. You can buy rubber seal replacements for these in most the plumber supplies in the U.K. They’re really, really easy just to pull off and pop another one on,and often that will sort your problem out.
The other problem you can have is, when you put this back together, and we take a close look here, we can see that this has to sit down on this seat.
