How To Fix A Running Toilet

I'm going to show you how to fix a running toilet, guaranteed.

And I’m going to do it right now. I’m Roger Wakefield lead APV expert plumber. I’ve been plumbing over 38 years and I have every master endorsement in the state of Texas. And this chapel I’ve teaching you everything you need to know about plumbing. If you haven’t been here before, please subscribe. So you don’t miss anything. This is a great toilet that we’ve got. We’ve cut up in the back. So I’m going to be able to show you how to do things that maybe you probably couldn’t see before, because somebody is trying to shine a light in the top of the camera and the top. We’ve cut open the back of this and I’ll show you in a minute. But the very first thing you want to do is shut the water off.

So you've probably got an angle stop coming out from under your toilet

This is a quarter turn stops. You just turn it a quarter of a turn. Now, if this was an old style angle, stop that you have to screw him, turn it off and slowly disconnect the water right up here. You want to make sure that the water shuts off. The last thing you want to do is connect this hose and realize the water didn’t shut off. Now you’ve got water spraying everywhere. You’re trying to put it all back together. So check your angle. Stop. Make sure it shut off and then get ready to work on the toilet. First thing I’m going to do is take the lid off, set it out of the way. That way it’s safe. We don’t want to drop it and break it and crack it or anything like that.

As you can see, we've cut the back out of this toilet

As you can see, we’ve cut the back out of this toilet to help show you what it is we’re working on. So we took the angle stop. We shut the water off. We’re going to put a towel down under here, and we’re going to loosen this up to take apart the supply line. Now, whenever you take it apart, you’re going to get a little bit of water to come out. And this is just the water that’s in the fill valve. So you can either pull the hose over out of the way, disconnect it from the angle stop. But you want to make sure that it’s not in your way. Whenever you’ve got a toilet running, it’s a couple of different things. It could either be the flapper is letting water through and that’s going to let water continue to go through the fill valve to fill up.

You're going to do is check the flapper

So, first thing you’re going to do is check the flapper. You want to look at it and you want to see the rim on it and see if the flush valve has any cracks or Nicks or anything like that. If so, you’re going to need to change the flush valve. Now that’s a completely separate video. This one here is really how to stop your toilet from running. So normally it’s either going to be the flapper or the fill valve. Now, remember I told you earlier, check the seal on the flush valve to see if it’s good, but to change a flapper. A lot of times it’s just unhook it And unconnected from the handle. There’s not a lot to them and they’re not very expensive. I do tell people to check and make sure that you’re getting one that was designed for your toilet. So say that you have a replacement. It’s really easy

It'll flush properly

To just snap it right back into place and always make sure that it comes up to where it touches the top. That way you’ll know that when it’s full of water, it’ll flush properly. Now the fill valve, you can literally disconnect the screw and what this does, this adjust the water level on your float to make your fill valve, stop filling. Once you get it apart, lift it and turn it and take it apart. You want to check your diaphragm from valve and what you do is literally pull it apart. There’s a little screw and a little pin in here. You want to see it for, as they needed to bring in here will not tell people is rinse this off. Really good. If you need to wash it with soapy water, but rinse it out really good and look down in here and see if you have any trash in here.

This diaphragm valve will fix your problem

A lot of times, just this diaphragm valve will fix your problem. Now, one thing that you can do is if you see any trash down in here, hook your hose back up, crack your angle, stop back on just barely and let it flush this out. Any trash down in here will be pushed up in here. Now you may want to put her rag or put your hand over it to keep anything from happening, but sometimes just flushing that out can solve your problem after you rent it. Like I said, you’ve got a little pin in here, like a needle. You want to make sure that everything goes right back together. Just like it came apart. And once you get it put together, you’re going to lift up. Got it right back where it goes and turn it. And you’ve rebuilt your fill valve. Now, if this does not work, you’ll end up changing your fill valve. Now changing these out really. Isn’t hard to do if you’ve already got the water drained out of here, which if you’ve checked your flapper, you’ve already got it down to this level. You can take a wet vac or a big sponge and get the rest of the water out. But if changing that diaphragm, Val does not make your fill valve stop running. All you need to do is take the nut apart on bottom.

Changing out this fill valve is not very hard to do

Keep your towel under here because when you pull that up, any moisture down on the bottom is going to come out. Changing out this fill valve is not very hard to do. And remember we took it apart while ago. All that does is snap right back together. If you had to change this out, it’s easy to do at this point. If all you did is work on the diaphragm valve, remember lift and turn it all comes apart very easily. Now, when you’re putting the new one back in, if this one has been working great, I always tell people, look, adjust it for the same hot cause you already know that works. Make sure your rubber washer is on the bottom. Slide it back in where it goes. Snug. You’re not up. Put your fill tube in and everything’s ready to go check here. You want to make sure that when this comes up, this is about a half inch to an inch below your overflow. Now that you’ve got everything done, take your angle, stop hook your supply line back up.

We are almost near the end of how to fix a running toilet.

Turn the water back on

Make sure you snug it up. So it doesn’t leak. Turn the water back on. And the water’s going to come out back here at the bottom. It slowly gonna come up and it’s gonna fill up till it reaches the proper water level. And then it’ll stop. Be really careful putting the tank lid back on. You want to make sure to not drop it and break it. This porcelain will crack and will break very easily. Cause if you hadn’t done so please subscribe to our channel and give us a thumbs up. If you like this video, if you’ve had to rebuild a toilet yourself and you’ve learned how to do it, let us know. Was it really this easy? Cause we think it is. And as you say, I only used a couple of tools here. Really? I think I just used the channel locks. This is not a very hard job to do. And it’s one that you can do and save yourself some money. I’m Roger Wakefield lead AP the expert plumber. I’ll see you on the next video. If you don’t get flushed.
