How to stop your toilet running

Posted by Adam Chard in DIY Advice | 3 months ago 4 min read

Does your current toilet run constantly? If so, you could literally be flushing both water and cash straight down the drain. So, what can you do to fix it?

When you reach out to flush the toilet you rarely give it a second thought, expecting it to wash through with water as you get on with your day. However, just like any other system it can sometimes be prone to experiencing problems, such as a running toilet. If you are unsure why this happens and want to know how to fix a toilet that keeps running, we explain everything you need to know below.


What is a running toilet?

A running toilet is one that continues to operate and flush through water even when it is not being used. This is usually caused by a faulty part that can be replaced, although it may also create some stress in the meantime. It can lead to a lot of water being wasted as it continues to run and can even lead to higher utility bills if not fixed quickly. The good news is that it can be fixed by those with a good amount of DIY experience or a qualified plumber.

How to stop your toilet running

A running toilet is usually caused by 1 of 4 problems:

Faulty chain or flapper

If water is not being held or refilling in the tank there is a good chance there is a problem with the flapper. The flapper is a rubber or plastic cap that works to ensure water remains in the tank and will need to be replaced if this is causing the issue.

In many cases, old flappers become hard and are no longer able to provide an adequate seal, allowing water to continue to pass down into the bowl. If the flapper feels hard, rather than soft, then it won’t be offering the protection needed to create the seal and will need to be replaced. To fix this issue, buy a replacement at a DIY store and then attach it to the chain and pins in the tank.

Water-logged float

There can also be instances where water becomes trapped inside the float. This makes the float heavier so it sits lower in the water, which opens up the float valve, allowing water to constantly run through. Some floats may need to be unscrewed before you can check them and once you have done this shake it to check if any water is inside. If so, the float will need to be replaced with a new one.

Water level is too high

Inside the tank is an overflow tube that stops the tank from taking in too much water. However, if the float is sitting too high it could lead to water seeping into the overflow tube and down into the bowl. This will trigger the fill valve and start the process to fill up the tank, which will then happen on loop.

To resolve this issue lower the float setting on the fill valve. If you a valve with a metal rod you can adjust the clip and float to a lower position. For systems that feature a rod and ball, slowly bend the middle of the rod and the ball should also lower as a result. Test the new level by flushing the toilet and checking the water level once complete, which should be about an inch away from the top of the tube. If more adjustments are needed, flush and check again.

Refill tube is too long

If the refill tube is too long and hasn’t been positioned correctly in the overflow tube, this could be the reason for the running toilet.

This requires you to shorten the refill tube, which can be done by first taking it out of the overflow. Hold the tube just above the opening and trim off that small section. When putting it back inside, to ensure it remains in place and doesn’t move around, clip it to the side of the overflow tube so it keep it secure.
