DIY Plumbing | How To Stop A Running Toilet

It’s the middle of the night and you can’t sleep, why? Because you can hear your toilet running. A running toilet is a common problem that many households will experience at some point or another. As frustrating as it may be you can resolve this issue with only a few inexpensive parts from your local hardware store and about 15-20 minutes of work. The ability to do it yourself will help you save water and in turn, save money.

This image can help if you are not familiar with the parts inside of your toilet. We’ll be using the numbers on this chart later so that you can easily know what we’re talking about.

how to stop a running toilet

Inspect Your Fill Tube

The fill tube (number 5 on image) is responsible for spraying water down the overflow tube and refill the bowl after each flush. If the fill tube falls off it won’t make your toilet run constantly, but it will make your flushes much less powerful. Make sure the fill tube is firmly secured to the outlet on the fill valve and the overflow tube to avoid this.

Make Adjustments to Your Float Height

The float in our image above (number 1) is a ball type float. If your toilet has one of these you can set the water height by bending the rod up or down until it shuts off the fill valve at the correct water level. If your toilet has a circular, black, plastic part connected to the stem of the fill valve then there will be a clip and rod on the side that you use to adjust the water level. Now that you know where your float is and how to adjust look at the back wall of your toilet’s tank and find the required water fill line. Mark the level on the overflow tube with a permanent marker so that it easier to see and judge if the water level is correct. Make adjustments to the float until the water level fills to mark after each flush. It’s important to do this because if your float is set too high water will continually fill the tank, pour into the overflow tube, and into the bowl creating that dreaded running water noise.

Adjust Your Flapper Chain

If your flapper chain (number 9 on image) is too short or is tangled it will hold the flapper (number 6 on image) open and continually dump water into the tank. Make an adjustment to the flapper chain so that there is only slight slack when the handle is up. A chain that is too long could also be a problem because it won’t allow the flapper to open all the way and let the proper amount of water into the bowl.

Replace The Flapper

If you’ve tried all the steps above and your toilet is still running then your flapper (number 6 on image) is likely worn out. Be sure to shut off the water supply to your toilet and remove the flapper. Take note of the brand and model of your toilet before you go to a hardware store because many flappers will have specific compatible toilets listed on the package. If you are unable to find one that is listed as being compatible with the toilet in your home then look for a universal one that closely resembles the one that you pulled off your toilet. Flappers usually clip onto the base of your overflow tube or have a ring on the end them that slip over the top of the overflow tube.
