How to Stop a Toilet From Running

Is your toilet running? No this isn’t the start of a bad joke.

A running toilet is just one of those minor inconveniences that come with being a homeowner. There are lots of things that can cause your toilet to run too long—or worse—constantly. That’s why deciphering what is causing your toilet to run is so important.

How to Fix a Toilet That Won’t Stop Running in 4 Steps

Fortunately, uncovering the reason why your toilet is running is relatively simple, and so is the toilet repair. Read on to learn the four easy steps you can take to stop your toilet from running.

Step 1. Test the Flapper

All you have to do is push down on the flapper with a stick (yes, like a popsicle stick) when you hear the water running. Listen closely to the running water. If you hear the running water stop then you know the flapper isn’t sealing properly. Replace the flapper (you can get these at your local hardware store) if so.

Step 2. Inspect the Fill Valve for Leaks

Once you have tested the flapper, the next step is to inspect the fill valve for leaks. To do this, flush the toilet and look for a fill valve leak. Hold the float arm and lift it up when the tank is filling to see if the water stops. If the float arms needs adjusted, adjust it so it stops the water level when it is ½ an inch or one inch below the top of the toilet’s overflow pipe. Replace the valve if it continues to leak after this.

Step 3. Replace the Old Fill Valve

This step is simple. All you need to do is turn off the water supply, flush your toilet, and use a sponge to soak up the remaining water from the tank. Disconnect the water supply valve, remove the full valve locknut and remove the old fill valve.

To install the new fill valve, refer to the instructions sheet that comes with the replacement. Typically, you will want to tighten the locknut a half turn past hand tight.

Step 4. Connect the Fill Tube

The final step to stopping your toilet from running is to attach the new fill tube to the fill valve nipple. Attach the other end of the fill valve to the enclosed angle adapter and finally, clip the angle adapter to the overflow pipe.
