leaky flapper, overflow pipe, bad fill valve, wrong pipe height adjustment, wrong water level and more. There are many reasons your toilet may cause trouble. So, this is the most important job to inspect the whole toilet system carefully first and then take steps to fix the toilet. Make sure that you stop the running toilet before start inspecting and remove the water lines before starting repairing.
Test the Flapper:
You must check the flapper first as it’s the most common cause of running toilet problem. If you find the toilet is causing trouble for the flapper, it’s time to replace the flapper. Remove the lid of the toilet’s water tank and look inside for the flapper. Once you get it and find the flapper isn’t working properly it’s time to replace the flapper.
- When you hear the water running, push down on the flapper to stop it with a stick. Once it’s stopped, replace the flapper and check the length of the fill tube. Keep it 1/2-1 inch above the waterline.
- Adjust it by cutting if needed. Replace the flapper if it isn’t sealing properly.
- You should check and clean the flapper after a period of time in order to ensure better performance.
Check the Fill Valve to Fix Running Toilet
- To check the fill valve for a leak, flush the toilet and look. If you find a leak then lift up on the toilet float arm. Do it when the tank is filling. If you see the water stops then adjust of bend the toilet float arm so that the tank stops filling when the level of the water is half to an inch below the top of the toilet’s overflow pipe. If the problem continues then you should replace the fill valve as soon as possible.
- To remove the old toilet fill valve, turn the water supply off and flush the toilet. Then sponge the remaining water from the water tank and disconnect the water supply line. After then, unscrew the lockout of the fill valve and lift it out to remove.
- To install a new fill valve, insert the new fill valve into the tank according to the instructions sheet and then tighten the locknut a half past turn tight. The overflow pipe may still be higher than the critical level; even if the new fill valve is at its maximum height. Cut the overflow pipe with a hacksaw and shorten it to the adjustable mark. It should be an inch lower than the critical water level mark of the fill valve.
- Now, attach the fill valve nipple to an end of the new fill valve and attach another end to the enclosed angle adapter. If you feel necessary, shorten the tube to avoid kinks. Then clip the angle adapter with the overflow pipe and finish the installation by attaching the flapper chain to the flush lever of your toilet. Finally, turn the water supply on and flush your toilet to check if everything is OK. Please note that you may need Hacksaw and Pliers for this job.

Adjusting Water Level:
When the flapper or fill valve isn’t the cause of the running toilet, you must check the water level then. It’s another common cause. When the water level is too high, the water drains into the overflow tube constantly. Fix it as soon as possible.
- Check the water if it keeps draining into the tube. If it does, lower the float to adjust the water level.
- Determine the float type you’re using in your toilet. There are mainly 2 types of float that are used commonly in the toilets. But they work as same. The float ball fill valve has a long arm that is attached to fill valve and there is a rubber ball-shaped float at the end. Shake the float and if you find water inside it; replace the float.
- On the top of the fill valve, you’ll find a screw attaching float arm. You can adjust the height of the float by turning the screw with a screwdriver. Adjust it to the right level and flush the toilet to let the tank to be refilled. Check the water level to be sure if it’s working properly.
- Check the fill tube if your toilet runs intermittently. The fill tube should be above the waterline always. If it isn’t, it leads to intermittent running. Make sure that the tube isn’t submerged when the tank is full. Simply trim enough of the tube so that the tube sits above the water line if the tube dips into the water.
