what's wrong with the toilet that runs
Take a few minutes to figure out why you have a run-on toilet, and then you can repair it. You have a run-on toilet if each flush doesnât end with a gurgle but instead continues with a hissing sound, with water running into the toilet bowl. To find the source of the trouble, remove the toilet tank top and place it in a safe location. Then push the flush lever and watch what happens. Donât worry about the water in the toilet tank â itâs clean. Run-on toilets are usually caused by a problem with the tankball, the ballcock or intake valve, or the floatball.
When the rubber flapper is compromised, it allows water to run out of the drain causing the toilet to constantly refill. Replacing it is easy--replacements are available at most hardware stores or home centers. Be sure to take the old one with you to find a correctly matching replacement.
