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 doesn’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. Don’t worry about the water in the toilet tank — it’s clean. Run-on toilets are usually caused by a problem with the tankball, the ballcock or intake valve, or the floatball.
Apparently, there are several factors that may result to a running toilet. It could be a sticky flush valve, a malfunctioning flapper valve, problems with the floatball or ballcock issues. And you know what, each of these require a different way of getting fixed up. So the principle is to first find the real cause of the problem and then provide the right solution afterwards.
