Why the fill valve keeps running?
A chain that’s too short or tangled won’t allow the flapper to close and water will continue to leak into the bowl. This causes the fill valve to cycle on and off to refill the tank. A chain that’s too long, or a flush rod that hits the tank lid, won’t open the flapper wide enough to stay open for the full flush.

In the vast majority of cases, the problem is with the flapper, which is the rubber seal between the tank and the bowl. When it’s worn, or the chain is too short, water seeps into the bowl, and the fill valve cycles on as soon as the float falls below the cutoff level.
Why does my toilet randomly run for a few seconds?
