Why does my toilet keep filling every few minutes?
Why does my toilet keep filling every few minutes? If your toilet keeps refilling at 15-minute intervals, it probably has a leak. In the vast majority of cases, the problem is with the flapper, which is the rubber seal between the tank and the bowl. It should be still, but if the flapper is leaking, you'll probably see ripples caused by water flowing from the tank. What to do if your toilet tank fills every 15 minutes? Turn the water back on and let the tank fill. If the leaking appears to have stopped, you don't have to do anything...
