What is causing my toilet to fill up on its own?
Asked May 6, 2013, 06:35 PM
The toilet in my master bedroom intermittently begins to fill on it's own, as if the tank hasn't drained all the way. It happens long after the toilet has been flushed, and can happen at least 10-20 times per day. There is not much water in the toilet to begin with, and when it fills on it's own, it only runs for about 3-4 seconds, but I can see and hear the water running. There are no leaks that I can feel or see. Any suggestions or thoughts?
