No one has used the bathroom for a while, yet the toilet suddenly starts filling up like it was recently flushed. To more superstitious folks, it might seem like the bathroom is haunted. For us, it sounds like the problem is the water level in the tank.
Why Does My Toilet Keep Randomly Filling?
When you flush the toilet, several things happen at once. You pull a lever which lifts a flap inside the tank. This flap covers the channel that takes water from the tank to the bowl. When it’s lifted, all of the water gushes down to the bowl and into the drainage pipe, and then the flap closes to seal the tank once more. A float in the tank controls a valve, which lets water back into the tank after you flush. When enough water fills the tank and the float rises into place, it shuts the valve off.
This is all usually over in less than a minute if everything works correctly. If a toilet fills randomly and empties without flushing, it is in need of a quick fix or repair. If you hear your toilet tank continue to fill for a long time after you flush, a couple things may be wrong.

Identifying the Problem
1. First, make sure that the shut-off valve to your toilet is opened all the way so enough water can get to the tank to fill it up properly.
2. Open the tank and see if the flap is positioned correctly. If it isn’t, place it securely over the hole.
3. Check to see if your float is stuck, keeping the valve open. If there is something obstructing your float or stopping it from rising, correct the situation. Your float and valve mechanism may also need to be to be adjusted so the valve shuts off at a slightly lower water level.
If Those Checks Fail…
If the tank randomly starts filling by itself, it’s a sign that the flap is failing. This means it’s not properly covering the hole to the tank and is allowing water to escape, which in turn causes the water level to drop.
If the tank is filling up past where it should be, the pressure could cause even a brand new flap to fail. But if the water level is normal and the flap still isn’t able to seal the tank, replacement is the best course of action.
