I hear the water come on by itself. Is there something wrong with my meter?

The meter is okay.

The problem is a flapper valve leak in a toilet. When the flapper valve leaks it allows the water to slowly drain out of the tank on the back of the toilet, which causes the water to come on to refill the tank. If you suspect a flapper valve leak, a simple way to determine whether you actually have one is to take the top off of the tank and put some food coloring in the tank. Let the toilet sit for a while, sometimes this might take a couple of hours if you have a small leak, and then look to see if the food coloring appears in the bowl without flushing it. If it does, then you definitely have a flapper valve leak. This type of leak may be intermittent but usually once a flapper valve starts leaking it only gets worse and should be replaced.
