    Toilet loosing water

    I have an AS one piece Hamilton toilet that keeps loosing water(fill valve opens 3 times in 24 hours.) I have changed flapper, however, it still wants to fill by itself.

    Have you put food coloring in the tank to see if the flapper isn't 100% tight. Even with a new flapper the seat that it sets on might ha e small crack or built up not letting the flapper to seat properly.

    Agree with servicefitter - place one of those dye tablets in while the tank is really calm and you will easily see where the leak is. I had one once where the porcelain itself had a flaw and the flapper valve wasn't the issue. A little bit of plumber's putty solved that one.
