We just replaced the our Toto Toilet Fill Valve. We got the right one after calling Toto. I was also told they are universal. After putting the new valve on and adjusting the fill #'s to what the other valve was marked at.
(we could not find the model # anywhere. Was not inside the tank as they said it should be so we went by the old valve) The toilet is filling continuously by itself. Can anyone tell me what we need to do. We put the valve height at the lowest number. We could not find where to adjust the refill ratio key setting. It would also help if anyone knows where the model # might be?
