Check the little rubber tube that goes into the overflow pipe. If it does not end above or just below the top of the overflow pipe, then that is your leak. Cut it off and secure it above the overflow, preferably using the plastic clip that came with the valve.

: I have a hidden leak in my commode water tank. Over the past two years, I have replace the flush valve with flapper at least four times thinking that for some reason water was going under the flapper. Today I installed another new flush valve with flapper and filled the tank. I cut the water supply. The water level dropped about two gallons in three hours. Any suggestion of how this water is leaving the tank and down the drain. All new seals were also installed. Thanks to anyone for a suggestion.
