My 1.6g Briggs toilets have a conventional ball-cock. The larger internal seal in one of the valves was deteriorating so I replaced with a universal adjustable height ballcock valve. The new valve has the standard adjustments - a large nylon screw on top of the valve shaft, and brass screw that adjusts the stopping point of the lift arm (fulcrum).
I've been adjusting these two screws ad nauseaum over the last two days and I'm unable to get the valve to remain full closed. When I flush the toilet, the water fills to the appropriate level and shuts off 99.9%. But a tiny flow remains through the bowl fill tube, and the flow gets larger over time. The level in the tank doesn't change. If I tap the valve with my finger, or slightly lift the float arm, it shuts off completely. It's almost as if the valve requires slightly more force to fully shut than the buoyancy of the float can provide. On the other hand, I have no clue what the proper procedure is for adjusting the valve. Any suggestions?
