Claim:
In combination: a water storage tank having a bottom, a peripheral sidewall, a discharge port and a supply port in the bottom; a ballcock valve mounted in the supply port, said ballcock valve including workings for passing or stopping flow of water, a float responsive to water level in the tank to which said workings are responsive, an inlet to the workings, and a tank refill line and a bowl refill line from the valve workings; a valve seat around said discharge port; a closure adapted to open and to close said valve seat, said closure comprising a hollow body having a central axis and a dimension of axial length, an upper neck, a lower guide, and an enlargement between said neck and said guide, said neck and guide being coaxial, a lower surface on said enlargement facing said valve seat so disposed and arranged as to fully engage and close said seat with said lower guide extending below said seat, the neck, guide, and enlargement forming a passage open from the upper end of the closure to its lower end, said refill line discharging into said upper neck; an engagement on said upper neck laterally spaced from said central axis; a handle rotatably mounted to said sidewall; and a rigid lever attached to said handle for rotation by said lever, said lever and engagement being operatively associated with one another, laterally spaced from said central axis, whereby actuation of said handle results in an off-axis upward pull on the engagement tending both to tilt and raise the closure off of the valve seat.
