A flush control apparatus includes a housing which replaces the usual tank top and has a chain extending down to the usual outlet valve member which is weighted to give it negative buoyancy. In the housing is a lever, motor, switch and timing circuit system which operates in response to actuation of one of two push buttons to lift the valve member for a predetermined interval of time, thereby determining an amount of flush water to be dispensed into the bowl.
