Abstract
Abstract A controller for arbitrarily determining the amount of water from a tank which passes into a toilet bowl makes use of a stop for the flushing handle in one handle position for holding the flexible valve at a location lifted from the tank outlet such that water can flow from the tank but which when released will immediately close the outlet. The handle however is shiftable to a second handle position wherein the flexible valve is lifted to full flush position in which the entire contents of the tank is discharged.
