ABSTRACT:
A demand type flush tank control for saving water by controlling and limiting the motion of the water release valve of the water storage tank of a toilet, such that the water release valve can be moved only a sufficient distance to bring about the amount of flushing action required in a given instance, thus preventing the entire content of the tank from being used except if actually needed. My novel control or restraint type device prevents a bulb type water release valve from becoming free floating, but rather compels it to reside closely beside its seat during a flushing operation, or in the case of a flapper type valve, my restraint serves to limit its movement. These advantages may be accomplished by the use of a restraint device involving either a one piece or a multipiece construction. As should be apparent, the operative position, in accordance with this invention, for either the bulb type or the flapper type water release valve is such that it readily returns to its seat as soon as the toilet handle is released, thereby effecting a daily savings of many gallons of water.
