ABSTRACT:
An inner tank or reservoir is mounted in the conventional flush tank of a sanitary toilet or commode. The tank may be rectangular and have an open top and a closed bottom. An outlet in a vertical wall is closable by a buoyant sphere. The sphere may be free-floating and guided to the outlet by a cage. Alternatively the sphere may be lever-mounted and pivotable in and out of sealing contact with the outlet. A bellows operated from an air pump displaces the sphere from closed relationship to the outlet. Preferably the pump is exterior of the toilet flush tank and connected to the bellows by a flexible plastic conduit.
The conventional tank is flushable in conventional manner from its outside handle and the capacity of the inner tank may be added to the water flow by the operation of the air pump.
