ABSTRACT:
An improved flushing means is disclosed for use in water tanks such as are for flushing toilets. The flushing means has a water inlet with an improved two-stage valve using inlet line pressure for operating the two stages. A float is movably mounted on the inlet for controlling the valve with a lever operatively coupling the float to the first stage of the valve. A cooperating vertical hollow and floating overflow tube including an adjustable bowl filling siphon controls the tank discharge to the bowl. These improvements to the tank discharge to the bowl are also to be incorporated into the commonly used flapper-type flush valve.
