Toilet flushing apparatus to provide either a partial or full flush. A drain extending down to the toilet bowl has an upper and a lower inlet located at different levels in the water holding tank. Upper and lower valves seated in the inlets are operable to release water from the toilet tank into the drain. The lower valve can be opened to provide a full flush, but when only the upper valve is opened a smaller quantity of water is released to provide a partial flush to conserve water.
