A two stage toilet tank bowl control system includes a tank ball selectively positioned on the valve seat in the water tank. The tank ball is linked to a lifting lever so as to raise the tank ball from the seat when the lifting lever is rotated in its flushing direction. An air outlet tube communicates with the interior of the tank ball to permit air to be exhausted from the interior of the tank ball. The air tube communicates with a passageway in a air flow block mounted to the wall of the water tank. The passageway has a full flush branch and a partial flush branch. A partial flush valve maintains the partial flush branch closed during conditions of full flush. A full flush handle moves the lifting lever in its flushing direction with the partial flush valve maintained in a closing condition against the outlet of the partial flush branch. A partial flush handle moves the lifting lever in its flushing direction in such a manner as to remove the partial flush valve from the partial flush branch outlet so that air is purged at a greater flow rate from the tank ball under partial flush conditions than under full flush conditions to return the tank ball to its closing position on the valve seat in a shorter period of time than under full flush conditions.
