Abstract: Dual flush toilets save water by allowing the user flushing to evacuate liquid wastes to use a smaller volume of water from the toilet tank than is necessary for solid waste evacuation. The Invention described in this Patent Application restricts the dual flush functionality to a retrofittable handle. This handle produces a full flush by means of a timer activated by rotation of the handle to the large volume position. In rotating the handle to the large flush position a mechanical timer is wound and causes a retractable latch to project and hold the flush arm in its upward position for the period dictated by the timer. Upon release of the arm the flapper returns to seal the tank allowing for recharge with a fresh supply of water. If the small volume position is selected with the flush handle then the smaller volume of flush water as limited by the flush chain float position will be released.
