In a water closet comprising a toilet bowl and a toilet tank, including a water filling valve and an overflow tube coupled toy the tank, and a buoyant flush stopper seated in a discharge opening in the tank, said stopper being operated by a flush lever connected thereto upon actuation of a flush lever; a dual flush system for said toilet tank, to select a full or partial flush volume of water from said tank, comprising: a latching plate coupled to said tube, having a latching aperture and a tilting gate pivotally mounted to said plate for closing and opening said aperture, said plate being connected to said lever to assume an open position with said lever in a first position; a secondary buoyant float having two vertical parallel beams coupled thereto, defining a slide slot between them, a slide shoe coupled to a beam retained by the overflow tube, so that the secondary buoyant float is slidably guided by the parallel beams through the shoe in response to changes of water level in the toilet tank, the secondary buoyant float also having a latch member coupled thereto, said latch member being adapted to pass through the latching aperture of the latching plate and be retained by the tilting gate for a total discharge of the tank when flushing solids, by operation of the flush lever to a first position which lifts only the stopper; and, a shoe rod coupled to the secondary buoyant float, so as to push the stopper from a floating to a seated position to discharge a partial volume of water, by operation of the flush lever to a second position which lifts the tilting gate and releases the latch member from the latching plate and allows the buoyant float to descend in response to the level of water in said toilet tank, thus pushing said shoe rod against the stopper to interrupt the flush.
