ABSTRACT:
A dual flush system for a toilet tank, to choice a desired flush volume of water from said tank to flush solids or liquids, depending on the operation of a two-position flush lever, comprising: a latching plate coupled to the overflow tube, having a latching aperture and a tilting gate connected to the flush lever mechanism; a secondary buoyant float slide retained by the overflow tube, having a latch member coupled thereto and connected to the flush lever, passing through the aperture of the latching plate; and a shoe rod coupled to said secondary buoyant float to push the stopper when it is discharging a first volume of water to flush liquids from the toilet bowl. For flushing solids, the flush lever is operated to a first intermediate position, lifting only the stopper causing a total flush of water because the latch member is latched by the tilting gate of the latch plate and the buoyant float as well as the shoe rod remain inoperative. When flushing liquids, the flush lever is operated to a second position lifting the tilting gate loosing the latch member allowing the secondary buoyant float to fall down together with the shoe rod to push the stopper impeding a total discharge of water.
