Abstract: A flush valve system is constructed of a single housing having at least two inlets fluidly connecting a single outlet. Preferably, the system includes a flush handle assembly having at least two handles mechanically connected to and at least two linkages. Both linkages pass through a sleeve assembly, which mounts in the standard mount hole provided on conventional gravity flush toilet tanks to provide effective control for the dual inlet flush valve. The inlets are sealed with a primary and a secondary flapper valve that are preferably connected by a chain or other link to the at least two linkages. This system permits the user to conserve water by selective flushing of a large or small volume of water.
