Abstract: A dual volume flushing system for flush tank comprises two flapper valves located adjacent to one another. An abutting tongue is provided between the two valves for preventing the lower valve to interfere with the action of the upper valve. A flush handle is provided to simultaneously actuate both flapper valves in order to allow the water in the flush tank to rush through the valve body in the direction of the toilet bowl to allow the use of a minimal amount of water. The flush handle is also provided with a two system lever to separately actuate the upper flapper valve alone when only liquid material needs to be flushed from the toilet bowl.
