Abstract
A dual flush flapper valve apparatus for converting a standard toilet to a dual flush system includes a valve body having a lower rim and an upper rim. The lower rim is configured to selectively engage a tank valve of a toilet. A valve top is coupled to the valve body and is selectively engageable with the upper rim to seal and alternatively unseal a top aperture. A first chain and a second chain are configured to attach to a trip lever of the toilet to move the valve top between a closed position. The first chain and the second chain are arranged such that a partial depression of a handle of the toilet lifts the trip lever to move the valve top to the open position and a full depression of the handle lifts the trip lever further to move the valve body to the lifted position.
