Abstract
A pair of lever arms each have an intermediate segment configured for pivotal mounting on a pair of pins that support a corresponding end of a pair of mounting arms of a flapper valve. Each of the lever arms has a forward end configured to engage and provide a lifting force on a corresponding one of the flapper valve mounting arms when the lever arm and the flapper valve mounting arm are rotated in a first direction during opening of the flapper valve upon manual actuation of a flush control lever or button. A counterweight reservoir is connected to a pair of rearward ends of the lever arms for holding a volume of water and delays rotation of the flapper valve in a reverse direction to seal the flush valve until a volume of water has drained through an outlet aperture in a bottom portion of the counterweight reservoir.
