A flapper valve assembly for regulating the passage of water from a toilet tank is provided with a structure to reduce overflow risk. There is a yoke pivotally disposed in the tank and supporting a flapper seal that can be seated on and unseated from the flush opening. A flapper arm has a first segment coupled to the yoke along a pivot axis and a second segment extending away from the pivot axis toward the flapper seal. The flapper arm is configured such that it delays seating of the flapper seal when the water in the tank is above a predetermined level and assists seating of the flapper seal when the water is below a designated level.
