The flapper valve apparatus and method of use provides a flapper valve that is basic and easily installed on the pins of a toilet reservoir overflow tube. The apparatus has sufficient flexibility to allow flexing of the arms and ears for easy installation. The apparatus provides water volume conservation by seating the lower bulb within the valve seat prior to substantial drainage of the reservoir. And, a user can vary the amount of water used in a flush by varying flush handle hold time.
