Adjustable toilet flapper valve assembly

A toilet flapper valve assembly comprising:

• a flapper;
• a cone mounted to the flapper, the cone and flapper defining a cavity, the cone having a first port and a second port, the first and second ports fluidly communicating the cavity with an exterior of the cone;
• an adjustment dial rotatably mounted relative to the flapper for rotation about an axis of rotation, the adjustment dial having a first flow adjustment region that cooperates with the first port for regulating flow therethrough and a second flow adjustment region that cooperates with the second port for regulating flow therethrough, the first and second flow adjustment regions fixed to one another such that rotation of the adjustment dial about the axis of rotation simultaneously rotates both the first and second flow adjustment regions about the axis of rotation relative to the first and second ports;
• the first flow adjustment region including a first flow region that extends angularly about the axis of rotation, the first flow region having a first portion that increases in dimension when moving angularly in a first direction about the axis of rotation to vary a degree of exposure of the first port to fluid communication with the exterior of the cone;
• and
• the second flow adjustment region includes at least one second flow adjustment region flow aperture and at least one imperforate region adjacent the at least one second flow adjustment region flow aperture.
