ABSTRACT:
A handle assembly for providing dual flush functionality to a flush valve. The handle assembly comprising a handle and a plunger engagable with each other. The plunger axially slidable in a bush disposed between the handle and the flush valve. The bushing having a passage for receiving the plunger. The plunger having a first and a second axis along which the plunger may travel through the passage. Movement of the handle moves the plunger from first axis to the second axis wherein actuation of the flush valve by the plunger along the first axis results in a different flush volume than actuation along the second axis.
