ABSTRACT:
A flush valve diaphragm is provided. The diaphragm includes at least two by-passes orifices. Each by-pass orifice in the diaphragm has a by-pass associated therewith. Each by-pass having a passage therethrough, allows communication with the control chamber above the diaphragm with an inlet chamber below the diaphragm. The diaphragm also integrates the function of locating and providing sealing means to the flush valve system's aux valve mechanism.
