ABSTRACT:
A flush valve diaphragm of a flush valve includes a body having a segmented insert within a flexible body portion and a central passageway. The body further includes a peripheral sealing portion with the flexible body portion within the peripheral sealing portion. The peripheral sealing portion can include an integral filter, an exit chamber and a bypass arrangement, such that water flowing through the filter flows through the bypass arrangement. The integral filter version will retard clogging of the bypass arrangement. The segmented insert includes a plurality of trapezoidal members with outward protrusions. The plurality of trapezoidal members are connected to each other on their outermost edge by a runner.
