ABSTRACT OF THE DISCLOSURE A flush valve assembly (10) for a water closet having a reservoir tank (12) with a discharge opening (15). The flush valve assembly (10) incorporates a spud (13) having a tubular body portion (14) which presents an annular groove (55) that extends peripherally of the body portion (14) in close proximity to its axially upper rim (88). The tubular body portion (14) is received in the discharge opening (15) of the tank (12). The radial groove (55) supports a cantilevered diaphragm (51) which extends radi- ally outwardly therefrom. The spud (13) also includes a guide (35) having a vent tube (40) slidably received thereon. The guide (35) extends axially upwardly from the body portion (14) of the spud (13) to be positioned inter- iorly of the tank (12). The lower portion of the vent tube (40) presents a skirt (45) which extends outwardly and downwardly to define a circular valve seat (49) for selec- tive, sealing engagement with the diaphragm (51). An anti- cavitation plate (75) is positioned interiorly of the skirt (45) and extends radially between the skirt (45) and the vent tube (40).
