Abstract
A top mounted flush valve is installed from inside a flush tank and does not require access to the opposite tank wall. A valve body includes an annular chamber receiving a radially enlarged head portion of a flexible resilient seal member. A draw ring is fixed to the remote end of a barrel portion of the seal member. A draw collar has a flange bearing against the body and a cylindrical portion threaded to the draw ring. Rotation of the draw collar outwardly collapses the seal barrel portion, and a seal bead on the seal member head is forced against the inner tank surface. A wall of the body isolates the draw collar from the seal barrel, and the enlarged head portion is wedged into the annular chamber to prevent rotation of the seal member.
