ABSTRACT:
A toilet room flush valve body is connected to a control stop body by means of a tail having a tapered outer surface. The larger end of the tail is connected to the control stop body and the smaller end of the tail is connectd to the flush valve body. The connection between the flush valve body and the tail is fixed, with the connection between the control stop body and the tail being adjustable. The connection between the control stop body and the tail includes a coupling nut threadedly connected to the stop body and having a flange which is inwardly directed toward the tail tapered outer surface. The stop body outlet has an end surface thereon which, with said control nut flange, define a chamber extending peripherally about the tail. A locking ring is positioned within the chamber and clamped by the flange against the end surface and the tail tapered outer surface to adjustably attach the tail to the stop body in a manner to prevent water pressure within the valve body from moving the valve body away from the stop body.
