<p>A flush valve (18a) is adapted to be mounted in the tank (14) of a toilet (10) and includes a selector assembly (36a) and a flush valve (30). The selector assembly (36a) is accessible from outside the toilet (10) and provides for initiation of the flushing operation and an alternative choice between a larger flush water volume and a smaller flush water volume. A support structure (92a) provides for both axial and radial movement of the selector assembly (36a) relative to the flush valve (30) in order to facilitate mounting and aligning of the flush valve assembly (30). A slide mechanism (123a) provides for variation of at least the smaller flush water volume.</p> |
