A vertical rod channel is defined in the bracket at an adjustable lateral distance from the stand pipe. A valve rod slides up and down in the rod channel and is connected to the flush lever. A valve member mounted to the bottom end of the valve rod is configured to engage the valve seat to seal the top end of the flush water outlet. The valve member is configured such that same sinks in water. A float is attached to the valve rod at one of a plurality of vertical float locations and the float is operative, when immersed in water, to prevent the valve member from sinking.
