ABSTRACT:
A valve mechanism for draining a toilet flush tank to either one of two different drain levels selectively, chosen by a single manual bell-crank lever rockable in opposite directions connected to an adjustable link that pushes or pulls a rocking lever between two parallel ball valve tubular extensions having ball valves seated on outlets at the two different drain levels in the tank. At least one of the drain outlets may be vertically adjustable. The outlets may be formed in a manifold which connects into the single outlet of a standard toilet flush tank. The full tank level is controlled by a standard float valve at the top of an intake pipe in the tank. The refill tube from the float valve may be connected to a guide for one of the tubular extensions of a ball valve. These tubular extensions also act as overflow ducts for the tank. When the manual lever is pushed in one direction it rocks the rocking lever to urge one ball valve closed and opens the other ball valve, and when the manual lever is pulled in the opposite direction it urges the other ball valve closed and opens said one ball valve.
