Abstract
A rotatable toilet tank lever equipped with a stopper has a controller to limit its upward movement. When engaged, the upward movement of the controller is stopped by an adjustment stick hitting the cover of toilet water tank. Therefore, the upward movement of the flapper inside the toilet tank is also limited and the amount of water, about half a gallon, draining into the toilet suffices to flush liquid human waste. When the intervention of the controller is eliminated by turning the handle of the rotatable toilet tank lever with controller clockwise 90 degrees to 180 degrees then the flapper can be lifted all the way up to float in the toilet water tank to allow the whole tank of water, about two gallons, to drain into the toilet bowl to flush solid human waste.
