Abstract:
A method of controlling water level in a lush tank of a toilet comprising the steps of:controlling the supply of water to the flush tank with a main valve mounted atop a riser; controlling the opening and closing of the main valve with a pilot valve; controlling the water level in the flush tank by attaching a container with a buoyant element disposed therein to the riser at a selectable, fixed position: and adjustably connecting the buoyant element to an arm portion of the pilot valve relative to an interior of the container so that when the water rises to a selected level in the flush tank, the container is suddenly filled with water when the water reaches a top edge of the container, causing the buoyant element to abruptly rise in the container and shut the pilot valve so that the main valve is closed.
