A lever is connected to the float such that the lever moves in response to movement of the float. An extension member is connected to the lever and positionable to be manually reached by an operator standing at ground-level to permit the operator to selectively move the lever by actuating the extension member when the lever is positioned at a height that causes the lever to be out of manual reach of the operator while the operator is standing at ground-level.
