Abstract

See full text

A backwater valve has a hollow valve body having an inlet and an outlet, and a valve member pivotally movable about a pivot axis disposed above the inlet. The valve member pivots between an open position in which the valve member is away from the inlet and a closed position in which the valve member closes the inlet. A cam is rotatably mounted above the inlet. The cam has a first rotary position in which the valve member is permitted to move to the open position and a second rotary position in which the cam engages the valve member to secure the valve member in the closed position. With the valve member in the open position, the cam pushes the valve member toward the close position as the cam moves toward the second rotary position.
