Abstract:
A backwater valve has a hollow valve body with an inlet defined by a vertical surface, an outlet, and a bottom. A pivoting valve member is pivotally movable about a pivot axis between a normally open position along the bottom of the valve body and a closed, vertical position sealing the inlet. The valve member has a hinge end, the pivot axis being positioned at the hinge end. An overbalancing member carried by the valve member biases the float toward the closed position. The overbalancing member comprises at least one of a counterweight and a magnetic element. The overbalancing member is positioned at the hinge end and spaced from the pivot axis such that the overbalancing member is vertically above the pivot axis when the valve member is in the open position and horizontally over from the pivot axis when the valve member is in the closed position.

Claim (Index 2):
The backwater valve of  claim 1 , wherein one of the first magnetic element and the second magnetic element is magnetized and the other of the first magnetic element and the second magnetic element is ferrous.
