Round Compression Seal Type Backwater Valve

Figure Number:  701
Designed for installation in new or existing drains where protection from sewer backflow is required. When the sewer begins to back-up, the float in the backwater valve rises to seal the drain opening until the water recedes. This valve protects basements and low lying areas in homes and businesses against sewer back-up.
