7070Terminal Backwater Valve

These Terminal Backwater Valves are designed for placement on the end of sewer lines which discharge in manholes, catch basins, drainage lagoons and seawalls. They are engineered to protect areas from reintroduction of wastewater that has already been evacuated. They are fabricated of corrosion resistant Duco coated cast iron and are fitted with bronze or delrin flappers for long, maintenance free, service.
