9790Pit Drain

For use at base of side walls in pits, where low elevation requires a vertical inlet grate and side outlet roughing. Unless obstructed by debris or sludge, these backflow valves prevent backflow which could damage equipment in pit. Used for gravity flow, not for high flow pump applications. Body fabricated rough finish stainless steel with secured grade and bronze backwater valve.
