All Elastomeric Inline Duckbill Check Valves for Prevention of Sewage Backflow in Lift Stations and Wastewater Treatment Plants

Red Valve Company

It can be costly for municipalities when lift station check valves fail and leak sewage back into the wet well from force mains, although it is an everyday occurrence. Pump wear—as well as the operational expense of inspecting, cleaning, repairing and maintaining check valves—is well documented. Also understood is the expense of force main sewage backflow into the wet well having to be pumped multiple times. This paper is a brief discussion of the techniques and use of inline duckbill all-elastomeric check valves to prevent force main sewage backflow.
