How to Prevent Standing Water With Unique New Check Valve

What is a Check Valve and Why is it Useful?

Check valves are used in all stormwater and wastewater systems. They allow the forward flow of fluids before closing to prevent backflow conditions. These valves come in a variety of diameters and designs, including ball, swing, diaphragm and duckbill check valves. They are simply designed, passive flow devices that rely on flow velocity and pressure to open and close without and manual or automated assistance. 

Properly designed and operating check valves prevent flooding and standing water, control back pressure from wastewater treatment plants and outfalls, and ensure water flows through piping in the correct direction.
