Stainless Steel Check Valves are used in water wells to keep the water from draining back down to the water level when the pump is not pumping. Most pumps have a built in check valve that is in the top of the pump. Manufacturers tell you not to use that flat washer check as your only check valve in the well. The recommendation is to place a check valve at the first joint of pipe above the pump, and one every 6 to 7 joints on up in the well. This prevents the water from draining down and causing an upthrust condition where the pump does not have enough water weight above it to protect against upthrust, that can damage pump motor bearings and impellers and diffusers in the pump. Stainless Steel Check Valves meet the new requirements in California and many other states requiring the use of materials other than brass in water well pumping potable water.
