The prime usage of these valves is to ensure the flow of water in one direction and to completely stop the return flow. These are widely applicable in commercial as well as domestic establishments owing to their quality. A reflux valve is designed to prevent the water and sewerage from flowing back into the private property drain when the sewer main or on-site treatment plant becomes inundated during a flood event.

A reflux valve is used in the suction line of the pumping system to prevent the backflow when the pump is at the rest. It is a one-way valve, opening upward. A reflux valve is commonly known as a check valve and nonreturn valve water tends to flow from higher pressure to lower pressure. Mains pressure is kept higher to suffice water distribution in a house. Sometimes mains pressure is reduced due to the need for water in fire fighting.
