The backflow preventer is a hydraulic protection device designed to prevent polluted water from flowing back into the mains system. This type of backflow may occur when the pressure in the distribution system changes and causes a reversal of the flow. The backflow preventer is installed between the main water system and the internal user circuit in domestic water distribution systems and creates a separation zone that prevents the water in the two circuits from coming into contact.
