The backflow preventer is a hydraulic protection device designed to prevent polluted water from flowing back into the mains supply network. The backflow preventer is installed between the mains supply network and the internal consumer circuit in water supply systems and creates a safety zone which prevents the water in the two circuits from coming into contact.
