The purpose of the backflow preventer is to prevent back-suction or back-flow of service water into the public drinking water network. It is mainly used for filling heating devices without inhibitors and allows fixed connection of the heating filling device to the drinking water system. The practical design allows a quick check of the system disconnector status. At a glance, you can see if the disconnector is open or closed. When no water is drawn, the one-way valves at the inlet and outlet are closed. The pressure on the inlet side decreases when it is sucked back in. The drain valve opens at the latest when the differential pressure between the front and middle pressure chambers drops to 0,14 bar.
