Backflow is generated by cross-connections that have the possibility of permitting pollutants into the drinking water system. Back siphonage can happen when the pressure in a tank is less than the water system's pressure.
Check valves offer a basic form of backflow prevention, stopping water from flowing in the wrong direction.
Double-check valves (also known as double-check assembly) are somewhere in between a check valve and a backflow preventer. They are usually installed in places where backflow requires to be contained with a one-way valve, but the investment needs to be less than a backflow preventer.
