The Purpose of Backflow Prevention Devices
Backflow prevention devices are generally installed anywhere in a piping network that involves substantial cross-connections. They prevent non-potable water from contaminating municipal drinking water.
How Do Backflow Preventers Function?
Backflow preventers contain check valves that respond to pressure when there is up flow and reverse travel. When there is pressure, an empty space between the two check valves and a diaphragm activates. As pressure increases, the gate opens to permit the chamber to fill. Once this area is full, the second gate opens; both gates close when the inlet is shut off. As a result, there is no backflow.
