Backflow Preventer and Why You Need One
A “backflow preventer” does exactly as its name suggests: allows the flow of water in one direction only—making it a critically important component to maintaining the safety of drinking water systems.
How a backflow preventer works
A backflow preventer responds to changes in pressure. When water flows in the proper direction, pressure pushes the valve open—allowing water to move freely. When pressure builds up in the opposite direction (backflow), pressure pushes the valve closed—eliminating risk to public health by preventing potentially contaminated water from making its way back into the supply system.
Sprinkler systems are among the places where water can become contaminated—necessitating the installation and ongoing testing of each backflow prevention device attached to such a system.
Backflow prevention testing
Plumbing cross-connections, defined as actual or potential connections between a potable (drinkable) and non-potable (non-drinkable) water supplies, are regulated by OSHA and environmental and public health agencies. Backflow prevention devices fall under this classification.
Backflow preventers normally require very little maintenance once in position and don’t need an external power supply in order to function. That said, a backflow preventer still is a mechanical device, meaning it has the potential to fail.
Each backflow device has test ports built into it to allow for testing. A backflow prevention testing technician will connect a test kit to the device and verify that it is operating properly. (Water to the device must be temporarily shut off to perform the test.)
