Backflow devices are crucial for protecting your drinking water. Backflow prevention involves the implementation of valves and other mechanisms that can be installed on a water supply line. These backflow devices work by effectively preventing contaminants from flowing back from your home or business into the main drinking water source.

By utilizing check valves, air chambers, and vacuum breakers, these devices ensure that pressure does not build up in the pipe, which could lead to the escape of contaminants into the main water supply.

Schedule your annual backflow device test

It is important to note that regular maintenance is required for backflow devices. Be sure to schedule your annual backflow device test to guarantee that these devices are functioning effectively. By doing so, you can ensure the continued protection of your drinking water supply.

The Washington State Department of Health, Office of Drinking Water, has authorized Washington Certification Services at Green River College to maintain a list of certified Backflow Assembly Testers (BAT) that may provide testing services.
