Backflow prevention assemblies are to be tested annually or more often if requested by the Environmental Division. The Cross Connection Program applies to and is primarily enforced on commercial businesses. However, circumstances may apply that would require these devices to be installed on non-commercial properties. It is recommended that when installed on residential properties that these devices be tested annually by a Certified Tester to ensure equipment performance.
How Can Backflow Be Prevented?
Installing approved backflow prevention assemblies, such as Reduced Pressure Principle Assemblies, Double Check Valves, Pressure Vacuum Breakers, and the use of Air Gaps, can significantly reduce the chances of a backflow situation from occurring.
