The devices are installed on the City’s water supply line as close as possible to the customer’s water meter and/or internally on any equipment that utilizes water that potentially may become contaminated such as boilers, carbonators, cooling towers, x-ray machines, etc.
Who Is Required To Test and How Often?
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.
