Just like any other mechanical device, backflow prevention assemblies are prone to wear and tear, and do break down from time to time. Regular testing is required in order to ensure that your device remains in proper working order.

(Varies by state and local authority)
It is recommended that all testable backflow preventers are tested annually, however The City/Village/Township may require less frequent testing on residential lawn irrigation systems. (Consult your local Cross-Connection Control ordinance.) If you are injecting chemicals into your lawn irrigation system, most state regulations and plumbing codes require the backflow preventer to be tested on an annual basis.

In most jurisdictions, a lawn irrigation system is not a required component of the water system. Facility owners who choose to install a lawn irrigation system as a convenience are responsible to assure the backflow preventer is properly installed and maintained in accordance with State laws and regulations. It would be unfair for the City/Village/Township to require facility owners who choose not to have a lawn irrigation system to absorb the financial burden of maintaining your privately owned system.

There are two parts to the Cross-connection Control Program. The first is an on site inspection by a cross-connection control inspector to ensure that the proper backflow prevention devices and assemblies are in place to protect your drinking water. Some of the assemblies the inspector finds or asks you to install are testable assemblies, which are mechanical and can malfunction. The testing notice refers to testing the operation of these backflow prevention assemblies. These tests must be performed by a certified tester.

“Grandfathering” is not typically permitted due to the high importance of maintaining drinking water safety. Just like any other mechanical device, backflow prevention assemblies are prone to wear and tear, and do break down from time to time. Regular testing is required in order to ensure that your device remains in proper working order.

These require periodic performance testing by a  Certified Tester.
