Lawn Irrigation System Spring Start-Up: Backflow Devices Must Be Tested

irrigation-system-sprinklercropped

Plumbing Code and state regulations require that backflow preventers be tested annually and/or when a backflow preventeris relocated or re-installed every season. The water customer must contract with a licensed tester to perform the required annual tests and any necessary repairs. Most plumbing contractors are certified to test backflow preventers. Note there are costs associated with testing and maintaining backflow devices.

Federal, state and local regulations require every municipal water supplier to develop, implement, and maintain a comprehensive Cross Connection Control (CCC) program designed to safeguard the public water supply. Cross connections are sometimes protected by a valve called a backflow preventer. Backflow preventers are the property of the water customer and the responsibility lies with the customer for required annual testing and maintenance.

Residential backflow preventers may be found on lawn irrigation systems, wet fire protection systems, hot water heating (boiler) systems, swimming pool fills, water features, etc. Backflow preventers may also be found or required if there is another water source on the site such as a well, pond, river, etc.

The Village asks for your cooperation with our program, its enforcement, and any requests for information that come from Aqua Backflow or Utility staff. Aqua Backflow is the contractor hired to administer and oversee the Village's CCC program and can be reached at (847)742-2296 with any questions. Aqua Backflow does not test, install or repair backflow devices.
