Plumbing Code and state regulations require that backflow preventers be tested annually and/or when a backflow preventer is 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 that 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. If an outside device on an irrigation system is not installed for the year there is a waiver form from Aqua Backflow to fill out that will satisfy the testing requirements for the year.
With the current pandemic, the Illinois Plumbing Code has not been adapted or changed and device owners are still responsible for the annual testing requirements. If you are unable to meet the testing deadline, you can contact Aqua Backflow at the number below and let them know when a testing date is scheduled. This effort will keep the account from going out of compliance and keep any additional fees from being applied. The Village’s goal is to have 100 percent compliance with these requirements to help ensure that safe drinking water is delivered to our customers.
The Village asks for your cooperation with our program, its enforcement, and any requests for information that come from Aqua Backflow or Public Works staff. Aqua Backflow is the contractor hired to administer and oversee the Village’s CCC program and can be reached at (847)742-2296 or via their website with any questions. Aqua Backflow does not test, install or repair backflow devices.
