Backflow Prevention

Backflow Prevention

Cleveland Water works hard to ensure that the drinking water delivered to your home or business is safe at all times. One way we do this is by regulating backflow, or potential cross connections between drinking water pipes and sources of contamination.


Backflow occurs when water pressure drops and water is pulled into your plumbing from an unprotected cross connection in your home or business. Common examples of cross connections include lawn irrigation, fire sprinkler systems, and garden hoses submerged in water.

Backflow-prevention devices stop these contaminants from entering the water system. A licensed plumber must test these devices every year. Customers are notified via mail when their device requires testing.

Plumbers are required to submit the results of these tests to Cleveland Water. Cleveland Water contracts with Backflow Solutions Inc. (BSI) to track all of the backflow testing data from our customers to ensure that owners have a working backflow device on their property. Plumbers must submit their test results through BSI's website.
