Find a Certified Tester Near You
Milwaukee property owners with irrigation systems, commercial connections, or fire suppression lines are required to maintain annual backflow assembly testing under Wisconsin's cross-connection control rule (Wis. Admin. Code NR 811.44), enforced locally by Milwaukee Water Works. As Wisconsin's largest city, with a dense mix of historic neighborhoods, industrial corridors, and a growing downtown core, Milwaukee runs one of the state's most active backflow compliance programs.
Cross-Connection Risk in a Historic Industrial City
Milwaukee’s older neighborhoods near the Menomonee Valley and its many converted industrial buildings often have legacy plumbing connections that the city flags for closer monitoring. A certified tester will inspect your assembly, confirm it meets current performance standards, and submit results directly to Milwaukee Water Works to keep your account in good standing.
