New London Public Utilities backflow testing requirements
New London publishes a municipal-water application that requires a testable reduced-pressure backflow preventer when a live well remains on a property and places that property under cross-connection control.
What testers should know
Contact New London Public Utilities before work to confirm whether the property requires protection, the accepted device and tester, inspection scheduling, test frequency, and reporting route.
Tester requirements: Use a Connecticut-certified tester when testing is required and coordinate inspection with New London Water and Sewer.
Important: Utility instructions can change and property-specific requirements may differ. Confirm the accepted form and delivery method before relying on this guide.
