Connecticut requirements library
Backflow testing rules depend on the water utility—not just the town.
Use this library to identify the likely program, testing cadence, and official contact for a Connecticut property. Every published page includes a verification date and links back to utility or state sources.
Towns can have more than one water provider. We show every verified utility that may serve the selected town.

Connecticut DPH cross-connection guidance
Connecticut’s Department of Public Health sets the statewide cross-connection framework. Water utilities administer property-level inspections, testing, forms, and reporting, so always confirm the current local route.
For testing companies
Turn every due date into a booked re-test.
Import your customer book, track assemblies, capture field tests, and keep district instructions attached to the property.
