What testers should know

Contact Aquarion Cross Connections before relying on a test or filing route. Aquarion rules require access for inspection and testing and allow service action when cross-connection violations or required repairs are not resolved.

Tester requirements: Confirm whether Aquarion personnel or an outside Connecticut-certified tester must perform the property-specific work.

Important: Utility instructions can change and property-specific requirements may differ. Confirm the accepted form and delivery method before relying on this guide.
