For customers with backflow prevention devices, this means you will now receive notifications, on District letterhead, when your device(s) are due for inspection. Each notice will include instructions on how to submit test results to HydroCorp, along with payment directions for the service, which is due at the time each test is submitted. Test results may be submitted either by the customer or by the certified tester.

HydroCorp will handle all questions related to backflow notices, testing, and submittals. If you need assistance, please call 844-493-7641 Monday through Friday 8 AM to 8 PM ET or email contactus@hydrocorpinc.com.
