How to file your backflow test with City of Norman Utilities

1. Read your notice. It names the assembly, its location and the date the report is due.
2. Book a tester City of Norman Utilities accepts. See finding a tester below; book early so there is time to repair a failed assembly.
3. The tester tests the assembly and fills in the test report. A failed assembly is repaired and tested again.
4. The report is filed. Ask the tester how they send it to the utility, and get a copy.
5. Keep a copy and set a reminder for next year. Set a free test-due reminder.

Finding a tester City of Norman Utilities accepts

We found no tester list on City of Norman Utilities's own pages. Use a state certified tester, and check your notice in case it names the testers or the portal it accepts.

Before you book, ask the tester:

• Are you registered with City of Norman Utilities?
• Will you send the test report to the utility for me, and how?
• When is my report due? The date is on your notice; the tester needs time to test, repair if needed and file.
