Finding a tester Columbus City Utilities accepts

We found no tester list on Columbus City 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 Columbus City Utilities?
• Will you file the report in Aqua Backflow for me, and pay or pass on any filing fee?
• When is my report due? The date is on your notice; the tester needs time to test, repair if needed and file.
