Why does the utility want a backflow device tested?
A backflow notice is usually sent because your property has a backflow prevention device. The utility wants it tested on a recurring schedule to protect the public water supply from contamination. Local water purveyors in Oklahoma set the testing schedule for homes.
How often is a backflow test required?
Testing is commonly required at installation, after repair or relocation, and once a year. Oklahoma's adopted commercial plumbing code requires annual inspections of backflow assemblies under IPC 312.11.1, effective September 14, 2026.
Why do sprinkler systems often need backflow testing in Tulsa?
Tulsa has a growing season of 216 days, so outdoor irrigation runs for many months. That long season often increases backflow-device use on sprinkler systems. Freezes can also stress these assemblies, since Tulsa's average first 32-degree day is in early November.
What happens if I ignore the notice?
Ignoring a backflow test notice can lead to non-compliance letters and fines under local ordinance. Continued non-compliance can eventually lead to shutoff of water service.
What to do next
- Read your notice and note the device location, the due date, and the water utility that issued it.
- Verify the tester holds ABPA or ASSE certification, since most Oklahoma jurisdictions require it.
- Confirm the tester is approved by your city or rural water district, because there is no statewide Oklahoma tester license.
- Ask the quote to include the test, the filed report to your water utility, and the price, which is typically $50 to $100.
- Call (918) 202-2068 or email [email protected] for a free quote from a licensed, insured local backflow testers.
