How long does a commercial backflow test take in Tulsa?
A backflow test job generally takes about 20 to 30 minutes per assembly. Larger commercial sites can take longer because of device access and multiple assemblies on the property.
Who can test backflow devices in Tulsa, OK?
There is no statewide tester license in Oklahoma; each city or rural water district approves its own testers. Tulsa requires testing by a City of Tulsa-approved Back Flow Assembly Tester before acceptance. Most Oklahoma purveyors require ABPA or ASSE certification, and the work ties to the plumbing license covering the installation or service.
What happens if a backflow assembly fails the test in Tulsa?
If a device fails testing, repairs or rebuilds are billed separately from the test. The assembly must usually be retested before it is approved.
When should commercial backflow devices be checked before freezing weather?
Tulsa's average first fall freeze is November 3, and the average first hard freeze is November 14. Freezing weather can damage backflow assemblies and outdoor plumbing, so test and winterize before those dates. The area averages about 241 days between hard freezes.
What to do next
- Ask for an itemized quote listing the device count, assembly types (RPZ, fire line), and the $75-$150 basic test price.
- Verify the tester is City of Tulsa-approved and holds ABPA or ASSE certification, plus the plumbing license covering the service.
- Schedule testing before November 3, Tulsa's average first freeze, to avoid freeze damage to outdoor assemblies.
