Does Oklahoma license backflow testers statewide?
No. Oklahoma has no statewide backflow tester license. Cities or rural water districts approve their own testers, so the approval that applies depends on your local water provider.
What credentials should a Tulsa backflow tester have?
Most Oklahoma water purveyors require ABPA or ASSE backflow tester certification. The work is also typically covered by a CIB plumbing license. Check both before you hire anyone.
When should backflow testing be scheduled?
Tulsa's average first 32°F freeze is November 3, and the average first 28°F hard freeze is November 14. Schedule testing and winter protection before these dates to avoid freeze damage.
What to do next
- Ask the tester for a current ABPA or ASSE certification and verify it with the issuing body.
- Confirm the CIB plumbing license covering the work using the state licensing list.
- Ask your water provider (city or rural water district) which testers they approve.
- Request a written quote that lists the RPZ test cost, the $15 filing fee, and the test date before November 3.
