Owasso, OK: what's different here
Owasso sits about 14 miles from Tulsa, roughly a 19-minute drive via US-169. Because Oklahoma has no statewide tester license, the certificate accepted in Owasso must be verified with the local water authority. Many purveyors in the area follow the same ASSE/ABPA approach Tulsa uses under Title 14. That makes annual testing and reporting the key compliance deadline for Owasso property owners.
What certification does a tester need for city compliance backflow certification in Owasso?
Oklahoma has no statewide backflow tester license; each city or rural water district approves its own testers. Most Oklahoma water purveyors require ABPA or ASSE backflow tester certification, often alongside the CIB plumbing license that covers the work. Tulsa references ASSE/ABPA certification under Title 14 §901.6.3, which shows the credential type commonly accepted near Owasso.
How long does backflow tester certification take in Oklahoma?
Certification training is commonly offered as a 32-hour class priced at $750. ASSE 5110 tester classes run 40 hours and cost $800, with the exam given on the final day of training. One Oklahoma business guide says the process typically takes 2 to 3 days for the approved course, followed by a state exam, with certification and startup licensing costs of about $400 to $700 total.
How often must backflow assemblies be tested in Owasso?
Most water authorities in Oklahoma require annual testing and reporting for backflow prevention assemblies. Tulsa guidance also says a lawn irrigation system backflow preventer should be tested annually by a qualified professional. Confirm the exact reporting deadline with the local water authority serving your Owasso property.
When is the best season to schedule a backflow test near Owasso?
National Weather Service climatology for the Tulsa area shows a mean first 28°F hard freeze on November 14 and a mean last hard freeze on March 17. That gives roughly 241 days between hard freezes, so spring and early fall are comfortable windows for annual testing. Schedule before mid-November if winterization is also needed.
What to do next
- Ask the tester whether your assembly is a standard irrigation double-check or an RPZ or fire-line device, since pricing sits at $50 to $250 per device.
- Verify with your Owasso water authority which certificate it accepts, such as ABPA or ASSE, since each city or district approves its own testers.
- Ask for proof of the tester's certification and insurance before the test is performed.
- Schedule the annual test and report well before the November 14 mean first hard freeze if winterization is involved.
