Bixby, OK: what's different here
Bixby sits in Tulsa County, about 18 miles and roughly 29 minutes by car from Tulsa via the main highway. The city lies in a transition zone between IECC climate zones 3A and 4A, so freezing risk matters for outdoor and buried backflow assemblies. Local soil is expansive Permian Red Bed clay mixed with loess, which swells when wet and shrinks when dry. Because Bixby is in Tulsa County, county jurisdiction applies to related local permitting and environmental rules.
How often is backflow device recertification needed in Bixby?
Most Oklahoma water authorities require annual testing and reporting for backflow prevention assemblies, so recertification is typically needed every 12 months. Tulsa city guidance also says lawn irrigation backflow preventers should be tested annually by a qualified professional.
Who can perform backflow device recertification in Bixby?
Oklahoma has no statewide tester license. Each city or rural water district approves its own testers, and many require ABPA or ASSE certification along with the CIB plumbing license that covers the work. Local water authorities may keep approved-tester lists.
How does Bixby weather affect backflow assemblies?
Bixby sits in a transition zone between IECC climate zones 3A and 4A, so freezing risk affects outdoor and buried backflow assemblies. The Tulsa area averages a first 28°F hard freeze around November 14 and a last one around March 17, which matters for winterization timing.
How do testers get certified in Oklahoma?
A common training path is the ASSE 5110 backflow tester class, which runs 40 hours and includes a 100-question written exam. The class requires 5 years of plumbing or related experience and costs $800 for the class and certification test.
