Owasso, OK: what's different here
Owasso is in Tulsa County, about 14 miles north of Tulsa via US-169 North, roughly a 19-minute drive. Many homes were built in the early 2000s, giving the city a median housing age of about 21 years. The climate is humid subtropical with an average annual temperature of 60°F and about 39.5 inches of precipitation. Spring and summer storms are frequent along the Highway 169 corridor.
Who can perform rpz valve testing in Owasso?
Oklahoma has no statewide backflow tester license, so each city or water provider approves its own testers. The City of Tulsa requires testing by a City-approved Back Flow Assembly Tester before acceptance. Ask any pro for proof they are on your water provider's approved list.
Why does rpz valve testing cost more than other tests?
Typical backflow testing in Oklahoma runs about $50 to $250 per device. RPZ assemblies usually sit toward the higher end of that range because the assembly has more components to check. Get the exact price in a written quote before the visit.
How does Owasso weather affect backflow assemblies?
Owasso sits in Tornado Alley along the Highway 169 corridor, in the same metro storm path as Tulsa. The Tulsa area averages a first 28°F hard freeze around November 14 and a last one around March 17. That freeze window matters for winterizing irrigation backflow preventers.
What training does a backflow tester need?
A backflow tester certification course can run 40 hours and includes an initial certification exam. The ASSE 5110 training lists a prerequisite of 5 years of experience in plumbing or a related industry. Ask the pro which certification they hold.
What to do next

- Ask each pro for proof of their backflow tester certification and insurance before booking.
- Request a written quote showing the per-device price, since RPZ assemblies usually cost more than other assemblies.
