Owasso, OK: what's different here
Owasso sits in Tulsa County, about 14 miles and roughly 19 minutes from Tulsa via US-169. Its housing stock is heavily detached single-family, making up 74% of units, and the city needs 1,999 new housing units over the next five years to keep up with growth. The climate is humid subtropical, with an average annual temperature of 60°F and 39.5 inches of precipitation. The Owasso Public Works Authority has also received $1,041,000 in OWRB funding for wastewater infrastructure improvements.
Who can test backflow devices in Owasso?
City of Tulsa specifications require backflow assemblies to be tested by a City of Tulsa-approved Back Flow Assembly Tester before acceptance. Qualified testers hold a backflow prevention license meeting International Plumbing Code criteria and training from a recognized licensing entity. Ask any pro for proof before they start.
How often should sewer backflow prevention be checked?
City of Tulsa guidance says a lawn irrigation system backflow preventer should be tested annually by a qualified professional. The same rule is repeated across Tulsa's backflow program materials. Annual testing is the standard to plan for.
How does Owasso's climate affect backflow devices?
Owasso sees average summer highs of 94°F and about 14 inches of annual snowfall, which stresses outdoor plumbing and backflow devices. Tulsa-area climatology shows a mean first 28°F hard freeze on November 14 and a mean last one on March 17. Seasonal winterization timing matters for outdoor assemblies.
What pressure standards apply to backflow assemblies?
The City of Tulsa water-meter specifications state that a double check detector assembly must have a design working pressure of at least 150 psi. Assemblies must also pass testing by an approved tester before acceptance. Ask your pro to confirm your device meets these specs.
