Jenks, OK: what's different here

Jenks sits in Tulsa County, about 11 miles and roughly 15 minutes from Tulsa by main highway. It is a fast-growing suburban market - one housing analysis puts the median price of a new single-family home in a Jenks subdivision at $369,000. The city has 28,815 residents and needs 1,135 more housing units over the next five years. That growth keeps adding irrigation systems and backflow devices that need yearly testing.

Is annual backflow testing required in Jenks?

Yes. The adopted Oklahoma Plumbing Code requires testing at installation, after repair or relocation, and at least once a year. Most Oklahoma water authorities also require annual testing and reporting for all backflow prevention assemblies.

Who can perform backflow certification in Jenks?

There is no statewide backflow tester license in Oklahoma; each city or rural water district approves its own testers. Most purveyors require ABPA or ASSE backflow tester certification, often with a CIB plumbing license for the work. Ask the pro for proof of licence and insurance.

What affects the cost of annual backflow certification?

Assembly type and local filing fees drive the price. In the Tulsa area, a standard irrigation double-check test is often near the low end of the $50 to $250 range. RPZ assemblies and commercial fire lines cost more.

When should irrigation backflow devices be tested in Jenks?

Tulsa's climate matters for timing: the mean first 28°F hard freeze is November 14 and the mean last is March 17, about 241 days between hard freezes. Test your irrigation backflow preventer before the fall freeze window and after spring startup.

What to do next
