Sand Springs, OK: what's different here
Sand Springs sits mostly in Tulsa County, about 7 miles and roughly 10 minutes from Tulsa by the main highway. That proximity puts it in the Tulsa pricing zone, where standard irrigation double check testing usually lands at the low end of the state range. The city has a local backflow and fire-protection contractor presence, so related testing help is available nearby. For city licensing and permit questions, Sand Springs posts information on its official permits page and offers an inspection line at 918-246-2572.
How often is double check valve testing required in Sand Springs?
Oklahoma's adopted plumbing code requires double check assemblies to be tested at installation, after repair or relocation, and at least once a year. Local water utilities also typically require annual testing for each installed assembly. A certified tester files the report with the utility after the test.
Who can perform double check valve testing in Sand Springs?
There is no statewide Oklahoma tester license; local water authorities approve their own testers. Many require ABPA or ASSE backflow tester certification plus the CIB plumbing license. The state publishes a tester list that includes Sand Springs-based testers with active 2026 credentials.
When should I schedule double check valve testing in Sand Springs?
Tulsa's mean first 28°F hard freeze falls on November 14, and the mean last one is March 17. That leaves roughly 241 days between hard freezes for outdoor testing and winterization work. Scheduling before the first hard freeze helps protect irrigation assemblies.
What pressure must a double check detector assembly handle?
Tulsa's water-meter specifications state that a double check detector assembly must have a minimum design working pressure of 150 psi. The same specifications require testing by a City of Tulsa-approved Back Flow Assembly Tester before acceptance. Ask the pro we refer whether your assembly meets these specs.
What to do next
- Confirm which assembly you have - a standard irrigation double check usually tests at the low end of the $50-$250 range.
- Ask the pro for proof of ABPA or ASSE backflow tester certification and the CIB plumbing license your water utility requires.
- Request that the tester file the passing report directly with your local water utility after the test.
- Book before November 14, Tulsa area's mean first 28°F hard freeze, so the test and any winterization are done in time.
