What should I do first this week?

Confirm with the City of Tulsa or your water provider whether they require an approved tester and annual test filing. Ask for their accepted-tester list before you hire anyone. Then check which assembly you have, such as an RPZ, PVB, or DCVA, so you can tell the tester what to expect.

What should I check when hiring a tester?

Ask for proof of current ASSE 5110 tester certification and a valid CIB plumbing license. Ask for proof of licence and insurance and confirm the tester has experience with your device type. Make sure the quote covers the inspection, the required pressure tests, and filing results with the water authority.

How do I coordinate with the office?

Tell the front desk or security team that a contractor is coming, and give them the visit window. Ask the pro whether the visit can be scheduled during your business hours. Many Tulsa providers advertise same-day availability when you need a fast appointment.

What compliance standards apply?

Tulsa commercial testing follows Oklahoma DEQ cross-connection rules and City of Tulsa requirements. Oklahoma has no statewide tester license, so each city approves its own testers. Repairs should be done by an ASSE 5130 certified repairer.

What to do next

Call your water provider or the City of Tulsa and ask for its approved backflow tester list and annual filing deadline.
Identify your assembly type on the parking-lot irrigation line (RPZ, PVB, or DCVA) and note its location.
Ask each pro for a current ASSE 5110 tester certificate and CIB plumbing license before booking.
Request a written quote that includes the test, pressure readings, and filing with the water authority.

Quick answers

Do you test multiple assembly devices on one site?

Yes, many commercial sites have several assemblies, and the pros we refer can test each one. Ask the pro to quote each device separately so you can compare the total.

Can you schedule during specific business hours?

Ask the pro to book a window that fits your office hours, such as before opening or after close. Many Tulsa providers advertise same-day availability when you need it fast.

Do you handle the submission to the city?

Many Tulsa commercial testers file compliance results with the local water authority as part of the visit. Confirm this in writing before you book.

What is the price per device for commercial lots?

Commercial tests commonly run $180–$300 per device in the Tulsa area. RPZ and commercial assemblies tend toward the higher end of the range.
