Why You Need a Backflow Prevention Device Certification
This Backflow Prevention Device Certification is a legal condition of your water and sewer service in Oklahoma City. It is mandated by the city's Sewer Use Regulations (Title 39, Chapter 100 of the Oklahoma City Municipal Code) and enforced by the Water Utilities Department. These regulations exist to protect the public water supply from potential contamination due to backflow—a reversal of water flow that can pull non-potable water (from restaurant dish pits, grease traps, or boiler systems) back into the municipal drinking water system. Without this certified test on file, your utility account is considered non-compliant.
Failure to submit an annual certification from a licensed tester puts your business operations at immediate risk. The consequences of non-compliance are not merely warnings; they are enforceable actions that can halt your service. Based on analysis of enforcement actions in this jurisdiction, common penalties include:
- Service disconnection – The Water Utilities Department can shut off your water and sewer service until compliance is verified, effectively forcing a temporary closure.
- Financial penalties – You can be assessed fines for each day of non-compliance, often escalating with repeated violations, as outlined in local enforcement schedules.
- Required remediation – If backflow occurs, you may be held liable for the cost of flushing and testing the public water system, which can run into thousands of dollars.
- Permit and lease complications – Lapsed certification can trigger violations on your health department permit and may breach your commercial lease, which often requires maintaining all utility services in good standing.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: A key 2026 update: Oklahoma City now requires all commercial certification reports to be submitted digitally through the city's designated portal, as announced in the 2026 Utility Compliance Bulletin #7, replacing the previous mail-in option.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Any establishment with a permanent potable water connection and food/beverage production equipment is subject to Oklahoma City Code § 51-4, requiring an annual backflow device test and certification. |
| Bar / Nightclub | Required | Required because the presence of soda guns, ice machines, and glasswashers connected to the public water supply creates a potential cross-connection under Oklahoma City plumbing regulations (§ 51-4.2). |
| Food Truck | Required | Required if the mobile unit connects to an external city water hookup; the temporary connection point must have a testable backflow prevention assembly, per Oklahoma City Mobile Food Unit regulations. |
| Coffee Shop / Café | Required | Required due to espresso machines, steam wands, and water filtration systems that are directly plumbed, which are considered cross-connections per Oklahoma City Code § 51-4. |

19 of 23 auto-filledLegal Business Name
textEnter the exact legal name of your restaurant as registered with the Oklahoma Secretary of State, matching your Articles of Incorporation, LLC filing, or DBA certificate.
COMMON MISTAKE: Using a trading name (e.g., 'Joe's Grill') instead of the official registered entity (e.g., 'JG Holdings LLC') results in a rejection because the legal entity on file with the city must match.
Restaurant Address
textEnter the complete physical street address of the restaurant where the backflow device is installed, including suite or unit number if applicable.
COMMON MISTAKE: Submitting a mailing address, P.O. Box, or corporate office address instead of the service location's physical address causes immediate rejection, as inspections are site-specific.
Primary Contact Person
textEnter the full name of the person authorized to receive official correspondence and schedule inspections, typically the owner, general manager, or facility manager.
COMMON MISTAKE: Leaving this field blank or listing a generic title like 'Manager' without a specific name leads to communication delays and rejected applications.
Has Commercial Water Connection
checkboxCheck this box to confirm your restaurant is connected to Oklahoma City's municipal water system with a commercial-grade meter, as this triggers the backflow prevention requirement.
COMMON MISTAKE: Failing to check this box when you have a commercial connection results in an incomplete application; the city uses this to verify applicability of the ordinance.
Backflow Device Currently Installed
checkboxCheck this box only if a backflow prevention assembly is already physically installed on the premises and ready for testing; do not check it for planned installations.
COMMON MISTAKE: Checking this box before the device is installed leads to a failed initial inspection, adding 2–4 weeks to your timeline for a re-inspection.
Device Manufacturer and Model
textEnter the exact manufacturer name and model number as stamped on the device body (e.g., 'Watts 009QT', 'Febco 765Y'), which the certified tester will verify during inspection.
COMMON MISTAKE: Providing an incorrect or incomplete model number (e.g., just 'Watts') causes rejection, as the model determines the approved assembly type per city standards.
Backflow Assembly Type
textSpecify the type of backflow assembly installed, such as 'Reduced Pressure Principle Assembly (RP)', 'Double Check Valve Assembly (DCVA)', or 'Pressure Vacuum Breaker (PVB)'.
COMMON MISTAKE: Misidentifying the assembly type (e.g., calling a DCVA an RP) leads to rejection because the required test procedures and certification standards differ.
Device Installation Documentation
textList the installation details, including height above floor, clearance for testing, orientation (vertical/horizontal), and location relative to the water meter, as per the plumber's report.
COMMON MISTAKE: Omitting required clearance dimensions (e.g., '12 inches of clearance on all sides') is a common reason for a 'fail' on the initial inspection, requiring corrective work.
Certification Standard Confirmed with City
checkboxCheck this box to affirm you have verified the current testing and certification standard (e.g., AWWA C511, USC FCCCHR) with the Oklahoma City Utilities Department.
COMMON MISTAKE: Checking this box without confirming the current year's standard can lead to your tester's certification being invalid, voiding the test report.
Required Certification Standard
textEnter the specific standard code and year that your certified backflow prevention tester must follow, as listed on the Oklahoma City Utilities Department website.
COMMON MISTAKE: Using an outdated standard code (e.g., from a prior year) results in immediate rejection of the accompanying test report, invalidating the entire application.

Top 5 Backflow Prevention Device Certification Mistakes
1. Missing or Incorrect Water Account Number
Leaving the utility account number field blank or entering the account number for your business electricity or gas service instead of the water utility account. The Oklahoma City Utilities Department uses this number to pull your service file and verify the location. An incorrect account number triggers an immediate administrative rejection, adding 2–3 weeks to your timeline as you must wait for the city to identify the error and request a correction.
2. Confusing Test Date with Submission Date
Entering the date you *submitted* the application instead of the actual date the backflow prevention assembly was tested by a certified tester. The city requires the test to have been performed within the last 12 months. Using the wrong date will cause the Oklahoma City Utilities Department to deem the certification out of compliance and invalid, requiring you to pay for a brand new test. Always use the date from your tester’s official report, not the calendar day you are mailing the form.
3. Listing an Unapproved or Unlicensed Tester
Failing to verify that the person or company who performed the test is on the City of Oklahoma City’s Approved Backflow Assembly Tester list. Submitting a certification from an unapproved tester is the #1 cause of permanent rejection. The city will not accept the report, and you will have to pay a licensed tester to re-perform the entire test, incurring the full testing fee again. Always ask your tester for their official city license/approval number and verify it matches the city's current roster.

Timeline: Varies
Step 1: Determine if your restaurant requires backflow prevention certification based on Oklahoma City's local sewer use and water connection regulations
Review the <strong>Oklahoma City Municipal Code § 53-3</strong> to identify specific plumbing fixtures that trigger the requirement, typically based on your commercial water system's complexity. Most food service businesses with grease interceptors, commercial dishwashers, or multi-story kitchens are required to have certification. Check the city's online permit portal or contact the Utilities Department to confirm your specific classification. Duration: 1-2 hours.
Step 2: Identify the specific backflow prevention device(s) installed on your commercial water connection
Locate the physical device(s) on your premises — common types include RPZ, PVB, or DCV assemblies — and record the manufacturer name, model number, and size (e.g., 3/4", 1") from the identification tag. Take clear photos showing the device's serial number and installation orientation; mismatched device type reports are a top reason for application rejection. Duration: 30 minutes.
Step 3: Enroll in an approved backflow tester certification course (32-hour or 40-hour ASSE 5110 program)
Select a state-approved training provider from the <strong>Oklahoma Department of Labor's list</strong> — in-person courses typically cost $600–$800. Schedule enrollment at least 4-6 weeks in advance as classes fill quickly. You'll need to provide a valid driver's license and proof of employment/ownership at a facility requiring certification. Duration: 1-2 weeks (planning & enrollment).

See All RequirementsProcessing time varies significantly, per the Oklahoma City Utilities Department, and hinges on inspection scheduling and your contractor's readiness. It can take from a few days to several weeks. Delays often occur if your device fails its initial test or if the related Building Permit for plumbing work isn't finalized first, adding weeks to your timeline.
Government filing fees for this certification in Oklahoma City range from $32 to $5,110, according to the city's adopted fee schedule. The exact cost depends on your device's size and service type. Not legal advice — verify final costs with the Oklahoma City Utilities Department, as additional contractor fees for testing and possible plumbing modifications apply.
No, certifications are site-specific and cannot be transferred. A device at a new location requires a full application, new inspection, and certification from scratch. This process parallels other location-specific permits like a Certificate of Occupancy. Contact the Utilities Department to confirm the requirements for your new site.
Backflow device certifications in Oklahoma City must be renewed annually, as mandated by city ordinance. You must hire a licensed tester to inspect and submit the test report to the city each year to maintain compliance. Missing the renewal deadline can result in fines and water service interruption.
A licensed backflow prevention assembly tester will perform a field test to verify the device holds proper pressure and prevents any reversal of water flow. They check for proper installation, absence of leaks, and correct assembly. If the device fails, you must repair or replace it and schedule a re-inspection, which adds time and cost before certification is granted.
