Why You Need a Backflow Prevention Device Certification
Dallas property owners are required by Dallas City Code, Chapter 49 "Water and Sewers," Article V "Cross-Connection Control" to install, test, and maintain approved backflow prevention devices on any service connection where there is a potential for contamination of the public water supply. The Dallas Water Utilities (DWU) administers this program. The requirement applies specifically to facilities that pose a hazard to the public water system, which typically includes restaurants due to the presence of commercial dishwashers, grease interceptors, and other equipment that can create cross-connection risks.
Failing to maintain a valid, annual certification has significant consequences. Based on ApronPrep's analysis of enforcement actions in Dallas, common penalties include:
- Service Disconnection: Dallas Water Utilities can physically shut off water service to the property until the device is tested and certified, halting all operations.
- Fines and Fees: Property owners face administrative fines for non-compliance, plus all costs associated with required remediation and re-inspection.
- Permit and Lease Jeopardy: An active water violation can trigger a review and potential revocation of your Certificate of Occupancy or health permit. It also commonly violates commercial lease covenants, putting your tenancy at risk.
- Insurance Implications: A water contamination event traced to an uncertified device can lead to denied liability claims and policy cancellations.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of early 2026, Dallas Water Utilities has fully transitioned to its online portal for all backflow test report submissions, phasing out paper forms and requiring certified testers to use the digital system.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required for all facilities with a direct connection to the city potable water system and an on-premises water heater, per Dallas Water Utilities (DWU) Cross‑Connection Control Program Manual § 4.1. |
| Bar / Nightclub | Required | Required due to high-risk fixtures like glass‑fillers, dipper wells, and soda systems that can create a cross‑connection, as defined in Dallas City Code Chapter 49. |
| Food Truck | Not Required | Typically exempt, as potable water is supplied via an approved potable water tank and hose‑bib vacuum breaker; the certification requirement applies to fixed connections to the city water main. |
| Coffee Shop / Café | Required | Required if equipment like espresso machines, combi‑ovens, or commercial dishwashers are directly plumbed, creating a potential cross‑connection (DWU Program Manual § 4.3). |

27 of 32 auto-filledLegal Business Name
textEnter the exact legal name of the business entity that owns the restaurant, exactly as it appears on your formation documents filed with the Texas Secretary of State or county clerk.
COMMON MISTAKE: Using the DBA (Doing Business As) name, the restaurant's concept name, or an abbreviated version instead of the registered legal entity name.
Property Address
textEnter the full street address of the restaurant property where the backflow device is installed, including the building number, street, and suite or unit number if applicable.
COMMON MISTAKE: Entering a mailing address, a P.O. Box, or the address of a corporate office that differs from the physical service location.
Dallas Water Utilities Account Number
textEnter the 10-digit account number assigned to this specific property by Dallas Water Utilities (DWU), found on your water bill or service initiation paperwork.
COMMON MISTAKE: Entering a meter number, a previous account number from a different location, or an incorrect number of digits, which delays verification with DWU records.
Backflow Device Installed
checkboxCheck this box to certify that a backflow prevention assembly has been physically installed on the potable water line serving your restaurant, per Dallas City Code Chapter 49.
COMMON MISTAKE: Checking the box before the device is actually installed and tested by a licensed tester, which constitutes a false certification.
Installation Requirement Acknowledged
checkboxCheck this box to acknowledge that installation of an approved backflow prevention device is required for your type of food service business to protect the public water supply.
COMMON MISTAKE: Skipping this box, which the Dallas Water Utilities Department interprets as a failure to acknowledge a mandatory legal requirement.
Device Manufacturer
textEnter the brand name of the installed backflow prevention assembly (e.g., Watts, Febco, Wilkins) as stamped on the device's nameplate.
COMMON MISTAKE: Entering the installer's company name, an incorrect brand, or using abbreviations not recognized on the approved assemblies list.
Device Model Number
textEnter the specific model number or series (e.g., 009QT, 7FA) as stamped on the device's nameplate to verify it is an approved model.
COMMON MISTAKE: Entering a serial number, an incorrect model that is not on Dallas's approved list (Foundation for Cross-Connection Control and Hydraulic Research), or leaving it blank.
Device Installation Date
textEnter the date (MM/DD/YYYY) the backflow prevention device was installed and initially tested, which must be within the last year for a new certification.
COMMON MISTAKE: Entering the date of the test report instead of the physical installation date, or using an incorrect format, causing a mismatch with tester records.
Device Location Description
textDescribe the precise location of the device for inspectors (e.g., 'In mechanical room, south wall, next to water heater' or 'In exterior vault near dumpster pad').
COMMON MISTAKE: Using vague descriptions like 'in back' or 'by kitchen,' which fail the city's requirement for unambiguous access instructions for annual inspections.
Device Area Clear and Accessible
checkboxCheck this box to certify that the device is not obstructed by storage, equipment, or walls and is readily accessible for testing and repair per Dallas regulations.
COMMON MISTAKE: Checking the box if the device is behind locked doors without a provided key, buried in storage, or otherwise inaccessible, leading to a failed inspection.

Top 5 Backflow Prevention Device Certification Mistakes
1. Incorrect Device Type & Model Number
Entering a generic device name (like "backflow preventer") or omitting the specific model number causes immediate rejection by Dallas Water Utilities. The city requires the exact model listed on the device's tag, such as "Watts 009QT" or "Febco 825Y." Misidentifying this adds 2-3 weeks to your timeline as you must resubmit with a corrected inspection report.
2. Missing or Invalid Tester Information
Dallas requires the tester's state-issued license number, expiration date, and a valid Texas Commission on Environmental Quality (TCEQ) Backflow Prevention Assembly Tester (BPAT) license. Using a tester whose license has lapsed or submitting a form without the license number results in a non-processing notice. Always verify your tester's current TCEQ status before the inspection.
3. Wrong Service Address or Parcel ID
Submitting the restaurant's mailing address or a nearby cross-street instead of the precise physical address and city-assigned Parcel ID (also known as a Tax Account Number) triggers a rejection. The city cross-references this with utility accounts. An incorrect Parcel ID, like using an adjacent lot's number, can delay approval by 10-15 business days while they resolve the discrepancy.

- Dallas may charge application/compliance verification fees
Timeline: Varies
Step 1: Hire a licensed Backflow Prevention Assembly Tester (BPAT) certified by Texas Commission on Environmental Quality (TCEQ)
Contract with a TCEQ-licensed BPAT (license # required) before your water service is activated. Verify their license is active on the TCEQ website. Hiring a tester not on the official registry is the most common reason for rejected certifications, which can delay your Certificate of Occupancy.
Step 2: Schedule backflow prevention device inspection with your BPAT on your commercial water connection
Coordinate with your plumber and BPAT to ensure all devices are installed, accessible, and not buried. Schedule the test after final plumbing inspection but before your final health department inspection. Missing this window adds 1-2 weeks to your opening timeline.
Step 3: BPAT conducts inspection and testing of your backflow prevention assembly per state regulations
The BPAT will perform a physical inspection and a pressure test on each assembly (typically RPZ, DCVA, or PVB types), using calibrated gauges. They will tag the device with a test date and their license number. Failed tests due to improper installation require a plumber's return, adding $300–$800 in rework costs.

See All RequirementsProcessing time varies and depends on the scheduling availability for the required physical inspection, which is conducted by the city's Cross-Connection Control Program or an approved tester. After a successful test, submission of the test report to Dallas Water Utilities typically initiates internal review. Contact Dallas Water Utilities to confirm current processing timelines, which can be impacted by other related requirements like obtaining a Building Permit.
The city does not charge a government filing fee for the certification itself, according to the Dallas Water Utilities fee schedule. However, you must pay a licensed, city-approved tester for the on-site inspection and test report. The cost for this service varies by contractor and device type. Not legal advice — verify current costs with Dallas Water Utilities.
No, certifications are site-specific and tied to the installed device and its connection to the public water supply at a given address. A new certification is required for any new business location. This process involves submitting a new application and scheduling an inspection, which is independent of other location-specific permits like a Certificate of Occupancy.
In Dallas, backflow prevention devices must be tested and the certification renewed annually, as mandated by the city's plumbing code. You are responsible for hiring an approved tester and submitting the passing test report to Dallas Water Utilities by the due date. Failure to renew can result in water service interruption and fines.
A city-approved tester will perform a physical and operational test on your installed backflow prevention assembly to ensure it prevents water from flowing backward into the public supply. The tester checks for proper installation, maintenance, and pressure differentials, then completes a standardized test report form. You must submit this official report to Dallas Water Utilities for the certification to be recorded.
