Why You Need a Backflow Prevention Device Certification
In Las Vegas, Clark County and the Las Vegas Valley Water District (LVVWD) mandate this certification under the Clark County Ordinance Code Title 20 (Health and Sanitation) and the LVVWD's Cross‑Connection Control Program (Policy No. 1007‑01). These regulations enforce the national plumbing code (UPC) standards locally to protect the public water supply from contamination. The legal requirement is triggered when you apply for a building permit for any new food service facility or a remodel that affects plumbing, or when you receive a notice from the water district for your annual test. Without a current certification on file, the Southern Nevada Health District (SNHD) will not issue your final Certificate of Occupancy or Health Permit.
Failure to obtain and maintain a valid certification carries immediate operational and financial risks. Based on Clark County enforcement actions and SNHD protocols, common penalties include:
- Service Disconnection: The LVVWD can shut off your water service, halting all operations immediately.
- Fines: Daily administrative penalties from Clark County and the SNHD, which can escalate for non‑compliance.
- Required Remediation: You will be ordered to install or repair a device by a licensed plumber and may face mandatory system flushing and water quality testing at your expense.
- Permit & Lease Implications: Your Health Permit can be suspended, violating your lease's operating covenant. Your liability insurance may also be voided if an incident occurs from a non‑certified device.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the Las Vegas Valley Water District now requires electronic submission of all test reports via its designated portal, and the Southern Nevada Health District has integrated this certification status into its online permit verification system for health inspectors.
Who Needs a Backflow Prevention Device Certification?

26 of 31 auto-filledBusiness Address
textEnter the complete street address of the restaurant or commercial kitchen where the backflow device will be installed, as it appears on your business license or lease.
COMMON MISTAKE: Entering a corporate office address, P.O. Box, or the owner's home address instead of the physical service location; this causes immediate rejection.
Water Meter Number
textEnter the unique identifier stamped on your water meter, typically found on your Las Vegas Valley Water District (LVVWD) utility bill or on the meter itself.
COMMON MISTAKE: Entering an account number instead of the meter number or leaving it blank; the department cross-references this number.
Current Water Line Configuration
textDescribe the existing plumbing setup (e.g., 'Direct connection, 1-inch copper main line with a branch to the kitchen'). You may need a plumber's inspection report.
COMMON MISTAKE: Using vague terms like 'normal' or leaving it blank; specific technical descriptions are required for hazard assessment.
Water Connection Point Location
textSpecify the exact physical location where the water service line enters the building (e.g., 'North exterior wall, 3 feet east of the gas meter').
COMMON MISTAKE: Providing an interior location or a room name; inspectors need an external, accessible point for verification.
Restaurant/Food Service Establishment
checkboxCheck this box if your business involves food preparation, commercial cooking, or dishwashing, as this triggers specific device requirements.
COMMON MISTAKE: Leaving it unchecked for a restaurant; this misclassifies the hazard level and leads to an incorrect device specification.
Has Grease Discharge
checkboxCheck this box if your operation has grease interceptors or discharges fats, oils, and grease (FOG) into the sanitary sewer.
COMMON MISTAKE: Incorrectly checking or not checking this box; grease discharge creates a high health hazard requiring a more robust device.
Device Type Confirmed with Water Department
checkboxCheck only after you have received written or verbal confirmation from LVVWD Cross-Connection Control on the exact device model required.
COMMON MISTAKE: Checking this box preemptively before confirmation; this is a certification of compliance and is audited.
Required Device Type
textEnter the specific device model and assembly (e.g., 'Reduced Pressure Principle Assembly, Model RP-1A, 1-inch') as provided by the Water Department.
COMMON MISTAKE: Entering a generic term like 'backflow preventer' or an incorrect model; the installation permit will be denied if the type doesn't match.
Quotes Obtained from Certified Installers
checkboxCheck this box to affirm you have received written cost estimates from installers certified by the Nevada State Board of Plumbing Examiners.
COMMON MISTAKE: Checking the box without having actual quotes from state-certified plumbers; the department may request proof.
Number of Quotes Obtained
textEnter the number of written quotes you have (e.g., '2' or '3'). LVVWD recommends at least two for cost comparison.
COMMON MISTAKE: Entering '0' or '1'; while not a formal rejection cause, it can delay review as they recommend multiple bids.

Top 5 Backflow Prevention Device Certification Mistakes
1. Submitting an Incomplete Test Report
The most common error is submitting the application without the completed, signed, and dated test report from a certified backflow assembly tester. The Southern Nevada Water Authority (SNWA) requires the specific form provided by the purveyor, like the LVVWD's Backflow Prevention Assembly Test Report. Submitting a generic or incomplete form causes an immediate rejection, adding 2–3 weeks as you must re-engage a tester and resubmit.
2. Incorrect or Missing Device Information
Entering a manufacturer/model that doesn't match the device listed on the test report, or failing to provide the device's serial number and installation date, triggers a review delay. For example, listing a 'Watts 009QT' when the tester reported a 'Febco 825Y' creates a mismatch the reviewer must investigate. This often adds 1–2 weeks to your timeline as the authority contacts you or the tester for clarification.
3. Using an Uncertified Tester
Hiring a tester who is not currently certified by the Nevada State Board of Plumbing Examiners and registered with your specific water purveyor (like the Las Vegas Valley Water District) invalidates the entire submission. The application and test report are rejected upon receipt. You must then hire a properly certified tester and pay for a re-test, resulting in a complete restart of the process and costing an additional $150–$300 in testing fees.

Timeline: Varies (Typically 2-8 Weeks)
Step 1: Contact City of Las Vegas Water Department to confirm backflow prevention device requirements for your commercial water connection
Call the City of Las Vegas Water Department's Cross-Connection Control Program at (702) 229-6246 to request a determination of hazard level for your specific operation (e.g., restaurant with dish machine, soda fountain, or irrigation system). Have your business address and a description of all water-using equipment ready. This initial verification is crucial—choosing the wrong device type (like an RPZ vs. a DCV) is the most common reason for failed inspections later. Duration: 1-2 business days.
Step 2: Hire a Nevada-certified backflow prevention device tester/installer (must be on the city's approved contractor list)
Select a contractor from the official list of Approved Backflow Assembly Testers maintained by the Las Vegas Valley Water District. Provide them with the hazard determination from Step 1. Get a written quote detailing the device model (must be USC/ASSE approved), labor, and the separate testing fee they will charge. Most restaurants spend $500-$1,500 for a commercial-grade Reduced Pressure Zone (RPZ) device and installation. Duration: 3-5 business days to schedule.
Step 3: Have the certified professional install an approved backflow prevention device on your water line
The contractor installs the specific device per the manufacturer’s specifications and city code (e.g., City of Las Vegas Municipal Code Title 13). They must ensure proper clearances (typically 12-18 inches from walls), orientation, and drainage for relief valves. You need to be present to provide access and pay the installer directly upon completion. Keep the device's model/serial number paperwork for your records. Duration: 1 day for installation.

See All RequirementsProcessing timelines vary significantly and are not publicly standardized by the authority, as stated on the Las Vegas Valley Water District (LVVWD) website. The time depends on inspector availability, the testing company's schedule, and the completion of any required corrective work. Contact the LVVWD's Cross-Connection Control Program to confirm current wait times before starting other projects like your Building Permit.
There is no direct government filing fee to submit the certification test report to the Las Vegas Valley Water District. Your primary cost is hiring a state-certified backflow prevention assembly tester, which typically ranges from $75 to $200 per device, according to local service providers. Not legal advice — verify specific testing requirements and any potential administrative fees directly with the LVVWD.
No, certifications are specific to the device installed at a particular address and are not transferable. A new location requires a new device installation, inspection, and certification test. This is a separate process from transferring a City Business License/Registration, per the LVVWD's Cross-Connection Control rules.
You must renew certification annually, as mandated by the Las Vegas Valley Water District's regulations. A state-certified tester must perform the test and submit the report to the LVVWD each year. Missing the annual deadline can result in water service disruption, so schedule the test well in advance of your expiration date.
A certified tester will verify the device is the correct type for the hazard level, check for proper installation (including orientation and clearance), and perform a functional test to ensure it prevents backflow under pressure conditions. They will document any failures or required repairs and submit the official test report directly to the water district on your behalf.
