Why You Need a Backflow Prevention Device Certification
In Reno, a Backflow Prevention Device Certification is required under the City of Reno Municipal Code, specifically Title 15 – Water, and is enforced by the Truckee Meadows Water Authority (TMWA). The regulations mandate that any commercial facility with a water service connection that poses a potential cross-connection hazard—such as a restaurant—must install, test, and annually certify an approved backflow prevention assembly. This is to protect the public water supply from contamination by backflow of non-potable water, which could contain grease, chemicals, or other contaminants from your kitchen plumbing system. The specific device type and installation requirements are detailed in TMWA's Cross-Connection Control Program Manual, available on their website.
Operating without a current, approved certification carries significant consequences. Based on TMWA's enforcement protocols and local ordinances, the penalties include:
- Fines and service fees: Monetary penalties for non-compliance, which escalate for repeat offenses. The initial notice typically includes a fee for re-inspection and administrative costs.
- Water service disconnection: TMWA has the authority to terminate your water service until the device is certified, effectively shutting down your restaurant.
- Required emergency remediation: If backflow contamination occurs, you become liable for the cost of flushing and testing the public water lines, which can run into thousands of dollars.
- Insurance and lease violations: Many commercial property leases and business insurance policies require proof of compliance with all municipal codes. Failure to provide your annual certification can breach your lease or invalidate your coverage.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, TMWA has fully implemented its online portal for test report submission, requiring all certified testers to file results electronically within 10 business days of the test.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required due to direct connection of dishwashers, ice machines, or other equipment to the potable water supply, as defined by Reno Municipal Code (RMC) Title 12 and the Uniform Plumbing Code. |
| Bar / Nightclub | Required | Required due to the installation of soda guns, post-mix systems, glasswashers, or ice machines that create a direct cross-connection hazard with the public water system. |
| Food Truck | Not Required | Typically not required as a standalone vehicle permit; backflow prevention for the commissary or water fill station is the responsibility of the base kitchen's facility permit. |
| Coffee Shop / Café | Required | Required if the espresso machine, hot water boiler, or commercial ice maker is directly plumbed, creating a potential cross-connection per RMC Title 12. |

27 of 32 auto-filledBusiness Name
textEnter the full legal name of your restaurant business, exactly as it appears on your Articles of Incorporation, LLC filing, or DBA registration with the Nevada Secretary of State.
COMMON MISTAKE: Entering a trading name ('Joe's Diner') or the owner's personal name instead of the registered legal entity name, which will result in a rejection for non-matching records.
Business Type
textSpecify your business's legal structure: e.g., 'Limited Liability Company (LLC)', 'Corporation', 'Sole Proprietorship', or 'Partnership'.
COMMON MISTAKE: Using vague terms like 'Restaurant' or 'Food Service'; the form requires the formal legal entity type to determine liability and billing.
Owner Name & Title
textProvide the full name and official title (e.g., 'President', 'Managing Member', 'Owner') of the person authorized to sign for the business.
COMMON MISTAKE: Omitting the required title, or listing a non-signing manager; the signatory must have legal authority to bind the company.
Phone Number
textEnter a direct, working phone number for the primary business contact, including area code, in the format (XXX) XXX-XXXX.
COMMON MISTAKE: Providing a disconnected number, a personal cell without voicemail, or a number for a different location, which delays inspector communication.
Email Address
textProvide a valid, monitored business email address where official correspondence and the test report can be sent.
COMMON MISTAKE: Using a personal or outdated email, which causes missed notifications and document requests from the Truckee Meadows Water Authority (TMWA).
TMWA Account Number
textEnter your exact, active account number with the Truckee Meadows Water Authority (TMWA) for the water service at this facility.
COMMON MISTAKE: Confusing this with a City of Reno utility account, using an old or closed account number, or leaving it blank because service is new—TMWA requires this to cross-reference your meter.
Water Service Address
textProvide the complete street address where TMWA water service enters the property, which must match the address on your TMWA account.
COMMON MISTAKE: Listing a mailing address, a parcel/APN number, or the restaurant's front door if the water meter is elsewhere on the property, causing a data mismatch with TMWA records.
Existing Backflow Device
checkboxCheck this box only if a backflow prevention assembly is already installed and operational on the water service line for this address.
COMMON MISTAKE: Incorrectly checking 'yes' for a planned but not yet installed device, which triggers an immediate demand for a test report you cannot provide.
Facility Address
textEnter the complete physical address of the restaurant facility, including suite or unit number, which must be within Reno's jurisdiction.
COMMON MISTAKE: Providing an address outside Reno city limits, or using a P.O. Box; the address must be verifiable for zoning and inspection purposes.
Building Plans Available
checkboxCheck this box if you have, or can obtain, scaled building plans that show the plumbing layout and intended location for the backflow device.
COMMON MISTAKE: Checking 'yes' without actually having plans, leading to a request for document submission you cannot fulfill and stalling the review.

Top 5 Backflow Prevention Device Certification Mistakes
1. Missing or Improper Test Report
Submitting a test report from a technician who is not on the City of Reno's approved tester list is the #1 cause of immediate rejection. The report must be on the official city form, not a generic template, and include all required data points like static and differential pressure readings. Using an unapproved tester or an incomplete form adds 3–4 weeks to your timeline for retesting and resubmission.
2. Incorrect Device Location or ID Number
Entering a vague location like 'near the kitchen' or transposing digits in the device's serial/model number triggers a review halt. Inspectors need the precise location (e.g., '3 feet east of water meter vault, adjacent to back alley gate') and the exact ID stamped on the device to verify the report. This mistake typically adds 10–14 days of back-and-forth clarification delays.
3. Submitting an Out-of-Date Test
Reno requires the test to be performed within 30 days of application submission. Applicants often submit a report from a prior year's annual test or one that is just over the 30-day window. The consequence is automatic rejection, requiring a brand new test and fee payment, which sets the approval back by a full month.

Timeline: A Multi-Week Process from Scheduling to Submission
Step 1: Contact Truckee Meadows Water Authority (TMWA) to confirm backflow prevention device requirements for your commercial water connection
Call TMWA's commercial services line (775-834-8095) or review their online commercial water connection guidelines to determine your specific device type (RPZ, DCVA, etc.) and installation location based on your water use and fire suppression system. This prevents ordering the wrong device, which adds 1-2 weeks for returns and re-ordering.
Step 2: Hire an approved backflow tester from the TMWA Approved Backflow Testers list
Download the current Approved Backflow Assembly Testers list from the TMWA website—testing must be performed by a name on this list to be valid. Get quotes from 2-3 testers; rates range from $150–$400 for the initial test. Schedule for a date after your device is installed but before you need final water approval.
Step 3: Schedule backflow prevention device inspection and testing with the approved tester
Coordinate with your plumber to ensure the device is fully installed and accessible before the tester arrives. The tester will perform a physical inspection and a pressure test, which takes 45–90 minutes on-site. Have your property address, TMWA account number, and device manufacturer/model information ready.

See All RequirementsProcessing timelines vary significantly based on contractor and city inspector availability. The testing itself is quick, but scheduling the mandatory inspection with the City of Reno's Public Works Department can add weeks. According to the city's application guide, you should plan for a multi-week process from hiring a certified tester to receiving your certification.
The City of Reno does not charge a government filing fee for the certification itself. However, you must pay a state-certified backflow prevention assembly tester for the test and any required repairs. Contact the City of Reno Public Works to confirm there are no administrative fees and verify the current list of approved testers.
No, certifications are site-specific and device-specific, tied to the physical address and plumbing configuration. A new location requires a new test and certification. This process is similar to needing a new Building Permit or Electrical Permit for major changes—the approval follows the property.
In Reno, most commercial backflow prevention devices must be tested and re-certified annually, as mandated by the Reno Municipal Code. The specific renewal date is set by the city based on your initial test. Failure to renew can result in water service interruption, so it's a critical recurring task, similar to renewing your City Business License/Registration.
A state-certified tester will perform a pressure test on your device to ensure it prevents contaminated water from flowing backward into the public supply. They will check for proper installation, leaks, and functionality. The tester then submits the test report directly to the City of Reno Public Works for review and official certification.
