Frequently Asked Questions About Backflow Testing

  • What is backflow testing and why is it required in Virginia Beach?

    Backflow testing is a mandatory plumbing inspection that ensures contaminated water is not flowing backward into your clean, potable water supply. In Virginia Beach and surrounding Hampton Roads cities, regular testing is required by local building codes to prevent cross-connection hazards—such as fertilizers or sewage—from entering the municipal water system. Denny’s Plumbing provides certified testing to keep your home or business compliant with these health regulations.


  • How often do I need to have my backflow preventer tested?

    Most residential and commercial properties in Virginia are required to have their backflow prevention devices tested annually. Local municipalities typically send a notification when your certification is due. Because these devices have internal seals and moving parts that can wear out, yearly inspections are the only way to guarantee your water remains safe for drinking and bathing.


  • What happens during a backflow testing service?

    During a service call, a certified technician from Denny’s Plumbing will shut off your water supply briefly to test the pressure levels of the backflow assembly. We use calibrated gauges to ensure the check valves are preventing back-pressure and back-siphonage effectively. If the device passes, we handle the paperwork and file the certification with the city for you.


  • What are the signs that my backflow preventer is failing?

    While many failures are only detectable through professional testing, some common warning signs include:


    • Visible water leaking from the backflow relief valve.
    • A noticeable drop in water pressure throughout the building.
    • Discolored, rusty, or foul-smelling water coming from your taps.
    • Slow drainage or strange sounds in your pipes. If you notice any of these symptoms, contact Denny’s Plumbing immediately for a diagnostic repair.

  • How much does backflow testing cost in Virginia Beach?

    The cost of backflow testing varies based on the size of the device and whether it is a residential or commercial assembly. Denny’s Plumbing offers competitive, transparent pricing for inspections and certifications. If repairs are needed to pass inspection, we provide a detailed estimate upfront before any additional work begins.


  • Who is authorized to perform backflow testing in Virginia?

    Only licensed plumbers with a specific Backflow Prevention Device Worker certification are authorized to test, repair, or install these devices. The team at Denny’s Plumbing has over 30 years of experience and holds all necessary state and local certifications to ensure your water system meets VDH (Virginia Department of Health) standards.
