Backflow Testing & Inspections

Backflow testing and inspections are the cornerstone of potable water protection. At Oh No Backflow, LLC, our state-certified backflow inspector performs accurate, compliant testing and thorough inspections for residential and commercial properties across Georgia. Our testing services verify that backflow prevention assemblies operate properly and provide the official documentation required by municipalities and state regulators.

Why Backflow Testing Matters

Backflow testing ensures that mechanical assemblies designed to prevent contaminated water from entering the clean water supply are functioning correctly. These devices can fail due to wear, stress, mineral buildup, or improper installation. Municipalities typically require annual testing to reduce the risk of contamination. Failing to test or address test failures can lead to public health hazards, fines, and plumbing system interruptions.

What We Test

  • Reduced Pressure Zone Assembly (RPZ/RPDA)
  • Double Check Valve Assembly (DCVA)
  • Pressure Vacuum Breaker (PVB)
  • Atmospheric Vacuum Breaker (AVB)
  • Hose Bibb and residential backflow preventers
  • Irrigation system backflow assemblies
  • Commercial multi-assembly systems

How Our Testing Process Works

01

Pre-Visit Intake

We collect property information, number and location of assemblies, last test date, and any prior test reports to prepare for the on-site visit.

02

Arrival and Site Coordination

Our certified technician conducts a brief intake, confirms access, and outlines the testing process. For commercial sites, we coordinate with facility management to minimize disruption.

03

Visual Inspection

Technician inspects each assembly for corrosion, physical damage, leaks, and signs of improper installation or tampering.

04

Functional Testing

Using calibrated test gauges and state-approved procedures, the technician performs step-by-step tests to evaluate valve seating, relief valve operation, and check valve performance.

05

Test Results and Documentation

Results are recorded on the official state test form and delivered to you in digital and printable formats. We submit municipal-required copies upon request.

06

Recommendation and Immediate Actions

If the assembly passes, we recommend routine maintenance and schedule reminders for annual testing. If it fails, we provide a clear diagnosis, repair estimate, or replacement recommendation.

Common Reasons Assemblies Fail Testing

  • Worn or damaged seals and seats
  • Debris or mineral deposition in the valves
  • Damaged or corroded springs and moving parts
  • Improper installation or incorrect device orientation
  • Water pressure issues causing unusual loading
  • Physical damage due to freezing or impact

Residential vs Commercial Testing

  • Residential: Most residential tests are straightforward but require careful access, typically around irrigation systems, pool fills, or external fixtures. Homeowners benefit from clear explanations of failure causes and homeowner-friendly repair options.
  • Commercial: Commercial sites may have multiple assemblies, larger devices, or assemblies in mechanical rooms requiring coordination. We provide tailored testing schedules and work with facility management to meet regulatory deadlines.

Documentation and Compliance

Following every inspection, we provide:



- Completed state test forms

- Electronic copies delivered by email

- Print-ready certificates for municipal submission

- Explanatory notes on any observed issues and recommended next steps

Annual Testing and Maintenance Plans

We offer annual testing plans that include scheduled reminders, priority scheduling, and discounted rates for recurring testing contracts. These plans prevent missed tests, reduce failure risk, and protect your property from non-compliance penalties.

Emergency Testing and Rapid Response

If you suspect contamination, receive a failed-test notice, or have an urgent backflow problem, our emergency team is available 24/7. We'll perform immediate testing, isolate the problem, and implement temporary measures or repairs to protect your water supply.

Why Choose Our Certified Inspector

  • State certification ensures that tests are performed to regulatory standards.
  • Calibrated and well-maintained testing equipment for reliable results.
  • Prompt delivery of official paperwork to satisfy municipal requirements.
  • Knowledgeable technicians who explain results and offer pragmatic solutions.

Cost Considerations

Backflow testing costs vary by device type and accessibility. We provide transparent pricing before arrival and detailed invoices upon completion. If repairs are required, we provide clear repair estimates and work only after your approval.

Preparing for Your Test Appointment

  • Ensure clear access to the assembly location (e.g., remove obstructions, unlock gates).
  • For commercial properties, designate a point of contact and ensure any necessary permits or access cards are available.
  • If device tags or prior test reports exist, provide them to speed processing.

What Happens If a Device Fails?

  • We will secure the system as needed to prevent contamination.
  • Offer immediate repair options if feasible or provide replacement recommendations.
  • Provide documentation of the failed test and the corrective action taken for municipal records.

Frequently Asked Questions

  • How often should testing occur?

    Annual testing is typically required; some jurisdictions may require more frequent testing for certain systems.

  • Will testing interrupt my water service?

    In most cases, testing may temporarily affect the area of the assembly but is typically non-invasive and brief. For larger assemblies, coordination may be needed for minimal disruption.

  • Can you submit the test report to the city?

    Yes, we can submit required paperwork to municipal authorities on request.

  • What if I don’t know my device type?

    Our technician can identify your assembly and recommend the appropriate testing and next steps.
