Proper backflow assembly installation requires exact valve selection, accurate pipe sizing, freeze protection, and strict adherence to local spatial clearance codes.
When a backflow device leaks continuously from its relief port or fails its annual inspection, prompt repair prevents water waste, pressure loss, and non-compliance penalties.
At Backflow Services Done Right (operated by Baumbach Plumbing & Remodeling), our family-owned plumbing company has protected Northern Virginia drinking water systems for nearly a century. Whether you manage a commercial facility along the Dulles Technology Corridor, own a retail storefront on Elden Street (Route 228), or live in a single-family home with a lawn irrigation system in Fox Mill or Kingston Chase, maintaining a functional backflow preventer is vital for public health and local municipal compliance.
Potable drinking water across Herndon is distributed through Fairfax Water (working in coordination with Town of Herndon public works), which mandates annual inspection and testing for all containment backflow devices in accordance with the Virginia Uniform Statewide Building Code (USBC) and local cross-connection control regulations.

Different plumbing hazards require specific backflow assembly designs. Our DPOR-certified specialists are qualified to service all code-approved devices:
| Device Type | Primary Application | Hazard Level |
|---|---|---|
| Reduced Pressure Zone (RPZ) | Commercial Buildings, Boilers, High-Risk Systems | High Hazard (Health Hazard) |
| Double Check Valve Assembly (DCV) | Indoor Plumbing, Low-Hazard Fire Lines | Low Hazard (Non-Health) |
