Virginia state law and local municipal ordinances mandate that all commercial backflow preventers, residential irrigation backflow valves, fire sprinkler systems, and boilers undergo annual testing by a certified backflow device worker.

Installing a new backflow preventer requires proper sizing, correct orientation, and strict adherence to Virginia Uniform Statewide Building Code (USBC) clearance requirements.
A failing backflow preventer can dump hundreds of gallons of water, cause severe pressure drops, or expose your drinking water to hazardous pollutants.
At Backflow Services Done Right (operated by Baumbach Plumbing & Remodeling), we have spent nearly a century protecting public health and clean water supplies across Northern Virginia. If you own a home, manage an HOA, or oversee commercial real estate in Alexandria, maintaining a properly functioning backflow preventer is both a safety necessity and a legal obligation under the Virginia State Plumbing Code.
Because Alexandria’s potable water distribution is managed primarily by Virginia American Water, with wastewater handled through AlexRenew (Alexandria Renew Enterprises), property owners must comply with strict cross-connection control guidelines.
Whether you received an annual testing notice from Virginia American Water, need a new Reduced Pressure Zone (RPZ) assembly installed for a commercial irrigation system, or require emergency repair for a leaking device, our licensed technicians deliver prompt, flat-rate solutions. We service all residential and commercial properties throughout Alexandria, including Old Town, Del Ray, Rosemont, Carlyle District, Potomac Yard, Arlandria, Alexandria West, and along the Mount Vernon Highway corridor.
Different property hazards require specific backflow prevention technology. Our DPOR-certified technicians are qualified to test and service every approved device design:
| Device Type | Common Application | Hazard Classification |
|---|---|---|
| Reduced Pressure Zone (RPZ) | Commercial Buildings, Boilers, Medical | High Hazard (Health Hazard) |
| Double Check Valve Assembly (DCV) | Indoor Plumbing, Low Hazard Systems | Low Hazard (Non-Health) |
| Pressure Vacuum Breaker (PVB) | Residential & Commercial Lawn Sprinklers | High Hazard (Outdoor Siphonage) |
| Atmospheric Vacuum Breaker (AVB) | Hose Bibbs, Point-of-Use Fixtures | Low to Medium Hazard |
The ultimate defense against high-hazard contamination. Equipped with two independent check valves and a hydraulically operated relief valve, RPZs are mandatory for commercial kitchens, chemical lines, multi-story buildings, and high-risk irrigation systems.
Comprising two spring-loaded check valves, DCVs are typically installed underground or indoors for low-hazard applications where non-toxic pollutants could enter the water line.
The standard choice for residential and commercial irrigation systems. PVBs prevent backsiphonage caused by sudden loss of municipal water pressure.
Physical non-mechanical and point-of-use barriers installed on specialized plumbing fixtures and supply connections.

Yes. Virginia State Plumbing Code and Virginia Department of Health (VDH) regulations mandate annual testing for all containment backflow devices connected to public water supplies. Virginia American Water enforces annual testing to ensure contaminants do not siphoned back into Alexandria’s clean drinking water system.
If your backflow preventer fails due to a leaking check valve or a sticking relief valve, the utility will issue a deadline to complete repairs. Our technicians carry OEM rebuild kits in their service vehicles and can perform most repairs and re-tests on the same day to keep your property compliant.
Standard residential backflow testing in Alexandria generally ranges between $85 and $160, depending on the device type, size, and location accessibility. Commercial testing prices depend on valve diameter (e.g., 2-inch to 8-inch RPZ assemblies). Contact us today for an exact, transparent quote.
We handle all paperwork for you! Once your backflow assembly passes inspection, our team completes the official state test form and submits it directly to Virginia American Water and local Alexandria municipal water departments on your behalf.
Irrigation systems should be tested upon seasonal startup each spring before placing the water line under continuous pressure. Running an untested or winter-damaged backflow valve risks introducing stagnant water, fertilizers, or pesticides into your home’s drinking water.
