Installing a backflow assembly in high-density Arlington urban environments requires precise layout design, adequate clearance, and full compliance with county plumbing codes.
A broken or leaking backflow preventer can result in significant water waste, low pressure, or non-compliance fines from county inspectors.
At Backflow Services Done Right (operated by Baumbach Plumbing & Remodeling), our family-owned company has served Northern Virginia homeowners, condominium boards, and commercial facility managers since 1928. A properly maintained backflow preventer is critical for preventing contaminated water from reversing flow into your property’s plumbing fixtures or the municipal public water supply.
Water distribution in Arlington is overseen by the Arlington County Department of Environmental Services (DES),
which enforces strict Cross-Connection Control Program standards pursuant to the Virginia Uniform Statewide Building Code (USBC). Properties equipped with lawn irrigation systems, commercial cooling towers, fire suppression lines, or multi-story plumbing systems receive annual backflow inspection notices from county authorities. Whether you need an annual compliance report filed for a residential property along the Columbia Pike corridor, a heavy-duty Reduced Pressure Zone (RPZ) device installed for a commercial kitchen in Clarendon, or emergency valve repairs in National Landing / Crystal City, our certified technicians provide transparent, flat-rate solutions.
We service all urban hubs and residential neighborhoods across Arlington, including Rosslyn, Ballston, Clarendon, Courthouse, Crystal City, Pentagon City, Shirlington, Lyon Village, Cherrydale, Fairlington, and East Falls Church.
Different plumbing hazards require specific backflow prevention technology. Our DPOR-certified specialists are licensed to test, install, and repair every code-approved assembly type:
| Assembly Type | Common Arlington Application | Hazard Level |
|---|---|---|
| Reduced Pressure Zone (RPZ) | Commercial Kitchens, Boilers, Medical, High-Rises | High Hazard (Health Hazard) |
| Double Check Valve Assembly (DCV) | Indoor Commercial Plumbing, Low Hazard Fire Lines | Low Hazard (Non-Health) |
| Pressure Vacuum Breaker (PVB) | Residential Lawn Sprinklers, Commercial Irrigation | High Hazard (Outdoor Siphonage) |
| Atmospheric Vacuum Breaker (AVB) | Janitorial Sinks, Hose Bibbs, Point-of-Use | Low to Medium Hazard |

The highest level of mechanical protection available. RPZs feature two independent check valves and an intermediate hydraulically operated differential relief valve, making them mandatory for commercial facilities, multi-story buildings, and high-risk applications.

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.

Designed specifically to prevent backsiphonage on lawn irrigation and landscape sprinkler lines across Arlington residential properties.
