Irrigation Backflow Preventer Installation in Leesburg
Landscape irrigation is the most common reason homeowners need a backflow device. Fertilizer, herbicides and stagnant water in sprinkler and drip lines can be siphoned into your drinking water if pressure drops. We install pressure vacuum breakers or double check assemblies based on local requirements and the design of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.

Backflow Preventer Installation Cost Comparison in Leesburg, VA
A residential pressure vacuum breaker is the most affordable option, while larger RPZ assemblies for commercial buildings cost a good deal more in parts and labor. Size, brand, enclosure needs and how much existing pipe must be modified all affect the price. Replacing a failed old device with a new one is often cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.
Pool and Spa Fill Backflow Protection in Leesburg, VA
An auto-fill line or hose connection on a pool or spa creates a straight path for chlorinated water to reach the supply. We install the correct device on pool fill lines and check that hose bibbs have vacuum breakers. This simple step protects your household water and keeps you in line with local code. We can add the work when a pool is being built or remodeled.
Backflow Preventer Brands We Install in Leesburg
FBN Plumbing works with leading backflow preventer brands known for reliability and durability. We commonly install devices from manufacturers such as Watts, Wilkins by Zurn, Apollo and Conbraco. Our experience with these brands means you receive a high-quality, long-lasting solution built to handle the water conditions and pressures in Leesburg plumbing systems. We can also advise on models that best fit your budget and application.
Backflow Enclosures and Freeze Protection in Leesburg, VA
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Higher elevations in the west of Virginia freeze more often and harder than coastal areas, so pipe insulation matters more there. We install insulated enclosures, freeze blankets or heated cabinets based on your location. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and service.
