Code-Compliant Backflow Installation in Centreville, VA

Sorting out the plumbing codes for backflow prevention in Centreville, VA can be challenging. FBN Plumbing stays up to date with local and state regulations so every installation is fully compliant. Plumbers in Virginia must hold a state license, and water heater replacements, repiping and sewer work usually need a permit. From proper device selection and placement to required permits and inspections, we handle all aspects of code compliance. Your system works as intended and avoids fines or expensive rework down the line.

Backflow Testing and Certification in Centreville

Most water providers require testable backflow assemblies to be certified at installation and then annually. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Reduced Pressure Zone Assembly Installation in Centreville, VA

RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested easily. We carry proven brands like Watts, Febco, Wilkins and Apollo.

Commercial Backflow Preventer Installation in Centreville

Restaurants, salons, dental offices and light industrial buildings often need multiple backflow devices on soda machines, boilers, dishwashers and process water. We survey the building, identify each cross-connection and install containment and isolation assemblies as required. Work is scheduled after hours or on weekends when needed to keep from shutting down your business. You receive documentation for each device for your records and your water utility.

Pool and Spa Fill Backflow Protection in Centreville, 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 renovated.

Double Check Valve Assembly Installation in Centreville

Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules allow. We size them to avoid too much pressure loss on your system.

Irrigation Backflow Preventer Installation in Centreville

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 layout of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.
