Backflow Preventer Brands We Install in Antioch
FBL 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 withstand the water conditions and pressures in Antioch plumbing systems. We can also advise on models that best fit your budget and application.

Reduced Pressure Zone Assembly Installation in Antioch, CA
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.
Irrigation Backflow Preventer Installation in Antioch
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.
Emergency Backflow Preventer Replacement in Antioch
While installations are typically planned, sometimes an existing backflow preventer fails suddenly, creating an urgent need for replacement in Antioch. A compromised backflow device can lead to immediate contamination risks or code violations. FBL Plumbing offers emergency replacement service to promptly assess the situation, remove the faulty unit and install a new, code-compliant backflow preventer, restoring your water safety as quickly as possible.
Double Check Valve Assembly (DCVA) Installation in Antioch
The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Antioch, DCVAs are often installed on fire sprinkler systems or irrigation lines. Our certified plumbers precisely install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.
Commercial Backflow Preventer Installation in Antioch
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 avoid shutting down your business. You receive documentation for each device for your records and your water utility.
Reduced Pressure Zone (RPZ) Assembly Installation in Antioch
RPZ assemblies offer the highest level of backflow protection and are often required for high-hazard applications in Antioch. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. FBL Plumbing specializes in precise RPZ installation, with proper sizing, placement and testing to meet all regulatory requirements for residential and commercial properties. We work with trusted brands like Watts and Febco.

Double Check Valve Assembly Installation in Antioch
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 excessive pressure loss on your system.

An RPZ, or reduced pressure zone device, provides the highest level of protection and is used for high-hazard applications where contaminants could be toxic. A DCVA, or double check valve assembly, is used for low-hazard applications where contaminants are non-toxic. The choice depends on the risk of contamination at the cross-connection point.
