Double Check Valve Assembly Installation in Los Angeles
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 permit. We size them to avoid excessive pressure loss on your system.

Backflow Preventer Brands We Install in Los Angeles
FKM Plumbing works with leading backflow preventer brands known for reliability and durability. We regularly 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 Los Angeles plumbing systems. We can also recommend models that best fit your budget and application.
Reduced Pressure Zone Assembly Installation in Los Angeles, 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. We carry trusted brands like Watts, Febco, Wilkins and Apollo.
Backflow Preventer Installation Cost Comparison in Los Angeles, CA
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 usually cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.

Frequently Asked Questions About Backflow Preventer Installation in Los Angeles
The cost for backflow preventer installation in Los Angeles, CA can range from about $300 to $1,500, depending on the type of device required, such as a DCVA or an RPZ, the complexity of the installation and any changes needed to existing plumbing. Commercial installations with larger devices may cost more. We provide a detailed, upfront quote after an on-site assessment.
We regularly install high-quality backflow preventers from trusted brands such as Watts, Wilkins by Zurn, Apollo and Conbraco. Our plumbers are experienced with a wide range of devices and can recommend the right option for your application and budget.
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.
Most manufacturers offer one to five year warranties depending on the model. We also warranty our installation labor and will review the coverage with you.
It depends on the hazard and local rules. Irrigation usually uses a PVB or double check, while high hazard connections like commercial kitchens or chemical injection require an RPZ.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are typical signs. Visible corrosion or a cracked body from freezing also means service is needed.
Most residential backflow preventer installations can be finished within 2 to 4 hours. More complex commercial installations or those requiring extensive pipe changes might take a full day. We always aim for prompt service with minimal disruption to your water supply.
Backflow is when water flows the wrong way through a pipe and carries contaminants into the clean water supply. It can happen from back siphonage during a pressure drop or back pressure from pumps and other equipment.
