Double Check Valve Assembly (DCVA) Installation in Compton
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 Compton, 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.

Backflow Enclosures and Freeze Protection in Compton, CA
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. On an occasional cold night, covering backflow preventers and outdoor valves is typically enough to avoid a break. 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.
Double Check Valve Assembly Installation in Compton
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.
Understanding Backflow Preventer Installation Costs in Compton, CA
The cost of backflow preventer installation in Compton, CA varies with the device type, size, location and complexity of the plumbing changes required. A residential irrigation system and a large commercial water main will be priced very differently. FKM Plumbing provides transparent, upfront quotes after a thorough assessment of your property. We aim to offer fair pricing for high-quality, code-compliant installations that protect your investment and health.
Reduced Pressure Zone (RPZ) Device Installation in Compton, CA
For high-hazard applications in Compton, CA where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is usually required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. FKM Plumbing is experienced with RPZ installation, making sure all components are correctly sized, positioned and set up according to state and local plumbing codes. Proper installation is essential for effective operation.
Reduced Pressure Zone (RPZ) Assembly Installation in Compton
RPZ assemblies offer the highest level of backflow protection and are commonly required for high-hazard applications in Compton.

FKM 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.

Frequently Asked Questions About Backflow Preventer Installation in Compton
Residential pressure vacuum breakers typically cost $250 to $700 installed. Double check and RPZ assemblies for larger homes or businesses range from $800 to $3,500 or more depending on size and enclosure needs.
We commonly 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.
Backflow preventers are usually installed as a preventive measure or because code requires them. Signs of possible cross-contamination include discolored or foul-smelling tap water, unexplained drops in water pressure or visible dirty water entering a clean water source, though these often point to broader plumbing issues as well.
FKM Plumbing stands behind our work with a comprehensive warranty on our backflow preventer installations. This warranty covers both the labor and the installed device, providing you with peace of mind. Specific warranty details will be included with your quote.
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.
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 boilers.
Installing a backflow preventer is a complex task that requires plumbing knowledge, tools and certification to meet local codes and effectively protect your water supply. Incorrect installation can lead to ineffective protection, fines or health risks. It is always recommended to hire a licensed professional like FKM Plumbing.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are common signs. Visible corrosion or a cracked body from freezing also means service is needed.
