Reduced Pressure Zone (RPZ) Device Installation in Temecula, CA
For high-hazard applications in Temecula, 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.

Irrigation Backflow Preventer Installation in Temecula
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.
Pressure Vacuum Breaker (PVB) Installation in Temecula, CA
For low-hazard applications, such as lawn irrigation systems in Temecula, CA, a pressure vacuum breaker, or PVB, is a popular and cost-effective backflow prevention device. PVBs protect against back-siphonage by letting air into the system when pressure drops. Our certified plumbers expertly install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also check for proper clearance and drainage.
Reduced Pressure Zone Assembly Installation in Temecula, 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.
Backflow Prevention for Irrigation Systems in Temecula, CA
Irrigation systems in Temecula, CA are a frequent source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply. Installing a dedicated backflow preventer for your sprinkler system is often a local code requirement. We are experienced in selecting and installing the correct device, such as a pressure vacuum breaker or atmospheric vacuum breaker, to protect your home's main water line from contaminants introduced by your landscape irrigation.
Commercial Backflow Prevention in Temecula, CA
Commercial properties in Temecula, CA often have complex plumbing systems that pose a higher risk of cross-contamination and require robust backflow prevention. Restaurants, hospitals, industrial facilities and even multi-family buildings must comply with commercial plumbing codes. FKM Plumbing provides complete installation of heavy-duty backflow preventers, including large diameter RPZ assemblies, to safeguard public health and meet Southern California regulations for businesses. We handle all necessary permits and inspections.
Double Check Valve Assembly (DCVA) Installation in Temecula
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 Temecula, DCVAs are frequently 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.

Double Check Valve Assembly Installation in Temecula
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.
