Double Check Valve Assembly Installation in Stockton
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.

Reduced Pressure Zone Assembly Installation in Stockton, 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 Stockton
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.
Reduced Pressure Zone (RPZ) Assembly Installation in Stockton
RPZ assemblies offer the highest level of backflow protection and are often required for high-hazard applications in Stockton. 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.

Frequently Asked Questions About Backflow Preventer Installation in Stockton
Residential pressure vacuum breakers usually 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.
Backflow preventers are installed at cross-connection points where non-potable water could enter the potable water supply. Common locations include irrigation system connections, fire sprinkler lines, boiler systems and connections to auxiliary water supplies, often just after the main water meter or at the point of hazard.
Yes, FBL Plumbing stands behind our work. We offer a warranty on our backflow preventer installations, covering both the workmanship and the installed device. Specific warranty details will be included with your quote and invoice, giving you peace of mind.
Most municipalities require annual testing of backflow preventers by a licensed, certified backflow tester. This confirms the device is working correctly and continues to protect your potable water supply from contamination. We can also help with scheduling these annual tests.
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.
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 can also point to broader plumbing issues as well.
Installing a backflow preventer is a complex task that requires plumbing knowledge, tools and certification to meet local codes and properly 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 FBL Plumbing.
You likely need a backflow preventer if you have an irrigation system, a fire sprinkler system, a swimming pool or any auxiliary water source that connects to the main water supply. Local regulations in Stockton often require these devices for certain applications to protect public health.
