Irrigation Backflow Preventer Installation in Fullerton
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.

Backflow Prevention for Irrigation Systems in Fullerton, CA
Irrigation systems in Fullerton, 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.
Backflow Testing and Certification in Fullerton
Most water providers require testable backflow assemblies to be certified at installation and then annually. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.
Double Check Valve Assembly Installation in Fullerton
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.
Code-Compliant Backflow Installation in Fullerton, CA
Sorting out the plumbing codes for backflow prevention in Fullerton, CA can be challenging. FKM Plumbing stays up to date with local and state regulations so every installation is fully compliant. Plumbing work in Southern California follows the statewide plumbing code, which is based on the Uniform Plumbing Code with state amendments. From proper device selection and placement to required permits and inspections, we handle every part of code compliance. Your system works as intended and avoids fines or costly rework down the line.
Residential Backflow Preventer Installation in Fullerton
For homeowners in Fullerton, protecting your family's drinking water is paramount. We install many types of backflow preventers, often required for irrigation systems, fire suppression lines or properties with alternative water sources. Our plumbers will assess your home's plumbing layout to recommend the right device, meeting local health department regulations and protecting your potable water supply. We handle everything from small residential devices to bigger systems.
Pressure Vacuum Breaker (PVB) Installation in Fullerton, CA
For low-hazard applications, such as lawn irrigation systems in Fullerton, CA, a pressure vacuum breaker, or PVB, is a common 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.

Backflow Preventer Installation Cost Comparison in Fullerton, 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 Fullerton
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.
Most residential installs take two to four hours including testing. Large commercial assemblies can take a full day, especially if piping must be reconfigured.
Most municipalities require annual testing of backflow preventers by a licensed, certified backflow tester. This verifies the device is working correctly and continues to protect your potable water supply from contamination. We can also assist with scheduling these annual tests.
Signs of a failing backflow preventer include discolored or foul-smelling water, a noticeable drop in water pressure, visible leaks around the device or water discharging from the relief valve on an RPZ. If you notice any of these, contact us for an inspection in Fullerton.
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.
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.
You probably 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 Fullerton often require these devices for certain applications to protect public health.
Most water providers require testable assemblies to be tested at installation and then annually. Some high hazard facilities may be tested more often.
