We handle everything from small residential devices to bigger systems.
Reduced Pressure Zone Assembly Installation in Rialto, 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 proven brands like Watts, Febco, Wilkins and Apollo.
Backflow Testing and Certification in Rialto
Most water providers require testable backflow assemblies to be certified at installation and then once a year. 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 (DCVA) Installation in Rialto
The double check valve assembly, or DCVA, is a common backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Rialto, 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.
Commercial Backflow Prevention in Rialto, CA
Commercial properties in Rialto, 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 full 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.

Reduced Pressure Zone (RPZ) Assembly Installation in Rialto

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.
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.
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 Rialto often require these devices for certain applications to protect public health.
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 water providers require testable assemblies to be tested at installation and then every year. Some high hazard facilities may be tested more often.
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, call us for an inspection in Rialto.
