Irrigation Backflow Preventer Installation in Florence-Graham
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the required height. Insulated covers or enclosures help protect it from weather damage and theft.
Reduced Pressure Zone Assembly Service in Florence-Graham, CA
RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems. They have two check valves and a relief port that discharges water if a check fails. We install, test and rebuild RPZ units from Watts, Febco, Wilkins and Apollo. Proper drainage is designed for the relief port discharge.
Commercial Backflow Services in Florence-Graham, CA
Businesses in Florence-Graham often have more complex backflow prevention requirements due to higher water usage and diverse plumbing systems. FKM Plumbing provides full-service commercial backflow services, including large-scale testing, repair, and installation for multi-unit properties, industrial facilities, and restaurants.

Febco Backflow Preventer Experts in Florence-Graham
Febco backflow preventers are commonly found in commercial and irrigation applications. FKM Plumbing provides professional service for all Febco models, including the 825Y and 860 series.

Trust us to maintain your Febco device to factory specifications so it keeps protecting against backflow events.
Backflow Preventer Repair and Rebuild in Florence-Graham, CA
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly. We isolate the assembly, disassemble it and replace the worn parts with the manufacturer rebuild kit. Then we retest to verify it passes. Rebuilding usually costs far less than replacing the entire assembly.
Freeze and Heat Protection for Backflow Preventers in Florence-Graham, CA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Freezing pipes are rare in most of Southern California, and many homes have exposed outdoor plumbing that would never pass in a harsher climate. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last for years.

Backflow Preventer Cost & Value in Florence-Graham, CA
The cost of backflow preventer services in Florence-Graham, CA varies depending on the type of service, such as testing, repair, or installation, and the device involved. While there is an upfront investment, a working backflow preventer provides important protection for your health and avoids potential fines or costly contamination cleanup. We offer clear pricing and detailed estimates before any work begins.
