Annual Backflow Testing in Pomona
Most water providers require backflow assemblies to be tested at least once a year. Our certified testers connect a calibrated differential pressure gauge and check each check valve and relief valve. Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are done until next year.

Backflow Repair vs. Replacement Cost in Pomona, CA
Repairing a failed assembly with a rebuild kit is often the most economical choice.

You choose the option that fits your budget and compliance needs.

Freeze and Heat Protection for Backflow Preventers in Pomona, CA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Mountain and high desert communities in Southern California do get hard freezes, so pipes there need insulation and proper winter care. 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 Installation in Pomona
Whether you are installing an irrigation system, a fire suppression line, or require a new backflow preventer for your domestic water supply, FKM Plumbing provides expert installation services. We assess your property's needs and local Pomona plumbing codes to recommend the right device type and size. Proper installation is key to lasting protection against contamination.
Irrigation Backflow Preventer Installation in Pomona
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 and theft.

Commercial Backflow Compliance in Pomona
Commercial properties may have several assemblies on domestic water, irrigation, fire lines and equipment. We track test dates, schedule them together and submit all reports. Property managers receive a summary of every device and its status. This keeps you ahead of notices and avoids unexpected shutoffs.
