Rancho Cucamonga Backflow Services

Backflow happens when your water flows in the wrong direction through your pipes, allowing contaminated water to mix with your clean supply. It’s a big problem because even a small pressure change can pull in fertilizer, chemicals, or bacteria into your water supply and put your family’s health at risk.

California and local codes require backflow testing once every year. Annual service keeps your system certified and ensures valves still seal properly under pressure changes.

Backflow usually happens in residential settings when there’s a sudden pressure drop, like a water-main break, heavy outdoor irrigation, or firefighting use nearby. Once that pressure change happens, dirty water from sprinklers or drains can be sucked backward into drinking lines.

Keep an eye out for cloudy water, unusual tastes, or low pressure at multiple fixtures. A failing device could trigger gurgling sounds or short bursts of air from faucets when you turn them on.

Yes! Many older homes in our area were built before backflow rules existed. If your property has sprinklers, a pool, or a hose connection that feeds directly from your main line, you’ll need a certified backflow device installed to stay safe.

A licensed plumber temporarily shuts off your water, checks internal pressure valves, and records performance readings. If everything passes our inspection, you’ll receive a certification for city records. If not, we can help with backflow repairs before retesting.

Combine yearly testing with good plumbing habits, like keeping garden hoses off the ground, installing vacuum breakers on outdoor faucets, and replacing worn devices before they fail. Taking preventive care is the number one way to prevent contamination in your water supply.
