Protect Your Water Supply—Certified Backflow Testing and Device Installation.

Protecting your drinking water from contamination is a critical responsibility for property owners. Backflow occurs when water flows in the reverse direction through your plumbing system, potentially allowing contaminated water to enter the clean water supply. At Fito Plumbers, we provide comprehensive backflow testing and prevention services for commercial, industrial, and residential properties throughout Alameda County and Contra Costa County. Our certified technicians ensure your backflow prevention devices are functioning properly and that your property remains in compliance with local water quality regulations.

What Is Backflow and Why Is It Dangerous?

Backflow is the unwanted reversal of water flow in a plumbing system, which can occur due to back pressure or back siphonage. When backflow happens, contaminated water from irrigation systems, fire sprinklers, industrial processes, or other sources can flow backward into the potable water supply, posing serious health risks. Contaminants that can enter the water supply through backflow include chemicals, fertilizers, bacteria, and other hazardous substances. Backflow prevention devices are designed to stop this reverse flow and protect public health.
