Backflow Testing & Prevention

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.

Types of Backflow Prevention Devices

Different applications require different types of backflow prevention devices. The most common types include:

• Reduced Pressure Zone (RPZ) Assemblies: Provide the highest level of protection and are required for high-hazard applications.
• Double Check Valve Assemblies (DCVA): Used for moderate-hazard applications where the risk of contamination is lower.
• Pressure Vacuum Breakers (PVB): Commonly used for irrigation systems to prevent back siphonage.
• Atmospheric Vacuum Breakers (AVB): Simple devices used for individual fixtures and hose connections.

Annual Backflow Testing Requirements

Most municipalities require annual testing of backflow prevention devices to ensure they are functioning correctly. Property owners are responsible for scheduling these tests and providing certification to their local water district. During a backflow test, our certified technicians inspect the device, perform a series of pressure tests, and verify that all components are working as designed. If the device fails the test, we provide immediate repair or replacement services to bring it back into compliance.

Who Needs Backflow Prevention Devices?

Backflow prevention devices are required for many types of properties and applications, including:

• Commercial Buildings: Restaurants, medical facilities, car washes, and other businesses with potential cross-connections.
• Industrial Facilities: Manufacturing plants, chemical processing facilities, and other industrial operations.
• Irrigation Systems: Properties with underground sprinkler systems that connect to the potable water supply.
• Fire Sprinkler Systems: Buildings with fire suppression systems that use the municipal water supply.
• Multi-Unit Residential Properties: Apartment buildings and condominiums with shared water systems.

Backflow Device Installation and Repair

In addition to testing, we provide complete backflow prevention device installation and repair services. If your property requires a new backflow device, our team will assess your needs, recommend the appropriate type of device, and install it in compliance with all local codes. When repairs are needed, we carry a full inventory of parts and can quickly restore your device to proper working condition, ensuring you maintain compliance and protect your water supply.

Stay Compliant and Avoid Penalties

Failure to test your backflow prevention device annually or to repair a failed device can result in fines, water service interruption, and potential liability if contamination occurs. We make compliance easy by providing timely testing, prompt repairs, and all necessary documentation for submission to your local water district. Many of our commercial clients rely on us to manage their backflow testing schedules and ensure they never miss a required test.
