As a licensed C-36 contractor with over 30 years of experience, County Backflow delivers certified testing, expert repairs, and professional installations that keep your water clean and your operations compliant.

Whether you manage a multi-unit apartment complex, operate a commercial facility, or own a single-family home, our certified specialists ensure your backflow prevention systems meet all regulatory requirements while protecting public health.

Professional Backflow Testing Services

Annual backflow testing isn't just a regulatory requirement—it's your first line of defense against water contamination. Our certified cross-connection control specialists conduct thorough inspections of backflow prevention assemblies for properties of all sizes, from residential irrigation systems to complex commercial fire service installations.

We handle every aspect of the testing process, including equipment calibration, pressure differential measurements, and complete documentation submission to your local water authority. Our technicians arrive with state-certified testing equipment and deliver same-day certification, ensuring you never face compliance deadlines or water shutoff risks.

For commercial property managers overseeing multiple locations, our multi-device testing programs streamline compliance across your entire portfolio while providing detailed reporting for ownership and regulatory audits.

Expert Backflow Repair and Replacement

When your backflow prevention device fails testing or shows signs of malfunction, immediate professional repair prevents water service interruptions and protects against contamination risks. Our licensed technicians diagnose and resolve issues ranging from worn check valves and damaged seals to complete assembly failures requiring urgent replacement.

Common repair needs include leaking relief valves, pressure drops indicating check valve failure, and visible corrosion affecting device integrity. We maintain extensive parts inventory for all major backflow preventer manufacturers, enabling efficient on-site repairs that minimize downtime for your property.

For assemblies beyond economical repair, we provide expert consultation on replacement options suited to your property's specific requirements and hazard classifications. Our installation warranty and compliance guarantee ensure your new backflow prevention system functions reliably while meeting all applicable codes.

Comprehensive Installation Services

New construction, system upgrades, and changing water district requirements often necessitate professional backflow preventer installation. County Backflow's C-36 contractor license and decades of installation experience across residential, commercial, and industrial applications ensure your new assembly meets precise specifications from day one.

We guide you through device selection based on your property's hazard assessment, water usage patterns, and jurisdiction-specific requirements. From reduced pressure principle devices for high-hazard commercial applications to pressure vacuum breakers for residential irrigation systems, we install the right protection for your unique situation.

Our installation process includes complete site preparation, proper assembly positioning for testing accessibility, and initial certification submission to your water authority. Every installation includes documentation of compliance with state contractor plumbing codes and local backflow prevention ordinances.
