Backflow Preventer Testing in Sharon, MA

Massachusetts DEP requires annual testing of all backflow prevention assemblies. Our certified testers inspect, test, and submit required documentation to your local water authority on your behalf.

When a backflow preventer fails its annual test, we perform all necessary repairs — replacing internal components, check valves, and seals to restore full function and compliance.

We install all types of backflow prevention assemblies including Reduced Pressure Zone (RPZ), Double Check Valve (DCVA), and Pressure Vacuum Breaker (PVB) devices for new and existing systems.

Commercial properties, irrigation systems, and fire suppression systems are required by law to maintain certified backflow prevention. We handle testing, repair, and documentation for property managers and business owners.

Lawn irrigation systems are a common source of backflow contamination. We test and certify backflow preventers on residential and commercial irrigation systems to protect the municipal water supply.

We provide complete test reports and submit required documentation directly to your local water authority, ensuring your records are always up to date and compliant.
