Backflow Prevention & Testing Services

Backflow occurs when contaminated water flows backward into your clean water supply, potentially introducing harmful substances into your drinking water. Backflow prevention devices are essential safeguards that protect your family's health and are often required by local codes. Addario's Plumbing Services provides complete backflow prevention services.

We install backflow prevention assemblies for residential and commercial properties, perform annual testing required by many municipalities, and repair or replace faulty devices. Our certified technicians ensure your backflow prevention system meets all code requirements.

Many towns in Massachusetts require annual backflow device testing. We provide testing services and submit the required documentation to your water department, making compliance simple and convenient.
