Backflow Prevention Installation and Testing in Waltham, MA

Waltham homeowners often have 1900s-1930s two-families in the core — and these homes commonly have galvanized supply and undersized 3/4″ main gas lines. That changes how a backflow prevention install gets scoped. We walk the system before we quote and tell you exactly what’s involved.

Waltham installs we handle: We install and annually test backflow prevention assemblies — RPZ devices, double-check valves, pressure vacuum breakers, and atmospheric vacuum breakers — required by Massachusetts plumbing code on irrigation systems, boiler feeds, fire suppression, and commercial connections.
