NYC’s Backflow Preventer & Plumbing Specialists

Backflow Prevention of New York is a licensed NYC plumbing company serving all five boroughs. We built our name on backflow preventer testing and compliance. Then, property managers who trusted us with that work asked us to handle the rest of their building systems too. Today we cover gas, boilers, drains, and emergencies, with the same approach that earned the backflow work: we only recommend what you need, we track your deadlines, and we show up on time.
