When do I need a backflow preventer?

Are you in need of a larger water service for your existing building? Planning a new building? Or did you receive a violation from the DEP for not having a backflow preventer installed on your existing water service? The backflow preventer approval is always a big pain for developers; it’s notoriously a very slow approval, affecting the whole project.

What does a backflow preventer do?

Having a backflow preventer installed is now a retroactive mandatory item on all buildings in New York City. A backflow preventer protects the city’s water supply by not allowing any water that enters your building to flow back into the city’s water mains under the street.

How do I apply for a backflow prevention design with the city?

To comply, a backflow preventer design and application must be submitted by a professional engineering firm to DEP. This entails a detailed survey of the site or drawings where the backflow preventer will be located.
