Backflow Prevention Testing Services
Backflow prevention devices protect a building’s water supply from contamination by stopping water from flowing in the wrong direction. New York City requires these devices to be tested annually, with the results filed with the Department of Environmental Protection.
Our team tests, repairs, and installs backflow prevention devices, including double check valve assemblies (DCVA), reduced pressure zone (RPZ) valves, and pressure vacuum breakers (PVB), for buildings across Manhattan, filing the required GEN215B documentation with the DEP.
A backflow device that fails its annual test needs to be repaired or replaced before it can pass. We handle the full process, from testing through filing, so the building stays compliant.
Which Buildings Need Backflow Prevention Testing?
Buildings with certain water system connections, including many with fire sprinkler systems, boilers with chemical treatment, or connections that pose a contamination risk to the public water supply, are required to have a backflow prevention device tested annually. The Department of Environmental Protection typically notifies building owners when their annual test is due.
Backflow Prevention Testing in Manhattan: Local Considerations
Much of the Lower East Side, particularly along corridors like Orchard Street and Essex Street, mixes ground-floor retail and commercial space with residential units above, and that kind of mixed-use connection is exactly the situation that often requires a backflow prevention device.
Older co-op buildings in this neighborhood, including Hillman Housing and East River Housing, may have backflow devices that have been in place for years, making annual testing especially important for catching wear before it causes a failed test.
Because Manhattan’s water infrastructure serves a dense mix of building types packed closely together, from co-ops to newer developments like Essex Crossing, the Department of Environmental Protection treats backflow compliance as a citywide priority regardless of a building’s age.
