What is Backflow Prevention?
Backflow occurs when contaminated water reverses direction and flows back into the clean water supply. This can happen due to changes in water pressure—such as a water main break or heavy fire hydrant use—and can introduce chemicals, bacteria, and other hazardous substances into drinking water.
Backflow prevention devices are mechanical assemblies installed on your building’s water lines to stop this reverse flow. They act as one-way gates, ensuring water only moves in the intended direction.
NYC requires backflow prevention devices on a wide range of properties, including:
- Commercial buildings— offices, retail spaces, restaurants, and hotels
- Multi-family residential buildings— apartment complexes and condominiums with shared water systems
- Industrial facilities— manufacturing plants, warehouses, and processing centers
If your property has a connection to the NYC water supply and poses any cross-connection risk, you almost certainly need a backflow prevention assembly—and it must be tested annually.
