NYC Fire Sprinkler FAQ
What is a Siamese connection and why is it required by FDNY?
A Siamese connection is an exterior inlet that allows the Fire Department to pump water into the building's fire sprinkler or standpipe system during a fire. It is strictly required by NYC fire code for commercial and multi-family residential structures.
What is the purpose of an RPZ backflow preventer?
A Reduced Pressure Zone (RPZ) backflow preventer stops contaminated water or chemicals from siphoning back from your building into NYC's public drinking water supply. They are mandatory on commercial main water services and fire sprinkler systems.
