Basement Flood Protection - New York

A backwater valve can help prevent sewage from flowing from the pipes back into your home during heavy rain. New York City building code requires valves for many new buildings and major renovations. The work must be done by a licensed plumber.

After installation, inspect the valve periodically to make sure it works when you need it.


NOTE: To check if a plumber or electrician holds a valid license, visit NYC.gov/buildings or call 311
(TTY: 212-504-4115). For any of these improvements, get quotes from multiple contractors.  Some contacts are provided below:
