A water main break requires immediate action to minimize property damage and restore water service. Step 1: Shut off your main water valve if possible. Step 2: Call 311 to report the break to NYC DEP. Step 3: Call Sewer & Water Pros at (917) 447-7377 for emergency repair. Step 4: Document the damage with photos for insurance purposes. Step 5: Avoid contact with the water, which may be contaminated. Step 6: Notify your insurance company. Our emergency team responds 24/7 and can obtain emergency permits from DEP to begin repairs immediately. Do not attempt to repair a water main break yourself — this requires licensed professionals and city permits.
