Many homeowners throughout NYC’s flood-prone neighborhoods have incurred costly damage from sewage backing up into their property during storms. Besides ruining personal belongings, the wastewater can also pose a health hazard to residents. Select homeowners in qualifying neighborhoods can now receive a free backwater valve installation through a federally-funded program. By installing a valve, homeowners can protect family, finances and property. Participants in the program also receive an elevation certificate and expert analysis that could help lower flood insurance rates.
