FEMA-compliant automatic flood vent engineered to open and close with water pressure — no electricity required. Equalizes hydrostatic pressure during flooding to protect foundation walls from structural cracking. One vent provides 200 sq ft of flood coverage credit under NFIP regulations, reducing flood insurance premiums in participating communities. Installs in standard 16x8 CMU or poured concrete foundation openings.
