As flood waters rise, hydrostatic pressure builds around the home’s foundation. Flood Flaps® patented grill and rubber flaps give way to the pressure of the flood waters, allowing water to enter or exit the enclosed area as necessary. Unlike other flood vents or traditional air vents, our collapsing components allow yard debris and/ or trash (up to 5.75”) to pass through as well. This is extremely important. As flood waters tend to rise rapidly, clogged flood vents or traditional air vents will often clog with debris and trash, thus preventing water from entering the enclosed area and subjecting it to potential collapse. When not subjected to rising water, it takes roughly 15 lbs. of pressure to force the grill out of its secured position. FF Vent Vent Operation Diagram
