List of featured suppliers of FLOOR DRAINS Anti-Flood on Building Products Index
Floor drains with anti-flood features are channels or openings in the floor that are designed to efficiently remove water and other liquids to prevent accumulation and flooding. These special types of drains are equipped with a mechanism that helps improve capacity and prevent overflowing during heavy rains or when water pressure is high. The anti-flood feature can be in the form of a check valve or backflow prevention device that shuts off the opening when water flow is too high, preventing water from coming back up through the drain and flooding the area.
