List of featured suppliers of FLOOR DRAINS Trapped on Building Products Index
Floor drains that have a "trap" built into them are known as trapped floor drains. This trap is designed to prevent odors, gases, and insects from entering the building through the drain. The trap holds a small amount of water, which creates a barrier that prevents these unwanted elements from passing through the drain and into the building. Trapped floor drains are commonly used in commercial and industrial buildings, but they can also be found in residential settings, particularly in basements and garages.
