This 3" Flood-Guard Float Model prevents basement flooding. It operates like a check valve to seal off water back-up caused by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. Then the Flood-Guard float rises to seal off the drain opening until the water recedes. Once in place, it can prevent property damage and a very messy clean-up job.
