THE FLOOD-GUARD FLOOD PROTECTION SYSTEM is available for 2", 3" and 4" floor drains. It operates like a check valve to seal off water back-up cause by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. The unit's float rises to seal off the drain opening until water recedes. The easy-to-install unit is available in a stand-pipe model for handling higher pressure.
