Available for 2-, 3- and 4-inch floor drains, General Pipe Cleaners’ Flood-Guard® 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.
