Floor Drain Backflow Preventers

Put an end to water damage from backed-up sewers. To install, place a preventer into your floor drain pipe and tighten the screws—the rubber collar will expand for proper fit. When water backs up, the rubber float will rise to seal off the drain. When water recedes, the float will drop for normal drainage.

Square-Head Expansion Plugs

Turn the square head of the plug into the sealing ring to close off pipe openings. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
