Often used to prevent spills from going down your drain, these plugs resist oil and most chemicals. They are nonabsorbent, washable, and reusable. An eyebolt at the top makes these plugs easy to insert and remove.

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.
