    Floor Drain Trap Seals

    Image of Product. Front orientation. Floor Drain Trap Seals.
    Stop sewer gases from escaping through your floor drain if the P-trap dries out. Similar to a check valve, they allow liquid to drain but won’t let gases back up. They’re especially useful in infrequently used drains. To install, remove the strainer from your drain and place these seals in the opening. They have fins that grip the inside of the drain and a top ring to keep them in place. After putting the strainer back, pour water through the drain to fill the P-trap.

    Floor Drain Check Valves

    Image of Product. Front orientation. Drain Check Valves.
    Put an end to water damage from backed-up sewers. To install, place a valve 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.
