Customer Questions and Answers for Garbage Disposal Drain Stopper by Whirlpool

This is a rubber or plastic stopper that fits into the opening of a garbage disposal unit in the kitchen sink. It serves as a splash guard during operation and can be used to plug the drain when filling the sink with water. Replace it if it has become cracked, warped, or no longer fits snugly in the disposal opening, causing water to drain or debris to splash out.
