Running a garbage disposal without a strong, continuous stream of cold water can cause severe operational damage. Without water to lubricate and flush the grinding chamber, food waste turns into a thick, sticky paste that overheats the motor, clogs the impellers, and gums up your drainage pipes. Furthermore, running the unit dry causes friction that rapidly wears out the rubber shaft seals, leading to premature motor housing leaks. Verification: Always turn on a steady stream of cold water for at least 15 seconds before, during, and after operating your garbage disposal.
