Do you need to run water while running the garbage disposal?

Yes, you absolutely need to run water while running the garbage disposal, and this is critical for proper operation, preventing clogs, and extending the life of the unit. You should run a strong stream of cold water, not hot water, before, during, and after operating the disposal. Start the cold water first, then turn on the disposal, then feed food waste gradually. Keep water running while grinding. The water serves several purposes. It flushes food particles through the grinding chamber, down the drain pipe, and into the sewer system, preventing waste from accumulating and causing blockages in the chamber or in your pipes. Cold water is recommended because it keeps fats and grease solid, allowing the disposal to chop them into small particles that can be flushed away, whereas hot water melts grease that can later solidify further down the drain and cause clogs. Water also cools the motor and lubricates the grinding action. After you finish grinding and turn off the disposal, continue running cold water for 15 to 30 seconds to flush any remaining particles completely out of the drain line. Never operate the disposal dry, as this causes overheating, excessive wear on the grinding components, and can damage the motor.
