While it’s safe to run hot water from the sink through the garbage disposal, we recommend that you use cold water when you are operating the disposal. Use a strong flow of cold water and keep the disposal running at least 30 seconds after grinding has stopped so that all food particles are flushed through the drain line. Cold water will also solidify any fatty and greasy waste so it is chopped up and flushed down the drain (hot water will make fat and grease liquefy and coagulate).
