For light residential use, a 1/3 to 1/2 horsepower (HP) motor is usually sufficient. However, for larger families or heavier use, we recommend a 3/4 to 1 HP model. Commercial kitchens require specialized units starting at 1 HP to handle continuous, high-volume waste.

With proper usage and maintenance, a high-quality residential garbage disposal typically lasts between 10 and 15 years. Commercial units undergo more stress but are built with heavier-duty components, offering similar lifespans when regularly serviced.

Always run cold water before, during, and a few seconds after grinding. Avoid putting fibrous foods (like celery or corn husks), expandable items (pasta, rice), and excessive grease or oil down the drain. Cutting larger scraps into smaller pieces also helps maintain motor health.

While the disposal can easily grind them, coffee grounds and eggshells can accumulate in your plumbing pipes over time, acting like a thick paste that causes stubborn clogs. We recommend composting these items instead of grinding them.
