My garbage disposal is humming but not spinning — what should I do?

A humming disposal means the motor is getting power but the grinding plate is jammed. Turn the disposal off immediately to avoid burning out the motor. Use the hex wrench (Allen key) that came with the unit to manually turn the flywheel from the bottom of the unit. If you can't free it or don't have the key, call a plumber.

What should I never put in a garbage disposal?

Avoid putting grease or cooking oil, fibrous foods (celery, corn husks, artichokes), starchy foods (pasta, rice, potato peels in large quantities), bones, coffee grounds in bulk, egg shells in bulk, and non-food items down the disposal. These can jam the blades, coat the drain, or cause clogs further down the line.

Why is my garbage disposal leaking from the bottom?

A leak from the bottom of the disposal usually means the internal seal has failed. This is not repairable — the unit needs to be replaced. Leaks from the top (sink flange) or side (dishwasher connection or discharge pipe) can often be fixed by tightening connections or replacing gaskets.

How long does a garbage disposal typically last?

Most disposals last 8-15 years depending on usage and maintenance. Signs it's time for replacement include frequent jams, persistent odors despite cleaning, leaks from the body, and the unit taking longer to grind food. Upgrading to a higher-horsepower unit can improve performance and longevity.

What horsepower garbage disposal do I need?

A 1/3 HP disposal handles light use for one or two people. A 1/2 HP is adequate for most households. A 3/4 HP handles heavier use and tougher scraps. A 1 HP model is best for large families or frequent cooking. We recommend at least 1/2 HP for most homes to avoid frequent jams.

Can a plumber install a garbage disposal, or do I need an electrician?

A plumber handles the plumbing connections and can replace a disposal on an existing electrical hookup. If you're installing a disposal for the first time and need a new electrical outlet or switch under the sink, an electrician may be needed for the wiring. We coordinate with electricians when electrical work is required.
