How long does it take to replace a garbage disposal?

Replacing a garbage disposal takes 1 to 3 hours on average. Installing a new garbage disposal where none existed takes 2 to 4 hours or more, depending on the piping, electrical, or counter modifications needed.

How long does a garbage disposal last?

The average garbage disposal lifespan is 8 to 12 years. Most units have warranties that last 3 to 10 years. A high-quality disposal installed professionally according to manufacturer guidelines has the longest lifespan.

Garbage disposals need this maintenance to last longer:

  • Run cold water while the disposal is grinding.

  • Keep the disposal running for an extra minute after grinding waste.

  • Turn on the garbage disposal at least once daily.

  • Clean it by grinding ice cubes with a cup of rock salt in it every 2 weeks.

  • Flush it out once a month by pouring 0.5 cup baking soda and 1.0 cup of vinegar inside, followed by boiling water.

What are signs the garbage disposal needs to be replaced?

Signs the garbage disposal needs replacing includes:

  • Failure to turn on

  • Abnormal noises

  • Frequent resets

  • Delayed operation

  • Persistent bad smells

  • Water leaks

  • Recurring clogs

  • Blades that don’t grind food waste

  • Disposal leaks under the sink

Who can install or replace a garbage disposal?

A plumber, appliance installer, or handyman installs a garbage disposal. An electrician adds a new outlet, circuits, and wiring extensions for installations where no disposal existed before.

Can you have a garbage disposal with a septic tank?

You can have a garbage disposal with a septic tank, but plumbers advise against it. Extra restrictions apply on what to put in the disposal that won’t disrupt the septic-tank system. Potential issues include sewage clogging, frequent septic-tank inspections, and pump-outs.

Can I replace my garbage disposal myself?

You can replace a garbage disposal yourself when installing the same size unit with existing wiring and pipes in good condition. Hire a professional when changing the model type, moving the unit to a new location, or when electrical or plumbing work is necessary.

What not to put in a garbage disposal

Don’t put these items in a garbage disposal:

  • Coffee grounds

  • Animal bones

  • Hard foods

  • Dry and expandable foods

  • Grease, oils, and fats

  • Nuts, seeds, pits, and shells

  • Large food quantities

  • Non-food items like cleaning chemicals and trash
