What is the average life expectancy of a garbage disposal?
Thursday, March 5, 2020
How long does a garbage disposal last?
You can expect a disposal to last about 10 to 14 years, with an average of 12 years. But the lifespan will be shortened if you put things down the disposal that it is not equipped to handle, such as grease, egg shells, celery, or bones.
Here’s a graph comparing garbage disposal life expectancy with other home appliances.
Also, see our blog posts Why is garbage disposal not allowed at a combination waste and vent (CW&V) under a sink? and Why do septic tank contractors want you to get rid of your kitchen disposal?
Go to our blog post What is the average lifespan of the parts of a house? for rating of other house components. To understand the basis, potential use, and limitations of lifespan ratings, see How accurate are the average life expectancy ratings of home components? Are they actually useful?
