How Long Do Garbage Disposals Last?

There is no single best way to answer this question. There are different factors that will come into play, such as the brand of the product you are using.

The latter will have an impact on its quality and longevity. The extent of use, as well as care and maintenance, will also influence the number of years the disposal can last.

Make your Garbage Disposal Last Longer

It is also crucial to be mindful on what gets in the garbage disposal. You have to avoid pouring grease and oil, which will cause the system to clog. Rice and pasta are also best to avoid because they can expand and can clog the pipe. Fruit pits and fibrous vegetables can also cause serious problems.

Using a plumbing device or snake is also a good idea, at least once every two years. This allows you to get rid of the food debris stuck on the disposal that can compromise its performance.

Be sure to religiously follow the instructions from the manufacturer when it comes to its care and maintenance. The failure to do this will not only shorten the lifespan of the unit but can also make the warranty void.

Pay Attention to These Problems

So, is it about time to replace your old garbage disposal? An easy way to answer this question is to pay attention to the problems that are being shown by the unit.

One of the most serious is the failure to grind food scraps. If you notice that the waste remains unprocessed after putting it in, the blades or motor are most probably already weak because of its many years of use.

In some cases, the garbage disposal will make a noise that is louder than the usual. It is also possible that it will make a noticeable vibration.
If there is a foul odor that won’t go away even after days, this is also a sign that you already need a replacement.

You should also pay attention to water leaks. It could be because there are problems with the pipe or the disposal is already too old and you need to invest in a new one.


As discussed in this article, a typical garbage disposal will last for 12 years, although, extent of use, care and maintenance, and its brand name, among others, will have an impact on its lifespan.
