How long does garbage disposals last?

Garbage disposals can work and last efficiently for up to 8 to 15 years typically depending upon its care and maintenance. The longevity or shelf life of disposals depends upon the make and model and the way you use them. Let’s study it thoroughly.

Deep Look at the Lifespan

The lifespan of garbage disposal involves examining its daily usage. Recognizing significant factors that may lead to its premature destruction or demise. A well-driven and well-maintained machine tends to run smoothly for a long time. While a poorly driven and poorly maintained tool or machine will face problems and breakdowns earlier. 

Factors Affecting the Lifespan of Disposal

By keeping in mind the standard durability, certain circumstances can affect the lifespan of garbage disposals. These are as follows,

  • Overloading it with food waste 
  • Not using enough water
  • Disposing of inappropriate items like bones or fibrous foods.
  • Usage frequency, 
  • Maintenance
  • Quality of the disposal
  • Inexpensive or lower-quality garbage disposal

How a user play role in the Lifespan of Garbage Disposal?

Taking care of your disposal plays a crucial role in determining its longevity. Some easy habits to inculcate that can prolong its life are: 

  • Regularly cleaning the system 
  • Not using harsh chemicals in it
  • Avoid putting hard-to-grind objects down your disposal. 

Remember, it is not a magic box. It requires your attention and care to run effectively and efficiently for several years.

The Role of the Make and Model

Like any other machine in your kitchen, the make and model of garbage disposal you choose greatly affects its longevity. Higher-end models equipped with powerful motors and stainless steel grinding components tend to last longer. They are made to bear extensive use without any malfunctioning.

Is there any connection between Disposal Size and Lifespan?

Yes, there is a very deep connection and correlation between the size and lifespan of garbage disposals. The effect of size on the lifespan of garbage disposal depends on factors such as;

  • What amount and type of waste you are disposing?
  • How you are using it?


Larger units are generally built to handle larger amounts of food waste because they have more powerful motors. This extra strength can directly affect the longevity of the unit. A stronger motor means that the disposal can break down waste more easily, reducing strain and potentially increasing lifespan. 

A larger garbage disposal is not always the answer. 

Smaller units, though they may lack the brute force of their larger counterparts compensate with increased efficiency. If they are handling lesser amounts of waste then they are less likely to be damaged. It can also contribute to a longer working life. 

Proper Use and Maintenance

It is important to understand the proper use and maintenance of your garbage disposal. Many people do not think that some waste in the kitchen is not suitable for garbage disposal. Wastes like fats, oils, coffee grounds, and bones can shorten the shelf life of your system. So, to keep it running longer, always remember to treat your garbage disposal right. 

“Think of your garbage disposal as a finely-tuned piece of machinery, not a rubbish bin. It can handle most of your scraps, but some items can be damaging.”

 How to Extend the Life of Your Garbage Disposal?

  • Avoid putting anything that is not biodegradable food in it.
  • Avoid items that the unit cannot effectively grind, such as bones hard fats, and plastic wastes.
