The answer to 'how long does garbage disposal last' is that a typical garbage disposal has an average lifespan of 8-12 years with proper use and maintenance. Garbage disposals are durable appliances, but they do wear down over time due to the constant grinding action and exposure to food debris and water. Proper care, such as regular cleaning and avoiding putting certain items down the disposal, can help extend its lifespan.
It's important to note that the actual lifespan can vary depending on factors like the disposal's quality, how frequently it's used, and whether any issues arise over time. Homeowners should keep an eye out for signs of wear, such as slower grinding or strange noises, and be prepared to replace the disposal if it starts malfunctioning.
