The answer to 'how long does garbage disposal last' is that a typical garbage disposal has an average lifespan of 8-15 years with proper care and maintenance. Garbage disposals are designed to be durable and long-lasting appliances, but their longevity can vary depending on factors like usage, maintenance, and the quality of the unit.
Higher-quality disposals made with stainless steel components tend to last longer than budget models with plastic parts. Proper care, such as regularly cleaning the disposal, avoiding putting hard objects down it, and using it in moderation, can also extend its lifespan. When a disposal starts making strange noises, leaking, or losing power, it may be time to consider replacing it to avoid potential plumbing issues.
