A garbage disposal is an important appliance in your kitchen. It helps you get rid of food waste easily and efficiently. But like all appliances, your garbage disposal can break down or wear out over time. How do you know when it’s time to repair or replace your garbage disposal? In this blog post, we’ll discuss the signs that indicate you need to take action.

Your garbage disposal is making strange noises.

One of the most common signs that your garbage disposal needs repair is when it starts making strange noises. If you hear grinding, humming, or rattling sounds, it could be a sign that something is stuck in the disposal or the blades are dull or damaged. In this case, it’s best to call a professional plumber to inspect and fix the issue.

Your garbage disposal is leaking.

If you notice water leaking from your garbage disposal, it could be a sign that there’s a crack or a loose connection in the disposal. Leaks can cause water damage to your cabinets and floors, so it’s important to get them fixed as soon as possible.

Your garbage disposal smells bad.

If your garbage disposal smells bad even after you’ve cleaned it, it could be a sign that there’s a buildup of food waste and debris in the disposal. Over time, these particles can cause bacteria and mold to grow in your disposal, leading to unpleasant odors. Maintaining a regular cleaning schedule can help prevent this issue.

Your garbage disposal isn’t working.

If your garbage disposal won’t turn on or stops working in the middle of use, it could be due to a number of reasons such as a blown fuse, tripped circuit breaker, or a motor that has burned out. In some cases, it may be more cost-effective to replace the whole unit than to repair it.

Your garbage disposal is old.

Garbage disposals typically last around 12 years with proper maintenance. If your disposal is over a decade old and has been acting up lately, it may be time to consider a replacement. Newer models are more energy-efficient, quieter, and have more advanced safety features than older models.


A malfunctioning garbage disposal can cause inconvenience and potential health hazards to your home. Understanding the signs to look out for that indicate you need to repair or replace your garbage disposal is crucial in keeping your kitchen clean and safe. Nonetheless, if you’re unsure of the state of your garbage disposal, contact a professional plumber for inspection and maintenance. By addressing the issues early on, you can avoid costly repairs or replacements in the future.
