Just like every plumbing fixture, garbage disposals have a lifespan too. On average, a good garbage disposal can last around 8 to 15 years, depending on several factors that we will discuss in the blog.
So, if your garbage disposal is starting to show signs of wear and tear, there is a chance it has lived its life.
Factors Affecting Garbage Disposal Lifespan
These factors can affect how long a garbage disposal unit lasts:
1. Quality of the Unit
Better-quality garbage disposals, especially heavy-duty ones, usually last longer than cheaper models. It might cost you more upfront, but it saves a lot of money on repairs and replacements. So, make sure you invest wisely.
2. How Often You Use It
Another factor that affects how long a garbage disposal lasts is the usage frequency. The more you use your disposal, the faster it wears out. A unit used several times a day won’t last as long as one used only occasionally.
3. What You Put in It
Never put grease, bones, fibrous foods (like celery), or really hard items in the disposal. (Small, soft bones like fish bones occasionally are okay in high-powered disposals, but not recommended in basic models.) These can damage the blades and motor, impacting the longevity of your garbage disposal unit. Avoiding these items can help extend the life of your unit.
4. Maintenance and Care
Keep your disposal clean and in good shape. Run cold water while it’s on, this helps grind food better and protects the blades from damage. These simple maintenance tips make sure the garbage disposal lasts you years.
Signs You Need a Replacement
If you suspect the following signs, it might be time to replace your garbage disposal unit:
- Unusual noises
- Water leaks under the sink
- Foul odors despite cleaning
- Recurrent clogs
If you notice these issues, it’s a good idea to call a professional plumber to check it out. They can confirm if a repair is enough or if a new unit is needed.
How To Extend Your Garbage Disposal’s Life?
Here are some tips on how to extend your garbage disposal’s life:
- Run cold water while using the disposal to help grind food better and protect the blades
- Avoid putting the wrong things down the disposal, like grease, bones, or fibrous foods
- Clean it regularly to prevent buildup and odors
- Get professional inspections if needed to catch problems early
- Make sure it is installed professionally with no leaks or other issues
When is Replacing Worth It?
No one wants a malfunctioning garbage disposal. Not only it is unhygienic but also hampers your daily chores. Here is when replacement is worth it:
- If your disposal is older than 10–12 years and keeps having problems
- If it has frequent jams, leaks, or bad odors that don’t fix
- If repairs are costing nearly as much as a new unit
- If you want a quieter, more powerful, or energy-efficient model
Final Word
Typically, a garbage disposal unit can last from 8 to 15 years depending on the unit quality, usage frequency, items you drain and maintenance. If you suspect frequent clogs, unusual noises, foul odors, or water leaks under the sink – it might be time to replace the unit.
