Have you ever wondered what the lifespan of your garbage disposal is?
The short answer is – these kitchen workhorses can last several years, depending on how often you use them and how well they’re cared for.
In the next sections, we’ll go over their expected lifespan, when it’s time for an upgrade, and more. So be sure to keep reading!
The Expected Lifespan of Garbage Disposals
The average garbage disposal will last between 8 to 15 years. However, this number isn’t set in stone; it depends on usage patterns, maintenance habits, and the quality of the unit’s components.
High-end garbage disposal systems, for instance, tend to last longer than their lower-quality counterparts.
Factors That Influence Garbage Disposal Longevity
Regular maintenance is key if you want to prolong your appliance’s lifespan.
For one thing, you want to clean it regularly. How often you use it and the type of food scraps you put in can also influence how long it’ll last. For example, frequent use can lead to quicker wear and tear and eventual replacement.
Similarly, you want to avoid putting certain items into the disposal such as oils, seafood shells, corn husks, and bones.
Hard or fibrous foods like seeds, peach stones, and vegetable stalks can also jam the blades, affecting the efficiency of the disposal.
Recognizing Signs of a Failing Garbage Disposal
Knowing when your garbage disposal is on its last legs is just as important as maintaining it. Recognizing the signs of a failing unit can save you from a potential kitchen disaster and unnecessary repair costs.
Some signs that your garbage disposal may be failing include:
- Loud or unusual noises
- Taking longer than usual to grind food
- Leaking water or other fluids
- Emitting a foul odor
If you notice any of these signs, it may be time to consider replacing your garbage disposal unit.
Other telltale signs include loud humming noises, which may indicate a dead motor, and persistent leaks at the bottom of the entire unit, which generally indicate interior cracks resulting from normal wear and tear, signaling the need for replacement.
The Journey of Food Waste: From Kitchen Sink to Disposal Unit
Modern units utilize a high-torque electric motor that spins a turntable and uses impellers to fling food residue against a grind ring. This shreds and pulverizes food scraps into tiny pieces, which can then be flushed away through the pipes.
However, not all garbage disposals are the same. Some disposal units are powered by water pressure, which use an oscillating piston with blades to effectively chop fibrous debris.
The Role of Garbage Disposal Blades in Efficiency
The spinning blades of a garbage disposal unit are designed to:
- Break down food properly
- Ensure smooth operation
- Prevent clogs and jams
- Maximize the lifespan of the unit
When the blades are not properly maintained, it can impact the unit’s performance and potentially shorten its lifespan.
Interestingly, some garbage disposals have a third stage in the grinding process with an undercutter disc that further chops food waste, optimizing the disposal’s efficiency.
The Impact of Cold Water and Hot Water on Disposal Operation
It’s highly recommended that you run water while using the garbage disposal. But did you know that the temperature of the water can also make a difference?
Cold water is particularly beneficial when running the garbage disposal as it helps solidify fats; it also allows for better chopping, which helps reduce the likelihood of clogs.
Proper Maintenance: Keeping Your Garbage Disposal in Top Shape
Cleaning With ACTIVE Garbage Disposal Cleaner
We highly recommend using ACTIVE Garbage Disposal Cleaner Tablets once a month to prevent odors and gunk buildup.
Step 1: Run Hot Water
Turn on the faucet and run a stream of hot water for one minute.
Step 2: Place the ACTIVE Tablet Into the Drain
Reduce the water to a slow trickle, turn the faucet away from the drain, and place one ACTIVE Garbage Disposal Cleaner tablet inside the disposal.
Step 3: Run the Disposal
Run the garbage disposal until the foam from the cleaner drains. Then rinse the sink with water and turn off the disposal.
Supply:
- ACTIVE Garbage Disposal Cleaner Tablets

Cleaning with Baking Soda and Ice Cubes
In a pinch, you can also clean your garbage disposal with baking soda and ice cubes. Not only will they remove food particles but they will also deodorize the unit.
Supplies:
- Baking soda
- Ice cube
- Water
Step 1:
With the faucet and disposal turned off, place the ice cubes in the drain, followed by one tablespoon of baking soda.
Step 2:
Turn on the garbage disposal and wait until the grinding noises stop.
Step 3:
Turn on the faucet and flush the unit with cold water for 30 seconds while the motor is still running, then turn it off.
Cleaning With Lemon Slices
Citrus fruits such as lemon can also be used to freshen up the garbage disposal.
Supplies:
- Slices of lemon
- Water
Step 1:
Cut a lemon into small wedges.
Step 2:
While running cold water, feed each slice one at a time into the disposal. Continue until the grinding stops.
The lemon’s acidic nature will help break down any grime and slime that’s inside the unit.
You can also use other citric fruits such as oranges.
Cleaning with Salt and Ice
You can also clean your garbage disposal with ice and table salt. Here’s what you want to do.
Supplies:
- Ice cubes
- Rock salt
Step 1:
Pour two cups of ice cubes into the drain, followed by one cup of rock salt.
Step 2:
While running cold water, turn on the garbage disposal. It will crush the ice, allowing it to remove any residue that’s stuck to the blades, while the salt will help eliminate odors.
You can also use table salt or kosher salt.
Cleaning With Baking Soda and White Vinegar
Baking soda and white vinegar is another effective combo if you need to clean your garbage disposal.
Supplies:
- Baking soda
- White vinegar
Step 1:
Pour two cups of baking soda into the disposal, followed by one cup of white vinegar. The two will react will create bubbles and foam.
Step 2:
For the best results, let the mixture sit for one hour. Then, turn the garbage disposal on for at least one minute while running cold water.
Professional Services vs. DIY: When to Call a Plumber
While regular cleaning and maintenance can be done at home, there are times when professional services may be necessary.
For instance, if water is dripping from the garbage disposal, there may be crack in the unit and that would warrant professional plumbing services.
When it comes to replacing garbage disposal units, professional plumbing services may also be the best option.
Upgrading Your Kitchen: Selecting a New Garbage Disposal
There are several factors to consider when choosing a new garbage disposal These include the type of model, including continuous-feed or batch-feed, as well as the type of grinding chamber.

- Basic plumbing and electrical wiring skills
- Tools like a hammer, screwdrivers, and a putty knife
