4 Common Garbage Disposal Mistakes and How to Fix Them

If you own a garbage disposal, you know how useful it is for quick kitchen cleanup. But even small mistakes lead to jams, leaks, and nasty odours. Before calling plumbers Pennant Hills, check if you are making one of these four common mistakes.
Here is how to avoid damage and fix issues before they get worse.

Putting the wrong items down the disposal

Garbage disposals are not designed for all food scraps. Hard, sticky, or fibrous foods damage the blades or clog the pipes.
Avoid putting these in your disposal:
• Bones
• Coffee grounds
• Eggshells
• Banana peels
• Rice and pasta
Instead, dispose of these items in the rubbish bin or compost. If clogged, try plunging or resetting the disposal.

Not running enough water

Running the disposal without enough water leads to build-up in the pipes. Food waste sticks to the drain and hardens over time.
How to fix:
• Always run cold water for 10 seconds before using the disposal
• Keep the water flowing while the disposal is running
• Let the water run for 15 seconds after switching off
This flushes particles out of the system and keeps pipes clear.

Using hot water during operation

Hot water softens grease and fat. These stick to the blades and pipes, forming blockages as the water cools.
Use cold water while grinding food waste. Hot water is fine for cleaning after all waste has cleared.

Forgetting to clean the disposal

Odours and rust form when you do not clean regularly. Old food particles and bacteria build up under the blades.
Quick cleaning method:
• Pour half a cup of baking soda into the unit
• Add a cup of white vinegar
• Let it fizz for a few minutes
• Rinse with cold water and drop in a few ice cubes and lemon peels while running the disposal
This deodorises and sharpens the blades slightly.
When to reset or call a plumber
• The disposal makes a humming noise but does not grind
• Water leaks under the sink
• You smell gas or burning odors
• The reset button does not restore power
Most units have a reset button underneath. If problems persist, turn off power and call a licensed plumber.
Ways to extend the lifespan of your garbage disposal
• Use it weekly to prevent rust
• Avoid overloading with food scraps
• Use cold water every time
• Clean monthly with natural products
Simple habits keep your disposal running for years.
