Garbage Disposals: The Do's, Don'ts, and When to Call a Pro
As a plumber, I've seen my fair share of garbage disposal disasters. These kitchen workhorses can be incredibly convenient, but they're often misunderstood and misused. Today, let's grind through the facts about garbage disposals – what they can handle, what they can't, and how to keep them running smoothly.
What Is a Garbage Disposal?
First, let's clear up a common misconception: a garbage disposal is not a trash can. It's a device installed under your sink that shreds food waste into tiny pieces, allowing it to pass through your plumbing system.
The Do's of Garbage Disposal Use
Do run cold water while the disposal is grinding. This helps solidify any grease or oils so they can be chopped up instead of coating the pipes.
Do grind small amounts of citrus peels (lemon, lime, orange). They help clean the disposal and leave a fresh scent.
Do grind small bones (like chicken or fish bones). They actually help clean the grind ring.
Do run your disposal regularly. This prevents rust and corrosion.
The Don'ts of Garbage Disposal Use
Don't put fibrous or stringy foods down the disposal. Items like celery, corn husks, or onion skins can tangle and jam the motor.
Don't grind coffee grounds. They create a sludgy mess that can clog your pipes.
Don't put potato peels in the disposal. The starches can create a thick paste.
Don't grind large amounts of eggshells. While a few are fine, too many can create granular waste that sticks to pipes.
Don't put non-food items down your disposal. It's not designed for anything other than biodegradable food waste.
Maintaining Your Garbage Disposal
Clean it regularly: Grind ice cubes and a bit of rock salt to scrub the sides of the grinding chamber.
Freshen it up: Grind lemon or lime peels to eliminate odors.
Keep it sharp: Occasionally grinding small bones or ice will help keep the blades sharp.
Troubleshooting Common Issues
Disposal won't turn on: Check if it's plugged in and if the reset button at the bottom of the unit needs to be pushed.
Humming but not grinding: Turn it off immediately. An object might be jamming it.
Leaking: This could be from several places - the sink flange, the hose connecting to the dishwasher, or the discharge pipe.
When to Call a Pro
While garbage disposals are generally low-maintenance, there are times when you need a professional:
If your disposal is leaking and you can't locate the source.
If it's making unusual noises that don't resolve after checking for obstructions.
If it frequently trips the reset button or your circuit breaker.
If there are persistent bad odors even after cleaning.
Remember, attempting to repair a garbage disposal yourself can be dangerous. The blades are sharp, and there's a risk of electrical shock. When in doubt, call a licensed plumber.
The Bottom Line
A well-maintained garbage disposal can last 10-12 years. By following these guidelines, you can keep your disposal running smoothly and avoid costly repairs or replacements.
And remember, the best way to use your garbage disposal is sparingly. While it's a convenient appliance, the most environmentally friendly option is always to compost when possible and limit the amount of food waste you produce.
