Fixing a jammed garbage disposal with hex wrench.
Why Your Kitchen Sink Smells Like Rotten Eggs: 5 Easy Garbage Disposal Fixes (Save $200 on Plumber Fees)
Does your kitchen smell like a dumpster even after you’ve taken out the trash? If that "rotten egg" or "mystery organic" odor is wafting from your sink, the culprit is almost certainly your garbage
In the US and Canada, the garbage disposal is the workhorse of the kitchen, but it's also a breeding ground for bacteria and trapped food waste. Before you panic and call a plumber (who will charge you $150–$300 just for a visit), follow this DIY guide to diagnose, fix, and deodorize your disposal like a pro
1. The "Red Button" Secret (The Reset)
Many homeowners don't realize their disposal has a built-in circuit breaker. If your unit isn't making any sound at all, it might just be tripped.
- The Fix: Reach under the sink and look for a small red reset button at the bottom of the unit. If it’s popped out, push it back in
- Pro Tip: If it trips again immediately, there is an electrical short or a major jam.
2. The "Humming" Sound: How to Unjam It Manually
If you hear a low humming sound but the blades aren't spinning, the motor is jammed. DO NOT keep the power on, or you’ll burn out the motor.
- The Fix: 1. Unplug the unit for safety.
- 2. Find the hex wrench (Allen wrench) that came with the unit (usually 1/4 inch).
- 3. Insert it into the hole at the very bottom center of the disposal.
- 4. Turn it back and forth until the blades move freely
3. The Deep Clean: The Ice and Lemon Hack
Over time, a "sludge" of grease and food particles builds up on the underside of the impellers. This is what causes that foul smell.
- The DIY Fix: 1. Fill the disposal with two cups of ice cubes and half a cup of rock salt.
- 2. Turn on the cold water and run the disposal. The ice "scours" the blades without dulling them.
- 3. Finish by tossing in some lemon or orange peels. The citrus oils provide a natural, fresh scent that lasts for days.
4. Checking for Leaks: The "Vibration" Factor
Disposals vibrate intensely, which can loosen the mounting ring or the "dishwasher connector" pipe over time.
- Where to look : Dry the unit completely, then wrap a paper towel around the top flange. Run the water. If the towel gets wet, your plumber's putty has likely failed and needs a 10-minute reseal.
5. What NEVER to Put Down Your Disposal
To stay ahead of the competition and keep your sink running perfectly, avoid these "Disposal Killers":
- Coffee Grounds: They turn into a "sediment" that clogs the P-trap.
- Eggshells: The thin membrane can wrap around the blades.
- Pasta/Rice: They expand in water and create a sticky paste.
- Grease/Oil: This is the #1 cause of the "rotten egg" smell as it rots inside the pipes.
