Garbage Disposal Mistakes That Lead to Clogs (And How to Avoid Them This Summer)

Garbage disposals are one of the most convenient features in your kitchen—until they stop working.

During the late spring and summer months, disposal issues become much more common across homes in Fairfield County and New Haven County. More cooking, more guests, and heavier kitchen use can quickly lead to clogs, jams, and unpleasant odors.

The good news? Most garbage disposal problems are preventable.

1. Putting the Wrong Foods Down the Disposal

Not everything belongs in your garbage disposal—even if it seems harmless.

Avoid putting these items down your disposal:

• Grease, fats, and cooking oil

• Coffee grounds

• Eggshells

• Pasta, rice, and bread

• Fibrous vegetables (celery, corn husks, onion skins)

These materials can either harden inside your pipes or expand with water, leading to stubborn clogs over time.

2. Not Using Enough Water

Your garbage disposal relies on water to move food waste through your plumbing system.

If you run the disposal without enough water, debris can stick to the sides of your pipes and build up.

Best practice: Run cold water before, during, and for at least 10–15 seconds after using your disposal.

3. Pouring Grease Down the Drain

This is one of the most common causes of kitchen drain clogs.

Grease may go down as a liquid, but it quickly cools and solidifies inside your pipes—especially in older homes throughout Fairfield County and surrounding areas.

Over time, this buildup restricts water flow and can lead to complete blockages.

4. Overloading the Disposal

Trying to push too much food waste through your disposal at once can overwhelm the system.

This can lead to:

• Jams

• Motor strain

• Incomplete grinding

Instead, feed waste gradually while the disposal is running to keep everything moving properly.

5. Ignoring Strange Noises or Smells

If your garbage disposal starts making unusual noises or producing persistent odors, it’s usually a sign of buildup or a developing issue.

Common warning signs include:

• Grinding noises that sound different than usual

• A humming sound with no blade movement

• Foul odors that don’t go away with rinsing

Addressing these early can help prevent a full system failure.

6. Not Cleaning Your Disposal Properly

Even when used correctly, garbage disposals can develop residue over time.

To keep your disposal fresh:

• Run cold water regularly

• Use a mild dish soap flush

• Avoid harsh chemical cleaners that can damage your pipes

Routine cleaning helps prevent odors and keeps your system running efficiently.

When to Call a Professional

Some garbage disposal issues can’t be fixed with simple maintenance.

You may need professional service if:

• Your disposal won’t turn on

• It repeatedly clogs or backs up

• You notice leaks under the sink

• Your kitchen drain is slow even after running the disposal

  
  

These issues may indicate a deeper plumbing problem that needs to be addressed before it worsens.

Prevent Summer Plumbing Problems Before They Start

With increased kitchen use during the warmer months, small disposal issues can quickly turn into larger drain problems.

Taking a few simple precautions now can help you avoid unexpected repairs and keep your plumbing system running smoothly all summer long.
