Can I put small bones or seafood shells in my garbage disposal?

We don't recommend putting any bones, seafood shells, or fruit pits in your disposal. These items are too hard and can break or jam the shredder ring. Over time, they also contribute to clogs in older cast iron or galvanized pipes.

What should I do if my kitchen sink is draining slowly after using the disposal?

A slow-draining sink often means there's a clog in your P-trap or further down the line. Sometimes, it's due to a buildup of food waste, grease, or fibrous material. Try running cold water and the disposal for a minute, but if the problem continues, it's best to get a professional drain cleaning.

How can I safely clean and maintain my disposal?

Periodically running cold water with a handful of ice cubes helps clear debris from the disposal blades. Adding a slice of lemon can help neutralize odors. Avoid using harsh chemical cleaners, as these can damage internal seals and nearby pipe joints.

Why does my disposal smell bad even after I clean it?

Persistent odors are usually a sign of food waste stuck inside the disposal or deeper in the drain line. If cleaning with ice and citrus doesn't help, professional attention may be needed to clear buildup in the pipes or disposal chamber.

What to Avoid in Your Garbage Disposal

MaintenanceUpdated July 7, 2026

Many homes in Westchester, especially those built in the 1920s and 1930s, have older drain lines and plumbing systems that don't play well with certain kitchen habits. A garbage disposal can be a handy tool, but using it wrong is a shortcut to drain clogs, worn-out parts, and even sewer backups. We see frequent disposal and drain issues across the western suburbs, and most of the time, they start with the same preventable mistakes.

Why Older Westchester Homes Need Extra Care

A lot of the local housing stock has original or older galvanized and cast iron pipes. These materials are more vulnerable to buildup and corrosion compared to newer PVC or copper. Add in the clay-rich local soil and flat terrain, and slow drains become a bigger problem, especially if you're sending the wrong things down your disposal. Even with municipal Lake Michigan water, scale buildup from moderate hardness can coat pipes and trap debris.

Common Disposal Mistakes That Lead to Trouble

It's easy to assume a garbage disposal can handle anything. In reality, the motor and blades are designed for small bits of soft food, not for breaking down tough or fibrous materials. Some items may seem harmless but stick to pipes or gum up the internal mechanisms. Here are items you should never send through your disposal:

Grease, fat, and oil: These coat the disposal's blades and the inside of your drain lines. Over time, they harden and create stubborn blockages.
Fibrous vegetables: Celery, corn husks, asparagus, artichoke leaves, and onion skins can get tangled around the blades and jam the motor.
Potato peels and starchy foods: These break down into a paste that sticks to the sides of the disposal and pipes, causing clogs.
Eggshells: The membrane can wrap around the shredder ring, and the shell fragments combine with oils to form clogs.
Rice and pasta: These expand with water and can form a sticky mass that blocks your P-trap or main line.
Coffee grounds: Grounds settle in the trap and act like sand, building up until water can't flow.
Fruit pits, bones, or shellfish shells: Hard materials can damage disposal blades and burn out the motor.

We advise scraping plates into the trash or compost before rinsing dishes, especially if you live in an older home or have had drain cleaning issues in the past.

Signs Your Disposal or Drain Needs Attention

Even with the best care, disposals and kitchen drains wear down over time. Watch for these warning signs in your Westchester home:

Water backs up into the sink or drains slowly.
Grinding or humming noises during disposal use (can mean a jam or seized blade).
Persistent bad odors, especially after cleaning the unit.
Leaks under the sink, often at the disposal flange or drain connections.
The reset button trips often, signaling an overload.

If you notice any of these, our garbage disposal services can handle repairs or replacement safely, preventing bigger headaches down the line.

Tips for Smooth Disposal Operation

We want Westchester homeowners to get the most out of their disposals without risking their plumbing. Here's what works for keeping everything in good shape:

Run cold water before, during, and after using the disposal. This keeps fats solid so they flush out rather than congeal in pipes.
Feed waste in gradually rather than dumping large amounts at once.
Rinse with a mix of ice cubes and a slice of citrus now and then to clean blades and reduce odor, but avoid commercial drain cleaners that can damage seals.
If you're noticing recurring clogs or have old galvanized pipes, consider an annual sewer line check or upgrade to newer plumbing materials. We handle pipe repair and repiping as needed for aging systems.

How Your Disposal Affects the Rest of Your Plumbing

Everything you grind up in the kitchen ends up in your main drains and sewer. In Westchester, where many homes have original plumbing, even a small kitchen clog can become a bigger issue, leading to backups or leaks further down the line. If you're dealing with slow sinks throughout the house, or if you've had repeated drainage issues, it's wise to have professional leak detection and repair to check for hidden pipe problems.

When to Call for Professional Help

Routine maintenance goes a long way, but if your disposal stops working, trips the breaker, or starts to leak, you're better off calling a licensed plumber. Trying to fix a jam with your hand is dangerous and risks damaging the unit or your fingers. In older Westchester kitchens, underlying issues like rusted pipes, worn-out supply lines, or even main line obstructions are common. We're equipped to clear stubborn blockages, replace aging disposals, and inspect for plumbing trouble beyond just the appliance.
