What Not to Put Down Your Garbage Disposal in Highwood Homes

Seasonal PrepUpdated June 29, 2026

Garbage disposals do a lot of work in Highwood kitchens, but we see plenty of preventable problems caused by putting the wrong things down the drain. With many homes in town built decades ago, including plenty with older drain lines and clay tile sewer pipes, even one clogged disposal can start a bigger headache. Taking a little care with what you send through your disposal will protect both your unit and your home's plumbing, especially with summer gatherings and holiday cooking when kitchen use goes up.

Why Older Highwood Homes Face Unique Disposal Challenges

Many houses here were built in the early to mid-20th century. Original galvanized or cast iron drain lines don't clear as easily as new PVC. Clay tile main lines, common in our area, also clog fast if fibrous or starchy waste gets stuck. The moderate water hardness in Highwood helps limit scale, but it doesn't stop food debris from building up inside pipes. Frequent freeze-thaw cycles in winter can shift pipes just enough for debris to catch and create a clog. That means garbage disposal mistakes can lead straight to a call for drain cleaning or even a sewer line check if roots or heavy buildup are in play.

Items You Should Never Put Down Your Garbage Disposal

  • Grease, fats, and oils, Even if they go down hot, they cool and solidify in pipes, sticking to walls and trapping debris. This is one of the top causes of slow drains and backups.
  • Fibrous vegetables, Celery, asparagus, corn husks, artichokes, and onion skins can wrap around disposal blades and jam the mechanism. They don't break down easily in water.
  • Starchy foods, Potato peels, pasta, and rice swell with water and form a paste that can gum up both the disposal and drainpipe, especially in older drains or clay tile sewers.
  • Eggshells, The thin membrane inside an eggshell can wind around the shredder ring. The gritty pieces also settle in traps and pipes, contributing to clogs.
  • Bones and hard pits, Chicken bones, peach pits, and similar items don't grind down and will dull or jam disposal blades. Small bones can bounce inside and loosen parts.
  • Coffee grounds, These seem harmless but clump into a dense, sandy sludge in traps and pipes, especially when clay soil in the area slows drainage outside.
  • Non-food items, Twist ties, produce stickers, sponge pieces, plastic, and glass can break the disposal and damage the motor or pipes downstream.

How to Prep Your Disposal and Drains for Highwood's Seasonal Changes

Kitchen drains face extra use during summer cookouts and holidays. In cold months, pipes contract and shift, making pre-existing buildup more likely to cause clogs. Prepping for each season helps avoid an emergency call.

  • Run cold water before, during, and after using the disposal. This keeps fats solid so the blades can chop them up and flush them away.
  • Only grind small amounts of food waste at a time. Overloading leads to jams and inefficient grinding.
  • Give the disposal a quick clean with ice cubes and a bit of dish soap. This knocks debris off the blades and helps prevent odors.
  • If you notice slow drains, gurgling sounds, or frequent resets on the disposal unit, schedule garbage disposal maintenance before it turns into a full blockage.
  • If your home still has galvanized pipes or clay tile main lines, consider periodic pipe inspections or even updating sections prone to clogs.

Warning Signs You've Got a Disposal or Drain Problem

Catching problems early can help avoid major kitchen disruptions. Watch for:

  • Disposal that hums but doesn't spin
  • Slow draining water in sink basins
  • Persistent drain odors despite cleaning
  • Water backing up into other fixtures, like the dishwasher or another sink
  • Need to keep pressing the reset button more often than usual

All of these usually signal a jam, partial clog, or worn-out disposal. If you're seeing backups in a basement laundry sink or floor drain, the problem might be further down the drain line or sewer. In that case, it's smart to call for professional leak detection or sewer line cleaning to get to the root of the issue.

Keeping Your Disposal and Drains Healthy in Highwood

We see kitchen drain problems spike after big family meals or neighborhood events. Using your disposal correctly makes a difference, especially with older plumbing. Remember, avoid stuffing in anything that won't break down easily. Scrape starchy, greasy, or fibrous scraps into the compost or trash can instead.

Frequently Asked Questions

We recommend keeping bones and fruit pits out of your disposal. Even small, hard items can damage the grinding components and lead to jams or costly repairs in the long run.

Odors are usually caused by food debris stuck under the splash guard or along the disposal walls. Try cleaning with ice cubes and a small amount of dish soap, and use a brush under the splash guard. If the smell persists, there may be buildup in the pipes or P-trap.

Check if the reset button has popped out on the bottom of the unit. Also, make sure the circuit breaker hasn't tripped. If it still won't start after these checks, you might have a jam or an electrical issue that needs a professional look.

Yes, eggshells tend to stick to the inside of your pipes and can get caught in the disposal's grinding ring. Over time, this can lead to slow drains or even a full blockage.
