Can I put small bits of eggshell down the disposal if I run a lot of water?

We don't recommend putting eggshells down the disposal at all, even with plenty of water. The membrane layers can wrap around disposal bearings, and the gritty shells add to buildup in older pipes. Toss them in the compost or trash instead.

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

Persistent odors usually mean food debris or grease is stuck on the disposal blades or further down the drain line. Try running ice cubes and dish soap through the disposal. If smells linger, you might have deeper buildup in aging pipes, and professional drain cleaning may be needed.

Is it safe to pour hot grease down the drain if I follow with cold water?

No. Hot grease will cool and solidify as it moves through pipes, especially in the cold months. This can quickly clog galvanized or cast iron drain lines common in River Grove homes. Always dispose of grease in a container in the trash.

What should I do if my disposal jams or won't turn on?

First, turn off the disposal and check for obvious obstructions using tongs (never your hand). Try pressing the reset button. If it still won't run, the problem may be more serious, and forcing it could damage your drain or disposal. Contact a licensed plumber for safe repairs.

What Not to Put in Your Garbage Disposal

Seasonal PrepUpdated July 18, 2026

Every winter and holiday season, our team sees an uptick in garbage disposal calls around River Grove. Most are preventable. If you're dealing with older plumbing, common in local homes built from the 1950s to the 1970s, you can't afford a clog or damaged disposal when the ground is frozen and pipes are already stressed. The clay soil and high water table in our area add another layer of risk for backups and basement headaches. A jammed or leaking garbage disposal can quickly turn into a bigger drain or sewer problem if the wrong things go down your sink.

Why Garbage Disposals in River Grove Need Special Care

Many houses here have galvanized steel or even cast iron drain lines that are decades old. These pipes corrode and are less forgiving than modern PVC. If you feed your disposal the wrong scraps, you're not just risking motor burnout, you could send tough material or grease right into lines vulnerable to clogs and tree root intrusion. In older neighborhoods with clay-tile sewers, it doesn't take much to create a blockage that goes beyond the kitchen and affects your whole home. That's why we stress prevention.

The Top Items to Keep Away From Your Disposal

Grease, oils, and fats: Hot or cold, pouring these down your disposal will coat pipes and catch debris, leading to slow drains or total blockage. Even if it seems to go down smoothly now, it can solidify deeper in your line.
Fibrous vegetables: Celery, corn husks, onion skins, and artichokes tangle around the impellers and may lock up the motor.
Eggshells: The membrane layers and shell fragments can gum up moving parts and collect with other debris downstream.
Starchy foods: Potato peels and pasta expand and form a gluey mess inside pipes, especially with River Grove's moderately hard water.
Coffee grounds: These clump together into heavy sludge, perfect for clogging aging drain lines.
Rice and beans: Like pasta, these keep swelling with water and won't break down in the disposal.
Bones, pits, or shells: Even small bones or fruit pits can snap disposal blades or jam the unit completely.
Non-food scraps: Glass, plastic, metal, twist ties, and cleaning pads can destroy your disposal instantly and cause hazardous clogs in cast iron or galvanized pipe.

How River Grove's Plumbing Challenges Make Disposals Vulnerable

The clay-heavy soil and flat terrain in Cook County mean that when a disposal or drain line clogs, there's a bigger risk of water backing up into your basement or kitchen, especially if sump pumps aren't working properly. Many River Grove homes connect to original clay-tile sewer lines, which are prone to root intrusion. Clogs that start at the kitchen sink often get stuck at joints or bends in these older pipes. This isn't just a minor annoyance. If the disposal sends a surge of debris into a weakened line, you could end up needing sewer line services fast.

Warning Signs Your Disposal or Drains Are In Trouble

Persistent odors even after cleaning the disposal
Water pooling in the sink or draining slowly
A loud humming noise or the motor struggling to spin
Reset button trips frequently or the unit shuts off mid-use
Water backing up in other fixtures (like the dishwasher or basement floor drain)

If you notice these issues, you may need professional drain cleaning. Don't try to grind through stubborn blockages, especially if your pipes are older or you suspect any root growth in your sewer line.

Practical Tips for Healthy Disposals and Drains

Always run cold water before, during, and after using the disposal. Cold water solidifies any stray grease, helping the blades chop food more cleanly for the trip through old pipes.
Feed food scraps slowly, don't dump a whole plate at once. Smaller loads reduce strain and help prevent jams, especially with worn impellers.
Use a drain screen to catch food debris you don't want in your disposal at all. This is especially useful if you tend to peel veggies or wash plates directly over the sink.
Every week, flush your disposal with a mix of ice cubes and a bit of dish soap. The ice helps knock debris off the blades, while the soap cuts residue that can stick to drain line walls.
If you suspect your pipes are older galvanized or cast iron, schedule regular inspections to catch corrosion and buildup before they become real problems. Our pipe repair & repiping crew can advise what's safest for your setup.

Seasonal Considerations and Local Know-How

Winter in River Grove puts added stress on plumbing. Frozen ground outside means any kitchen backup is twice as tough to fix. Our winters can freeze exterior vents or slow old drain lines. Summer thunderstorms occasionally knock out sump pumps or overload main sewers, so kitchen waste winds up where it shouldn't. It's smart to get your garbage disposal serviced before big gatherings or seasonal cooking sprees. If you're planning a kitchen update, ask about faucet and fixture installation at the same time. That's an efficient way to spot lurking drain or supply line issues.
