Check the Garbage Disposal Before Holiday Cooking

· 3 stories · By Chris

Holiday cooking puts a lot more food down the kitchen sink than a normal week. A disposal that already hums, leaks or smells bad will not suddenly get better with turkey scraps and potato peels. A quick check before the big cook days saves a clogged sink in the middle of dinner.

Turn on a steady stream of cold water, then flip the disposal on for 10 to 15 seconds with nothing in it. It should sound smooth and even. A loud grind, a hard rattle, a hum with no grinding, or water that backs up into the sink means stop. Do not keep flipping the switch hoping it will catch. Reset buttons under the unit are for a jam after power is off — not a habit to mash every holiday.

Look under the sink too. Drips at the disposal body, the dishwasher hose connection or the drain pipes are a problem now, not once guests are there. A wet cabinet floor under the disposal is a stop sign.

Home tip

Keep a dedicated tongs or pliers near the sink. Power off at the wall switch (and unplug if it has a cord) before you pull anything out of the chamber. Never reach in with bare fingers.

Grease, fat and cooking oil belong in a can, then the trash — not the disposal. Same for coffee grounds, large bones, fruit pits, eggshells, pasta, rice and fibrous scraps like celery, corn husks and onion skins. Those materials jam the grind ring, pack the trap or coat the pipes so the next load sticks.

Holiday leftovers that are soft food scraps can go through with plenty of cold water running before, during and after. Small batches beat one huge dump. If the disposal is already weak, skip it and use the trash or compost where allowed.

Home tip

Cool grease in a disposable container, then toss it. Hot grease poured "just this once" is how holiday clogs start.

When the disposal needs a pro, not another reset

A disposal that trips the reset over and over, leaks at the body, smells like burned plastic, or leaves the sink slow even after a careful cold-water grind is past homeowner tricks. Chemical drain openers are a bad idea here — they can damage parts and create a hazard if you later open the pipes.

If the unit will not start, the sink will not drain, or water is under the cabinet, leave it alone and book a diagnostic. Holiday week is the wrong time to force a stuck motor.

Home tip

Disposal humming, leaking or backing up before the big meal? Call me at (470) 999-7395. A $79 diagnostic is how I find out whether it is a jam, a failed unit or a drain line problem.
