What You Should Never Put in Your Garbage Disposal

November 3, 2020 | Blog

Thanksgiving is right around the corner. Luckily for you, this means that your tummy will soon be filled with plenty of delicious food. Unfortunately, the same cannot be said about your garbage disposal, which does not benefit from being jammed with food. Thanksgiving is actually the busiest day of the year for plumbers – and many of the issues come from broken garbage disposals.

Foods to Avoid Putting in Your Garbage Disposal

Here are the top foods to avoid tossing in your disposal this thanksgiving to avoid garbage disposal repair fees and stress:


The disposal blades will just spin the bones around without breaking them down. If the blades do manage to break down the bones, they will still have a hard time traveling down the drain.

Stringy Vegetables

Vegetables like celery and asparagus tangle around the disposal blades, which can damage them.

Coffee Grounds

Grounds may appear to slide down the sink easily, but tossing them in the disposal results is a mushy mess that builds up in your drain.


The shell’s membrane lining can stick to the sides of the disposal and wrap around the blades.

Fruit Pits

Fruit seeds are too hard to break down, which can damage the blades.


Grease and oil can clog your pipes, especially when hot water is poured in (since it solidifies the fat).


Whether cooked or not, pasta expands with water. Tossing pasta in the disposal will fill the disposal trap due to swelling.

Potato Peels

Starchy veggies cause a soggy mess in your disposal which leads to a buildup.

How to Protect Your Disposal

This is such a popular topic that even The Washington Post covered it. Two of the most common mistakes people make that decrease the lifespan of a garbage disposal are not cleaning it correctly and using hot water while the disposal is turned on. To expand the lifespan of your disposal:

  • Use cold water instead of hot water
  • Clean the disposal correctly: do not use bleach or harsh drain cleaners
  • Use the correct operating sequence: rinse, grind and then rinse again
  • Only toss in food items
  • Do not pour grease or fat into the disposal, which can solidify in the pipes

What to Do When Your Garbage Disposal Breaks Down

If you find that your garbage disposal is clogging frequently, releasing unusual odors or making strange noises, it might be time for a garbage disposal replacement.

Contact Gotelli Plumbing if you need garbage disposal services or if you need a garbage disposal installation.

Quick Response Time

The response from Gotelli Plumbing was excellent. The next time Tom arrived right on time and the quality of his work was outstanding. When he finished he walked me through everything he had done and I could not have been more pleased with the results. I’m so thankful to have such professionals available when need and on such short notice.

Excellent Service

Tom provided excellent service. He is obviously experienced- and quickly solved the problem. Our gas had to be shut off, so we were without our stove to cook, furnace to heat and hot water. Our home is happy again!
