5 Things You Should Never Put in a Garbage Disposal

May 28, 2021 | Blog

When it’s time to clean up your kitchen after cooking, throwing scraps down the garbage disposal might seem like the quick and easy thing to do. However, there are some things that should never be put in it and could result in your garbage disposal not working and needing repairs. Here are some items that you should stick to throwing in the trash can and not down the drain. 


Bones should not be put down the garbage disposal because they will not be able to be broken down. While small pieces might get through, larger bones such as chicken wings will just get stuck. The garbage disposal will try to break the bone down, but it has a greater chance of actually breaking it and clogging the connected plumbing. 


Pasta is something you wouldn’t immediately think of as having the potential to harm your garbage disposal. However, even if they are fully cooked, the pasta will still expand with water. This swelling will lead to clogged drains so it is best to just throw your leftover noodles in the trash. 

Fruit Pits

Similar to bones, fruit pits are too hard for your disposal to handle and break down. Throwing these down there will most likely result in broken or dented blades causing you to need a whole garbage disposal repair. Think with items like these, if you can’t chop it with a knife, your disposal won’t be able to either. 

Grease and Oil

While liquid grease or oil will be able to go through the garbage disposal it will cause major issues in the connected plumbing. The grease will harden over time and clog the pipes which is not something you want to deal with. Instead, drain your oil and grease into a can or jar, seal it and toss it in the trash to dispose of it. 

Coffee grounds

Coffee grounds are a surprising culprit for your garbage disposal not working. As you add more grounds down the drain it will build up and form a sludge similar to what you get in a coffee filter once you make a fresh pot. This will eventually clog the drain so throw those grounds in a compost bin or just in the trash.

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
