What Can & Can't Go Down the Kitchen Drain?

Sinking Feeling: What can (and Canโ€™t) Go Down the Drain?

The pipes in your house are like veins in your bodyโ€”itโ€™s critical that they donโ€™t become blocked. The best way to prevent nasty clogs? Recognize the items that do not belong down the drain, and dispose of that waste somewhere else.

Common Culprits

  • Fats, oils, and grease: Fatty foods such as butter and grease congeal and block pipes.  Theyโ€™re bad for sewage systems too. Putting fats, oils, and grease down the drain can even result in sewage backing up into you or your neighborโ€™s homes. Scrape as much of these foods as you can off of dishes and into the trash.
  • Coffee grounds: Coffee grounds donโ€™t fully dissolve in water, and they can mix with oil or grease to form nasty clogs. Youโ€™re better off throwing grounds into the trash, or even better, composting them.
  • Eggshells: A popular urban myth suggests that eggshells sharpen disposal bladesโ€”they donโ€™t. Eggshell membrane can wrap around and jam the shredder ring, and the ground up shells can stick to pipes and clog. Send eggshells to the trash instead.
  • Retentive foods: Pasta, rice, potatoes and beans absorb water and turn into a mushy paste, clogging the trap. Your pipes will thank you if you put these foods in the trash.
  • Garbage: Produce stickers are a prime problem for drain disposal. Garbage usually doesnโ€™t dissolve in water, so it contributes to pipe blockages. Small pieces of garbage, such as stickers, can also cause problems when they hit water treatment plants.
  • Paint: Paint, turpentine, nail polish, and other chemicals should never go down any drain. Theyโ€™ll do serious damage to your plumbing system. Dispose of these chemicals at a local hazardous-waste facility.
  • Pharmaceuticals: These wonโ€™t plug your drain, but they still shouldnโ€™t be disposed of this way, because itโ€™s irresponsible to introduce over-the-counter or prescriptions drugs to the local water supply. Find a local medication disposal program to properly get rid of any old medicines you have lying around.

Other Non-Flushables

  • Feminine hygiene products
  • Paper towels
  • Motor oil
  • Antifreeze
  • Flammable materials
  • Corrosive substances

These materials should not go into any of your drains, but for your kitchen sink specifically, remember: if itโ€™s not food, it doesnโ€™t drain. And donโ€™t forget the food-specific guidelines weโ€™ve already outlined. Being mindful of what you put into your plumbing system can go a long way in maintaining its healthโ€”and yours, too.
