Fats from holiday cooking could lead to home sewer backups

LOUISVILLE, Ky. — Louisville MSD is advising everyone to can your grease! The holidays are full of many delicious, fatty, oily and greasy dishes that are great to eat but can cause problems with plumbing. 

What You Need To Know

  •  Louisville MSD says that oils, fats and grease can cause sewer backups in to your homes
  •  Garbage disposals and grease-cutting detergent still allow these kitchen wastes to pass into your plumbing
  •  Never pour them down your sink, drain or toilet
  • MSD recommends pouring grease into a can, freezing it and then tossing it in the garbage 

When greasy scraps of food wash into the plumbing system through your sink or garbage disposal, they can stick to the pipes. Using your grease-cutting detergent or garbage disposal does not keep oils, grease and fats out of the plumbing system. Proper disposal of these kitchen wastes is critical to prevent sewer backups. 

Louisville MSD suggests the following to help prevent a sewer backup into your home: 

Can the grease!

  • Never pour fats, oils and grease down a sink, drain, or toilet. Pour used grease into an empty, heat-safe container, such as a soup can, and store it in the freezer. Toss the can into the garbage after the grease becomes solid.
  • Scrape your food waste into the trash. Wipe all pots, pans, dishes, and cooking utensils with a paper towel to soak up grease before washing them. 
  • Catch the scraps in your sink with a basket or strainer instead of using the garbage disposal, and throw them away in the trash can. 
  • Do not pour deep-fryer oil on the ground or in a storm drain, as it can flow to a waterway or clog the storm pipe.
  • Recycle your deep-fryer oil by taking it to Louisville Metro’s grease drop-off locations.
