How to Stop a Food Disposal From Stopping Up Sewer Lines

Scrape any large bones and large pieces of food into a trash bag or can instead of putting them in your kitchen's food disposal. Wear latex gloves to keep your hands clean.

Scrape any of the following foods into the trash bag or compost container: onion peels, celery, corn husks/cobs, banana peels, artichoke leaves and any other fibrous fruits and vegetables. These types of foods can clog your food disposal and also your home's sewer line.

Turn on your sink's cold water faucet and let it run, then turn on the food disposal. Place small batches of food debris down the disposal as the water is running.

Let the water continue to run for at least two minutes after placing the last batch of debris down the disposal. The cold water helps liquefy the small batches of food.

Pour any grease, including vegetable and olive oil, into a disposable metal or plastic container. Then place the container in the trash bag or can. Pouring the grease into the food disposal or down a drain can clog your home's sewer line.
