    What Should Never Go Down Your Kitchen Drain?

    Your kitchen sink handles a great deal of daily use, but it is not designed to dispose of every type of food or household waste. Putting the wrong substances down the drain can create buildup, odors, slow drainage, and serious blockages.

    Fats, Oils, and Grease

    Cooking grease may enter the drain as a liquid, but it can cool and solidify inside the piping. Over time, it combines with food particles and other debris to restrict the drain.

    Allow grease to cool and place it in an appropriate disposable container instead.

    Coffee Grounds

    Coffee grounds do not dissolve in water. They can collect inside traps and drain lines, especially when combined with grease.

    Eggshells and Fibrous Food

    Eggshell fragments, celery, onion skins, corn husks, and other fibrous materials can contribute to clogs and may wrap around garbage-disposal components.

    Rice and Pasta

    Rice and pasta absorb water and expand. Large amounts can create thick, sticky obstructions inside the drain.

    Flour and Dough

    Flour can combine with water to create a paste that adheres to the inside of pipes. Scrape flour, batter, and dough into the trash before rinsing dishes.

    Harsh Chemicals

    Chemical drain cleaners can damage certain plumbing materials and create dangerous conditions for anyone who later opens the drain. They may also provide only temporary relief without removing the underlying blockage.

    Use the Garbage Disposal Carefully

    A garbage disposal is intended for small amounts of suitable food waste. Run cold water while using it, feed waste gradually, and allow the water to continue briefly after the disposal is turned off.

    Recurring kitchen clogs may indicate buildup farther inside the drain system. Avellino Plumbing provides professional drain repair and plumbing service throughout Spring Hill, Columbia, Franklin, Brentwood, Nashville, and surrounding areas.
