Items You Should Never Put Down Your Kitchen Sink

The best preventative way to ensure that your drains stay healthy is knowing what items should not be thrown down your drain, even if you have a garbage disposal. There are many common household items that you can forget about when it comes to putting down your drain system to avoid any drain clogs. A kitchen drain clog can really be annoying, from being clogged or just draining slowly. If you need a fast and reliable plumber in the middle of Tennessee area you should contact our team. We have compiled a short list of items to avoid below.

Pasta & Rice

Do not let pasta and rice make its way down your drains. They are a problem because they enter your drain and they expand over time. As you run more water down your plumbing system, These materials keep swelling and cause huge clogs in your drain system.


Eggshells are another good item to never put down your drain. You might think that your kitchen sink’s garbage disposal can handle anything but when they are ground up, they turn into a rough grit like sand substance that can dull your blades over time. Make sure that eggshells end up in your trashcan rather than your drain.

Coffee Grounds

Coffee grounds are the main culprit of drain clogs. Coffee grounds are not water soluble, so they combine with the preexisting Fat, Oil and Grease (FOG) in your system and cause drain blockages. Make sure that when you take out those spent coffee grounds that they end up in your trash. Also make sure this is true when you clean your coffee maker.

Fat, Oil & Grease

Fat, oil, and grease are the top three culprits of drain clogs, especially in the south. You might love to make that morning bacon and sausage but please do not pour that grease down your drain. Plumbers commonly referred to this as “FOG.” These items are such a problem because you think they might go down your drain as a liquid, but they will cool and settle in your pipes as a sludge like solid. It is easy to avoid putting FOG down your drain, allow these warm liquids to cool and become solids. Once they are solids, dispose of these items in the trash can.

Drain Cleaning Products

Many people are surprised by this item but it is important to call a professional plumber if you have a drain clog do not try to solve this problem with an over the counter drain cleaner. The chemicals used in these cleaning products are incredibly corrosive and hard on your pipes. It is more than likely that you will cause more problems through time rather than permanently fixing your drain clogs.

Produce Stickers

It is common that when you purchase fruit and vegetables that you will find stickers on them. These tiny stickers seem arbitrary , but the adhesive used to have them stick on to the produce actually causes problems within your plumbing system.

Also, make sure that any pits in your fruit are put into the trash can. Your garbage disposal and drain system are not capable of handling these hard, round pits.
