At Flow Go, we specialize in keeping your drains clear and functional for residential homeowners, property management teams, and commercial businesses in the Lowcountry. While our services tackle tough clogs with tools like hydro jetting, prevention is always better than cure. In this blog post, we'll focus on kitchen sink drain maintenance, highlighting what to avoid pouring down the drain, how to prevent clogs, and simple tips to keep your kitchen flowing smoothly.


What Not to Pour Down Your Kitchen Sink

Kitchen sinks often handle a variety of waste, but many common items can lead to stubborn clogs. Based on expert advice from plumbing pros, here's what you should never send down the drain:

  • Fats, Oils, and Grease (FOG): Items like bacon grease, cooking oil, butter, and lard solidify in pipes, creating blockages. Even hot water won't prevent this—grease cools and sticks to pipe walls.

  • Starchy or Fibrous Foods: Pasta, rice, flour, potato peels, and fibrous veggies like celery or corn husks expand in water or get tangled, forming clumps.

  • Coffee Grounds and Eggshells: Coffee grounds act like sediment and build up over time, while eggshells create gritty residue that traps other debris.

  • Meat Scraps and Bones: These don't break down easily and can cause major obstructions.

Instead, scrape plates into the trash or compost, and wipe greasy pans with paper towels before washing.


How to Avoid Clogs in Your Kitchen Sink

Preventing kitchen sink clogs starts with mindful habits and simple tools. Here are effective strategies to keep your drain clear:

  • Use a Sink Strainer: Install a mesh strainer to catch food scraps, grounds, and peels before they enter the pipes. Clean it after every use.

  • Dispose of Grease Properly: Collect cooled grease in a jar or can and throw it in the trash. For larger amounts, recycle at a local facility.

  • Run Hot Water After Use: Flush the drain with hot (not boiling) water after washing dishes to melt away minor residue.

  • Limit Garbage Disposal Use: If you have a disposal, avoid overloading it with fibrous or starchy items. Run cold water while using it to solidify fats for easier passage.

By adopting these practices, you can reduce the risk of clogs and extend the life of your plumbing system.


Regular Maintenance Tips for Kitchen Drains

Routine care keeps minor issues from becoming major problems. Incorporate these tips into your cleaning schedule:

  • Weekly Hot Water Flush: Run hot water for a minute after use to clear residue.

  • Monthly Natural Cleaner: Pour 1/2 cup baking soda down the drain, followed by 1/2 cup vinegar. Let it fizz for 15-30 minutes, then flush with hot water to dissolve grease and buildup.

  • Avoid Chemical Cleaners: Harsh chemicals can damage pipes; opt for natural methods or professional services.

  • Professional Inspections: Schedule annual camera inspections to spot early buildup or issues.

If clogs persist, our hydro jetting service at Flow Go can thoroughly clean your pipes without chemicals.
