What to Do When Your Kitchen Sink Won’t Drain

A clogged kitchen sink can be frustrating and disruptive, especially when you’re trying to clean up after a meal. While some clogs are minor and can be fixed with simple DIY methods, others may require professional intervention. This troubleshooting guide explains common causes of clogged kitchen sinks, safe DIY solutions, and when to call a plumber for professional drain cleaning.

Common Causes of a Clogged Kitchen Sink

1. Food Waste:
   • Large food particles, coffee grounds, and fibrous materials like celery can accumulate in the pipes, causing blockages.
2. Grease and Oil:
   • Grease solidifies as it cools, creating sticky residue that traps other debris.

3. Soap Scum:
   • Over time, soap can combine with minerals in water to form a hard, clog-inducing residue.

4. Foreign Objects:
   • Small items like utensils, sponges, or scrubbers accidentally falling into the drain can obstruct water flow.

5. Clogged P-Trap:
   • The P-trap under the sink often collects food, grease, and debris, which can restrict water flow.

Safe DIY Solutions for a Clogged Kitchen Sink

1. Use a Plunger

• Create a tight seal around the drain and plunge vigorously to dislodge the clog.
• For best results, block the other sink drain (if you have a double sink) with a wet cloth.

2. Clear the P-Trap

• Place a bucket under the P-trap, unscrew the trap, and remove any trapped debris.
• Reassemble the trap and test the sink for proper drainage.

3. Try Baking Soda and Vinegar

• Pour 1 cup of baking soda followed by 1 cup of vinegar down the drain.
• Let the mixture sit for 15–30 minutes, then flush with hot water to clear the clog.

4. Use a Drain Snake

• Insert a drain snake into the pipe to break up and remove stubborn blockages.
• Be cautious to avoid damaging the pipes.

5. Flush with Boiling Water

• Pour a pot of boiling water down the drain in stages, allowing it to work on grease or soap scum buildup.

When to Call a Plumber

Emergency Drain Cleaning

If the clog persists after trying these DIY methods, it’s time to contact a professional. A plumber can use advanced tools like hydro jetting or a professional-grade drain snake to clear the blockage safely and effectively. Additionally, call a plumber if you notice:

• Slow drainage in multiple sinks, which may indicate a larger plumbing issue.
• Foul odors or gurgling sounds from the drain.
• Water backing up into other fixtures, like the dishwasher or adjacent sinks.

5 Tips to Prevent Kitchen Sink Clogs

1. Dispose of Grease Properly:
   • Pour grease into a disposable container and throw it in the trash instead of down the drain.

2. Use a Drain Strainer:
   • Place a mesh strainer over the drain to catch food particles and debris.

3. Avoid Overloading the Garbage Disposal:
   • Feed food waste into the disposal gradually, and avoid grinding fibrous or starchy materials.

4. Flush Drains Regularly:
   • Pour hot water down the drain weekly to prevent grease and soap buildup.

5. Clean the P-Trap Periodically:
   • Check and clean the P-trap every few months to avoid blockages.
