5 Common Kitchen Sink Problems & Easy DIY Fixes

Your kitchen sink works hard every day—washing dishes, rinsing veggies, and handling all sorts of messes. But when something goes wrong, it can quickly turn into a headache. The good news? Many common sink issues can be fixed without calling a plumber. Here are five frequent problems and simple solutions to get your sink back in shape.
1. Clogged Drain
A slow or blocked drain is usually caused by grease, food scraps, or soap buildup. Instead of reaching for harsh chemicals, try this natural fix:
- Pour boiling water down the drain.
- Follow with ½ cup baking soda and ½ cup vinegar.
- Let it fizz for 10-15 minutes, then flush with more hot water.
This eco-friendly method clears most clogs and keeps your pipes clean.
2. Leaky Faucet
A dripping tap wastes water and drives you crazy. Often, the issue is a worn-out washer or cartridge. Here’s how to fix it:
- Turn off the water supply.
- Disassemble the faucet (use a wrench if needed).
- Replace the damaged part—most hardware stores carry affordable replacements.
A quick fix now saves water and prevents bigger leaks later.
3. Stinky Drain
If your sink smells like rotten food, bacteria and debris are likely trapped in the pipes. Try this:
- Pour baking soda and vinegar down the drain.
- Let it sit, then rinse with hot water.
- For extra freshness, toss in citrus peels.
This trick eliminates odors naturally.
4. Low Water Pressure
Weak water flow? The aerator (the small screen on your faucet) might be clogged with mineral deposits.
- Unscrew the aerator and soak it in vinegar for 30 minutes.
- Scrub gently, rinse, and reattach.
Your water pressure should improve instantly.
5. Leaky Pipes
Puddles under the sink often mean loose fittings or cracked pipes.
- Turn off the water and inspect the pipes.
- Tighten connections or apply plumbing tape.
- If a pipe is damaged, replace it.
Catching leaks early prevents mold and water damage.
Final Tip: Regular maintenance (like avoiding grease down the drain) keeps these problems from coming back. Try these fixes before calling a pro—you might save time and money!
