A smelly kitchen sink can make your whole kitchen feel unclean—even if everything else is spotless. If you’ve tried running hot water or pouring vinegar down the drain with no luck, it might be time to look deeper.
At Doug the Plumber, we’ve helped countless Comox Valley homeowners eliminate kitchen sink odours at the source. Whether it’s a blocked drain, a dry trap, or a hidden buildup of food waste, we’ll find the issue and fix it—fast.
What Causes Kitchen Sink Odours?
Unpleasant smells in your kitchen sink can come from several common plumbing problems:
-
Clogged or dirty drains: Grease, food particles, and soap scum can stick to the inside of your pipes and start to rot.
-
Dry P-trap: If the sink isn’t used often (like in a basement or rental unit), the water in the trap can evaporate, allowing sewer gases to rise up.
-
Blocked or broken vent pipe: Plumbing vents let sewer gases escape through the roof—if blocked, they can push odours back into your kitchen.
-
Garbage disposal issues: Built-up grime under the splash guard or on the blades can smell over time.
DIY Fixes to Try First
Before calling a plumber, you can try:
-
Running hot water and dish soap to clear grease
-
Pouring baking soda and vinegar followed by hot water
-
Checking if the P-trap is dry and pouring water into it
If the smell returns or never goes away, the issue is likely more complex.
