Why Does My Sink Smell? How to Get Rid of Smelly Drains

Clearing an odd or unpleasant aroma from your plumbing means you can enjoy your kitchen and other spaces around your sink again. Address the root cause of drain and pipe odors with this guide.

Reasons Why Your Sink Drain Smells Bad

Before resolving your smelly sink drain, figure out what’s causing the odor. Common reasons for drain odors include:

Bacteria and Microbe Growth

Microbes like bacteria thrive in water and nutrient-packed spaces like drains and pipes. As they develop and grow, they can release smelly gases.

Waste Residue

Food scraps and other waste caught in your sink drain or garbage disposal can accumulate, cause a significant blockage and start to smell.

Water Leaks

Leaks around your sink pipe or other piping components can cause mold. Soaked wooden cabinets and other elements can develop mildew and give off a musty odor.

Clogged Sewer Vent

Sewer vents release gases from pipes and encourage proper drainage. When they clog, they can slow drainage and trap sewer gases, leading to pungent scents.

Damaged Sewer Line

A compromised sewer line with damaged piping or other components can also result in stinky gases escaping into your indoor spaces.

Plumbing Mistakes

If you’ve tried to make patch DIY repairs to your sink or noticed an odd aroma after a recent plumbing service, there may be an issue with your plumbing. Mistakes like forgetting to install a component can affect the workings of your whole sink, leading to leaks and other issues.

Sulfate-Rich Water

Too much sulfate in your water supply can give your sink a strong rotten egg aroma. Sulfates can also lead to drainage issues, clogging your sink drain.

How to Get Rid of a Stinky Sink Drain Odor

These home fixes can help you get rid of that smell:

• Flush with boiling water two to three times. Add dish soap to a sink full of water and bubble it up for one flushing round.
• Pour one cup of baking soda and one cup of vinegar down the drain and flush with boiling water after 10 minutes.
• Switch off your garbage disposal and pour ice cubes and two spoons of coarse salt down the drain. Switch the disposal back on before adding lemon peels to help remove odor.
• Buy a drain cleaner and follow the instructions. Opt for natural, enzyme-based solutions, as they can be more effective than chemicals for tearing down organic materials in your drain.
• Especially if this is an ongoing issue, call a professional to diagnose the root of the problem. Contact our drain specialists at Dash Drains.
