There is nothing more disgusting than dealing with a nasty odour in your kitchen sink’s drain. Not only will a stinky drain leave the whole household with unpleasant smells, but it can also make every family member sick. Imagine eating in your kitchen with that nasty smell emanating from somewhere that will make you puke. If you are experiencing this issue, you must take prompt actions to get rid of this odour as soon as possible. 

In this article, we will share practical tips to handle a foul odour in your kitchen sink drain:

1. Use some household remedies

You can use a handful of household products to address a drain odour. As soon as you smell something wrong from your kitchen sink, consider using the following solutions:


  • Baking soda and vinegar: Start by pouring one cup of baking soda into the drain and applying the same amount of vinegar after. Be sure to let them sit for about ten minutes before you pour boiling water down the drain.


  • Hot water and dish soap: Put a stopper into the sink and pour hot water halfway. Once done, be sure to put some dish soap in. Finally, pull the plug and turn on the disposal as the sink drains.


  • Citrus peels, ice, and salt: Put some ice cubes and sprinkle a handful of salt down the drain. Once done, run the disposal for about ten seconds and put a couple of citrus peels in the disposal. Finally, grind them up for a deodorizer while running the water.

2. Adjust some plumbing parts

There are also some plumbing parts you’ll have to adjust to address the kitchen sink drain odour, depending on the specific circumstance. Here’s what you can do:


  • Blockage: Check a small cup at the lowest point of the curve of your kitchen drain. If there’s a blockage, be sure to clear it and run water for a few minutes.


  • P-trap: This curvy part of the pipe under the sink is designed to block the gases from going the wrong way. If it is dry or blocked, it can cause the sewage smell to come from the sink. As such, be sure to stop the evaporation from causing the smell.


  • Clogged vent: The long, narrow vertical vent sticking out of your roof connects your main sewer line to the outside air. If it is clogged, the sewer gas won’t be released and can get into your home space. For this reason, be sure to clean it up.


  • Leak: It’s important to inspect for potential leaks in your pipe under the kitchen drain. All it takes is to remove the connections on either side of the P-trap and clean them out.

3. Call a plumbing expert
