Why does my drain smell?

If you ever had asking why does your drain smell, in this article, we are going to explain some of the most common reasons your drain might cause you to plug your nose.

Firstly, some have simple DIY solutions. Others require a professional plumber.

If Something is wrong with the trap, a buildup of organic matter or it can be something else, like mould or even a dead animal in the walls close to the drain, then check this out. It will make your life easier.



The smell could be coming from something as simple as bacteria and gunk buildup.

It could just be bacteria or a clog, or it could be something more serious like a sewer gas leak. When you smell something off coming from your drains, do some sleuth work to root out the source. Clearing your pipes will hopefully get rid of the smell (and slow drains).

We have been providing drain cleaning services for over 80 years to Austin, Tx communities as well as Northern Kentucky and Southern Indiana residents.


A P trap is a plumbing device which prevents odorous gas in plumbing drains and sewers from rising up through a toilet, sink or floor drain

If your drain hasn’t been used recently, fristly you might just need to run the water and refill the P-trap to get rid of the smell. Drain lines have a goose-necked section of pipe installed to block sewer gas from wafting up through the drain.

When the sink is not used, the water in the trap evaporates. This empty drain causes the smell and allows the gas to come into your home. To prevent P-traps from drying out, run a little water in each of your faucets once a month.


Grease is one of the most common reasons of bad-smelling on your drain.

If grease gets stuck in your kitchen sink drain, a rotten egg or mold smell can ensue when it congeals. It is important to never pour grease down your drain.

Throw 2 teaspoons of baking soda into the drain, followed by vinegar and chased with a pot of boiling water. This solution will eat away at the gunk, while the water will wash it away.

If you smell something funky coming form your basement sump pump, you may be directing wastewater into your sump pump instead of through the main sewer drain line.

By reducing the amount of pipes that drain into your sump pump, you can reduce the smell. Make sure you have a proper-fitting cap over the top to help keep smells from wafting into your home. It will also keep objects from falling and collecting inside.
