The Top Reasons Why Foul Odors Are Coming From Your Drains

Posted on: 2 August 2023

If your drains are starting to smell bad there could be several reasons why this is happening. Finding out the exact cause and how to solve it is a must. 

It will help to get your home smell clean and fresh in no time. You will also be able to diagnose whether or not you need to call a plumber to assist you. 

Here are some of the main reasons why drains start smelling.

A Buildup of Bacteria

A smelly drain could be caused by a bacteria buildup. There is a lot that goes down your drains daily and all of this can cause you to smell foul odors. 

The buildup of food, grime, and dirt is enough to cause not only bad smells but blockages in your drains as well. If the smell is unbearable, call a plumber to assist you as soon as you can.

P-Trap Problems

Your drain lines have a section that looks like a gooseneck that is designed to help stop sewer gas from coming up through your drain. If you haven't used your sink for a while, you may notice that once you go back to use it, there will be bad odors coming up through the drain. 

The lack of moisture is the culprit. To prevent this you should always run a little bit of water through your pipes every month even when they're not in use.

Your Garbage Disposal

Your garbage disposal may be broken. When this happens foul odors can come up through the drain in your kitchen. 

If particles start rotting inside your garbage disposal over time you will inevitably start smelling foul odors coming through your drains. 

Grease Buildup

Sometimes grease will get stuck in your kitchen drain. As the grease begins to get old you will smell an odor like rotten eggs coming up from out of your sink. 

This is why you should avoid pouring grease down your drains whenever possible. You may not have to call a plumber immediately to deal with this. 

Try using a few teaspoons of baking soda and throwing it down the drain. You can then add a bit of vinegar and hot water to see if this takes away the odor. If this doesn't work, call a plumber to assist you.

Keeping your drains smelling fresh is critical if you want your home to also smell good. Unfortunately, sometimes problems do arise. If you find that the issue becomes hard to deal with, get a professional to help.

I had no idea how much was really involved in the process, from connecting the sprinkler system to the main plumbing line all the way to burying the individual lines for the sprinkler heads. After researching the entire process and learning as I went, I created this site to give others the benefit of my experience. I hope that the information here helps you be better prepared for what you can expect out of your irrigation system installation, including knowing when it's time to turn to a plumber for help.
