How to Eliminate Sewer Odor

It’s not always easy to determine where the sewer odor comes from. So, it is a good thing to check all the places where this odor might appear.

As we already mentioned, sewer odor comes inside your house through the plumbing system which means that your toilet, shower drain, or the sink are the source. Finding out the real source will help you to eliminate the sewer odor in no time.

Never the less, we will explain what you should do in each scenario.

Source 1 – Shower Drain

It might be a little bit unusual, but a shower drain is a more common place to have sewer odor than a toilet. Both toilet and shower drains are connected to the main drain pipe which leads down to the sewer. That’s why the smell can come through both of these exits.

Anyhow, if you come across strange sewer smell when you take a shower or when you use shower drain, then you found your source. However, it is always a good idea to check twice and see if you are right.

You can pour a bit of water down the shower drain and wait for the smell to become even stronger. If that’s the case, then we suggest you grab a couple of things.

You will need to use:

Now, follow these instructions and you will get rid of the sewer odor from your shower drain.

1. Remove the cap

First of all, you will need to remove the cap from your shower drain to access it fully. This is quite important since you are going to clean the drain. Over time, many different biofilm build-ups inhabit your drain and they start to smell bad.

That’s why you need to clean it from time to time to prevent this from happening.

2. Prepare the brush

Now, you are going to use the brush for this kind of job. So, take the brush and pour a bit of soap on the bristles. You need to remember that soap is a good thing to use to clean the drain, but not to unclog it.

So, if you have a clogging problem, you should use something stronger.

3. Start cleaning the drain

Take the brush and start cleaning the drain. Since your reach is limited by your hand, we suggest using some kind of extension that can help you to extend your range.

Anyhow, clean the drain as much as you can since the main problem is usually located near the exit.

To Recap

If you see black stuff coming up from your bathtub drain, it is likely clogged drains. To unblock the drain, use a plunger and pour boiling water down the drain until the black material starts to disappear.

The black stuff coming up from your bathtub drain is likely a combination of mold, mildew, and organic debris. This buildup is often caused by standing water in the pipes, which creates a breeding ground for bacteria and fungi. Regular cleaning and proper ventilation can help prevent this issue.

If you’re dealing with plumbing problems, it’s worth exploring the 1975 septic tank design to understand how older systems function. Additionally, if your home has clay pipes under the basement floor, they may be contributing to the issue due to their susceptibility to cracks and root intrusion. For modern solutions, consider the benefits of PEX plumbing in exterior walls.
