How to Get Rid of Sewer Gas Smell in Basement

If you think you have a sewage gas smell in your basement, it’s important to know what you’re dealing with. Sewer gas is a potentially dangerous odor, so it’s essential to get it checked out. There are a few ways to do this, including hiring a plumber to do a drain pressure test or sending a remote camera through your drains.


While dehumidifiers can help reduce the moisture in a room, there are other steps you can take to remove the sewer gas smell in your basement. Firstly, you should determine what is causing the odor in your basement. If it is mold, sewer gas, or some other source, you should get it treated by a professional. Once this is done, you can focus on removing the odor and enjoying your basement once more.

Sewer gas is a foul smell that comes from the main sewer line. It is a dangerous gas containing a rotten egg odor. It is composed of a range of chemical compounds, including ammonia and carbon monoxide, and can be harmful to your health. If you notice a noxious odor in your basement, you should act immediately.

If the smell is caused by mold, it is likely that you have some type of leak. While you can treat small areas of mold with a water and bleach mixture, a larger area will most likely need to be treated by a professional. However, dehumidifiers can help keep key areas of your home dry and mold-free. If you’re not sure whether a dehumidifier is right for your home, you may want to seek a professional opinion before you make a decision.

A dehumidifier can also help improve the air quality in your basement by reducing the humidity. It can also reduce the growth of mold and other allergens. They are relatively inexpensive and can be easily installed. Remember to maintain the unit regularly. And remember that if you’re using one to eliminate sewer gas smell in basement, you’re going to have to spend some money on it.

If the odor is mainly caused by a wood based substance, sandpaper and a HEPA filter vacuum can help you get rid of the musty odor and dampness. In addition to the dehumidifier, you can also try essential oils to cover up the smell. Lavender is the most common oil used to mask this problem, but you can also use peppermint, tea tree, and eucalyptus oil.


If you’re experiencing a foul sewer gas odor in your basement, you’re not alone. You’re not alone, but there are a few things you can do. If the smell persists, the problem may be a simple plumbing issue. A broken or damaged P-trap can be the culprit, and a dirty or cracked floor drain can add to the problem.

You can try to remedy the problem yourself by filling the P-trap with water. Depending on which sinks and drains are affected by the odor, you can use a solution that contains bleach to help you get rid of the odor. However, be aware of its corrosive nature and wear safety goggles before using bleach. Do not add more than a cup of bleach.

To be safe, make sure you wear a face mask while searching for the odor. You may encounter spiders and cobwebs, so you need to have an effective way to remove them. While you may not need all of the supplies, you should make sure to wear protective gear, as you may be working in the presence of hazardous gases. Before beginning your search, make sure to check all of your plumbing fixtures for leaks or clogs.

A broken P-trap is most likely the source of the sewer gas smell. This problem can affect the whole house, as well as the bathroom. Luckily, the basement is designed with a floor drain that connects to a sewer line. This drain channels excess water from the floor to the sewer line. Every drain line connected to the sewer system in your house must have a drain trap. These traps can be found in the plumbing system. Using a P-trap is one of the quickest and easiest ways to eliminate the odor.

Another solution is installing a P-trap. This plumbing device is a U-shaped trap that traps water underneath the sink. By installing one, you can prevent sewer gas smells from entering your home. In fact, this plumbing solution can even save you money by eliminating the smell. If the P-trap is not installed properly, the sewer gas smell may continue to persist. If the P-trap is not installed correctly, you should consider replacing it.

Fixing a Broken Sewer Line

Sewer gas is an unpleasant odor that can invade your home for a number of reasons. Sewage gas can cause serious health problems, including headaches and constant infections. Even worse, sewer gas can make your basement smell rotten. To fix the problem, you should first repair the sewer line, which is often hidden underneath flooring or walls. In addition to replacing the line, you should also inspect the pipe for cracks and leaks.

Another cause of the smell is a broken or cracked sewer line. This is a job best left to a plumber, as doing it yourself can make the problem worse. Once you have identified the problem, the plumber will use a sewer camera to check for any leaks or breaks in your line. Once he or she detects the problem, you can either make the necessary repairs or call a plumber to help you.

The problem could also be related to other plumbing fixtures in your basement. In case the floor drain isn’t vented, the water in the P-trap will eventually evaporate. If the problem is a broken sewer line, you can simply dump water down the floor drain. However, this solution won’t work if the smell is coming from other basement fixtures. Luckily, there are a few simple steps you can take to fix a broken sewer line and get rid of sewer gas smell in basement.

In addition to the above-mentioned solutions, you can also try a pipe lining method. Pipe lining involves inserting an inflatable tube covered with epoxy into the damaged sewer pipe. The tube is then inflated to apply pressure on the existing sewer line. After the epoxy hardens, the tube can be removed and the damage repaired. The procedure is quick and easy, and you’ll be able to start enjoying your home again in no time!

Another solution to a sewer gas smell in basement is to repair the floor drain. The floor drain is fitted with a cleanout plug to prevent the sewer gas from leaking into your basement. A clogged floor drain is often the culprit. Fortunately, a cleanout plug can be purchased at any hardware store. However, it’s recommended that you contact a plumber immediately if the smell persists.

Cleaning a Clogged P-Trap

The first step in eliminating a sewer gas smell in your basement is to check your basement exhaust fans for any obstructions. Sewer gas can cause headaches, nausea, and dizziness, and in some cases can even cause unconsciousness. To eliminate this problem, you can clean your P-trap and try to run your exhaust fan to remove the gas. If this doesn’t work, you can also check the vent pipes on your roof.

If the floor drain is causing a sewer gas smell, it may be a simple matter of clearing the drain. A pitcher of water will clean out the floor drain and restore its proper function. In addition to clogged drains, the floor drain can also cause sewer gas smell. If this is the case, you can replace the drain cap with a new one from a hardware store.

Another reason for the sewer gas smell in basement is a clogged P-trap. During the winter, the P-trap may become dried up, allowing sewer gasses to enter. It’s also possible that the smell comes from a floor drain or a less-used sink or toilet. If the sewer smell continues, call a plumber and have it fixed.

If you’re not sure what’s causing your sewer gas smell, you can try a half-gallon of water in the P-trap. Adding half-a gallon of water will restore the barrier, and it will prevent odors from permeating the drain. You can also try adding a cup of bleach to the water to kill any larvae. Be sure to wear safety goggles and never use more than one cup of bleach.

Another cause of the smell is improper ventilation. Sewer gas leaks can occur if there is a loose connection between your sewage vent pipe and your home’s plumbing system. The vent pipe should be free of debris and snow. If the pipe is not vented, you may need to hire a plumber to install the proper ventilation. If the vent pipe is not functional, remodeling may be needed. Clean the P-trap regularly to eliminate the smell.
