If your bathroom has a sewage smell, it is important to clean it as soon as possible. This type of odor can be caused by many things, including a clogged sewer line or vent, drain problems, or a septic tank issue.

Assuming that the cause of the sewage smell is a clogged sewer line or vent, the first thing you need to do is find the source of the blockage. This can be done by using a plumber’s snake or a drain auger. Once you have found the source of the blockage, you can begin to clear it out.

If the cause of the smell is drain problems, there are a few different things that you can do. First, make sure that all of your drains are clear and free from debris. If they are not, use a plunger or a small hand-held drain snake to remove any blockages.

Once your drains are clear, you can flush them with hot water to remove any lingering odors. You can also pour baking soda down your drains and follow it with vinegar. Let this sit for an hour before flushing with hot water again.

If you have a septic tank, it is important to have it pumped on a regular basis. If your tank has not been pumped in awhile, this could be the cause of your sewage smell. Contact a professional septic company to have your tank pumped and inspected.
