Sewage Gas Smell in Bathroom: Why It Happens and How to Fix It
If you've ever walked into your bathroom and been greeted by a foul sewage gas smell, you're not alone. This is a common problem, and it can be caused by a variety of factors. In this article, we'll tell you what causes sewage gas smell in bathrooms and how to fix it.
What Causes Sewage Gas Smell in Bathrooms?
The smell of sewage gas in your bathroom is caused by a variety of sources, including:
- Vents or pipes that are not properly sealed. When plumbing vents or pipes are not properly sealed, sewage gas can escape and fill your bathroom with its foul odor.
- Traps that are dry. P-traps are U-shaped pipes that trap water to prevent sewer gas from escaping. If the p-trap dries out, such as in a guest bathroom that is rarely used, sewer gas can escape.
- Clogged vents or pipes. If the vents or pipes that allow sewage gas to escape become clogged, it can back up into your bathroom.
- Broken or damaged pipes. If the pipes that carry sewage are broken or damaged, sewage gas can leak out.
How to Fix Sewage Gas Smell in Bathrooms
Here are some solutions on how to fix sewage gas smell in bathroom on some common causes:
- Seal any vents or pipes that are not properly sealed. You can do this using caulk or plumber's putty.
- Fill any dry p-traps with water. You can do this by running water in the sink or bathtub for a few minutes.
- Clean any clogged vents or pipes. You can do this using a drain snake or a wet/dry vacuum cleaner.
- Replace any broken or damaged pipes. This is a job best left to a professional plumber.
Preventing Sewage Gas Smell in Bathrooms
In addition to fixing the cause of the sewage gas smell, there are a few things you can do to prevent it from happening again, including:
- Run water in your drains regularly. This will help keep the p-traps filled with water.
- Clean your bathroom vents regularly. This will help prevent them from becoming clogged.
- Install a backflow preventer on your toilet. This will help prevent sewage from backing up into your bathroom.
If you've tried all of these solutions and you're still getting a sewage gas smell in your bathroom, it's important to call a professional plumber. There may be a more serious problem that needs to be addressed.
