The smell of sewer gas can be quite overpowering and unpleasant, especially when it's coming from your bathroom sink. This is a common problem that can be caused by various reasons. One of the main causes is a dried out p-trap. The p-trap is a curved section of pipe that holds water and creates a barrier between the sewer line and your bathroom. When the p-trap dries out, it allows sewer gas to escape into your bathroom, resulting in that foul smell. Sewer Gas Smell in Bathroom Sink

How to Eliminate Sewer Gas from Your Bathroom Sink Drain
The Importance of Proper Drainage in House Design
When designing a house, there are many important factors to consider, such as layout, materials, and overall aesthetic. However, one aspect that is often overlooked is the drainage system. Proper drainage is essential for a functional and healthy home, as it helps to prevent water damage, mold, and unpleasant odors. One common issue that homeowners face is sewer gas coming from their bathroom sink drain. In this article, we will discuss what causes this problem and how to effectively eliminate it.
The Culprit: Sewer Gas
Sewer gas is a mixture of toxic and flammable gases that can form in your home's plumbing system. It is primarily made up of methane, hydrogen sulfide, and ammonia, which can cause a foul odor and pose health risks if inhaled. Sewer gas often forms in areas of your plumbing system that are not frequently used, such as a bathroom sink drain that is rarely used or has a partial blockage. When the water in the drain evaporates, it allows the gases to escape into your bathroom.
Causes of Sewer Gas in Bathroom Sink Drain
There are several reasons why sewer gas may be present in your bathroom sink drain. One common cause is a dry or partially blocked drain trap. This is the curved section of pipe under your sink that traps water and prevents sewer gas from entering your home. When the water in the trap evaporates, it leaves an opening for the gas to escape. Another cause could be a blocked vent pipe, which allows air to flow through your plumbing system and prevents a vacuum from forming. If the vent pipe is blocked, it can cause the water in your drain trap to siphon out, allowing sewer gas to enter your home.
How to Eliminate Sewer Gas
The first step in eliminating sewer gas from your bathroom sink drain is to determine the cause. If it is a dry drain trap, simply run some water into the sink to refill the trap. If the trap is partially blocked, use a plunger or a drain snake to clear the blockage. If the issue is a blocked vent pipe, you may need to call a professional plumber to clear the obstruction. Once the cause is resolved, the sewer gas should dissipate on its own. You can also pour a mixture of baking soda and vinegar down the drain to help neutralize any lingering odors.
Preventing Future Problems
To prevent sewer gas from becoming a recurring issue, it is important to properly maintain your plumbing system. Regularly run water through all of your drains, even those that are not frequently used. This will help to keep the water in the trap from evaporating. It is also a good idea to have your plumbing system inspected and cleaned by a professional plumber at least once a year.
In conclusion, sewer gas in your bathroom sink drain is not only unpleasant, but it can also be hazardous to your health. By understanding the causes and taking proper preventative measures, you can eliminate this problem and ensure a safe and healthy home. Remember to always prioritize proper drainage when designing or maintaining your house for a functional and comfortable living space.
