The P-trap is a curved section of pipe under your sink that is designed to hold water and prevent sewer gases from entering your home. If the water in the P-trap evaporates, it can create an opening for the sewer smell to escape. Pour some water down the drain to refill the P-trap and see if that solves the issue.2. Inspect the P-Trap

Troubleshooting a Sewer Smell Coming from the Bathroom Sink
Identifying the Problem
One of the most unpleasant and frustrating issues that homeowners may encounter is a sewer smell coming from the bathroom sink. Not only is it unpleasant to experience, but it can also be embarrassing if you have guests over. It's important to address this issue as soon as possible, as it could be a sign of a larger problem with your plumbing system. In this article, we will discuss the possible causes of a sewer smell coming from your bathroom sink and how to troubleshoot and fix the issue.
Possible Causes
There are several potential causes of a sewer smell coming from your bathroom sink. The most common culprit is a dry trap. Every sink has a U-shaped pipe known as a trap, which is designed to hold water and prevent sewer gases from entering your home. If the water in the trap evaporates, it can create an opening for the sewer smell to come through. This is more likely to happen in sinks that are not frequently used, such as in a guest bathroom.
Another possible cause is a clogged drain. If debris, hair, or other materials have built up in your sink drain, it can create a blockage that causes the water to drain slowly or not at all. This stagnant water can produce a foul odor, especially if it's been sitting for a while.
Lastly, a cracked or damaged sewer line can also be the source of the smell. If there is a leak or break in the sewer line, it can allow sewer gases to seep into your home and cause a strong odor.
Troubleshooting and Solutions
The first step in addressing a sewer smell coming from your bathroom sink is to check the trap. If the trap is dry, simply run some water down the sink to refill it. This should eliminate the smell. If the trap is not the issue, try pouring a mixture of hot water and baking soda down the drain to help dislodge any potential clogs. You can also use a plunger or drain snake to remove any debris or hair that may be causing the problem.
If these solutions do not work, it's best to call a professional plumber to inspect your sewer line. They will be able to identify any potential issues and provide the necessary repairs. It's important to address any problems with your sewer line as they can be hazardous to your health and cause further damage to your home if left untreated.
In conclusion, a sewer smell coming from your bathroom sink can be a nuisance, but it's important to address it promptly to avoid potential health hazards and further damage to your home. By identifying the cause and following the troubleshooting steps, you can eliminate the smell and enjoy a fresh and odor-free bathroom once again.
