How to Remove Sewer Smell From Bathroom Sink

A sewer smell in your bathroom sink can be a frustrating and embarrassing problem. The good news is that it is usually a relatively easy fix. Here are a few things you can try to get rid of the smell:

1. Check the P-trap. The P-trap is a U-shaped pipe that is located under the sink. It is designed to hold water, which creates a seal that prevents sewer gases from escaping into the bathroom. Over time, the P-trap can become clogged with hair, soap scum, and other debris, which can cause the seal to break and allow sewer gases to escape.

To check the P-trap, remove the drain stopper and look inside the pipe. If you see any debris, use a pair of pliers to remove it. Once the P-trap is clear, run some water down the drain to refill the trap.

2. Clean the drain. If the P-trap is clear, the next step is to clean the drain. You can do this by pouring a cup of baking soda down the drain, followed by a cup of vinegar. Let the solution sit for 15 minutes, then flush it down the drain with hot water.

The baking soda and vinegar will help to break down any buildup in the drain, which can be causing the sewer smell. If the smell persists, you may need to use a commercial drain cleaner. Follow the directions on the bottle carefully.

3. Check the vent pipe. The vent pipe is a pipe that extends from the bathroom sink to the roof. It is designed to allow sewer gases to escape from the plumbing system. If the vent pipe is blocked, sewer gases can back up into the bathroom sink and cause a smell.

To check the vent pipe, go outside and look for a pipe that is sticking out of the roof. If the pipe is clogged, you may be able to clear it by using a wire hanger or a plumber's snake. If you are unable to clear the blockage, you may need to call a plumber.

4. Call a plumber. If you have tried all of the above steps and the sewer smell still persists, you may need to call a plumber. A plumber can inspect the plumbing system and identify the source of the smell. They can then fix the problem and prevent it from happening again.
