Bathroom Sink Drain Smells Like Sewer

There are few things more off-putting than a smelly bathroom sink drain. That nasty odor can make brushing your teeth or washing your hands a less than pleasant experience. Plus, it can be a sign of a more serious plumbing problem.

If your bathroom sink drain smells like sewer, there are a few things you can do to try to fix the problem yourself. First, try pouring a cup of baking soda down the drain, followed by a cup of vinegar. Let it sit for a few minutes, then flush it with hot water.

If that doesn't work, you can try using a commercial drain cleaner. Be sure to follow the directions on the bottle carefully. If the smell persists, you may need to call a plumber to take a look.

There are a few things that can cause a bathroom sink drain to smell like sewer. One possibility is that there is a clog in the drain. This can be caused by hair, soap scum, or other debris. Another possibility is that the P-trap, which is the U-shaped pipe under the sink, is clogged.

If the clog is in the drain, you can try to remove it yourself using a drain snake. If the clog is in the P-trap, you will need to remove the P-trap and clean it out. You can also try pouring a cup of bleach down the drain to kill any bacteria that may be causing the smell.

If you have tried all of these things and the smell still persists, you may need to call a plumber. A plumber can use a camera to inspect the drain and P-trap to see if there is a clog or other problem. They can also clean the drain and P-trap for you.

Here are some tips to help prevent your bathroom sink drain from smelling like sewer:

Run hot water down the drain for a few minutes every week to help keep it clean.
Avoid pouring grease or oil down the drain.
Use a drain strainer to catch hair and other debris.
Clean the P-trap regularly.

By following these tips, you can help keep your bathroom sink drain smelling fresh and clean.
