My Bathroom Sink Smells Like Sewer

A smelly bathroom sink is a common problem that can be caused by a variety of factors. The most common cause is a buildup of hair, soap scum, and other debris in the drain. This can create a breeding ground for bacteria, which can lead to unpleasant odors.

Other causes of a smelly bathroom sink include:

A clogged drain
A leaking pipe
A faulty P-trap
A problem with the sewer line

If you have a smelly bathroom sink, there are a few things you can do to fix the problem. First, try cleaning the drain with a drain cleaner. If that doesn't work, you may need to call a plumber to snake the drain or repair the pipe.

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

Clean the drain regularly with a drain cleaner.
Avoid putting hair, soap scum, and other debris down the drain.
Run hot water down the drain for a few minutes every day to keep the pipes clean.
If you have a garbage disposal, run it regularly to keep the blades clean.
Inspect the P-trap under the sink regularly and clean it if it becomes clogged.

If you have tried all of these tips and your bathroom sink still smells like sewer, you may need to call a plumber. There may be a more serious problem with the plumbing or sewer line that needs to be addressed.

Additional Tips:

If you have a double sink, try closing the stopper on one side and filling the other side with hot water. This will help to flush out any debris that may be stuck in the drain.
You can also try using a homemade drain cleaner made from baking soda and vinegar. Pour 1/2 cup of baking soda down the drain, followed by 1/2 cup of vinegar. Let it sit for 30 minutes, then flush with hot water.
If you have a garbage disposal, try grinding up some citrus peels or ice cubes to help clean the blades and remove any odors.

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