Check The P-Trap

If you notice a sewer gas smell in your bathroom, you should first check the P-trap.

The P-trap is a U-shaped pipe that is located under the sink.

It traps water to prevent sewer gases from entering your home.

If the P-trap is dry, it may be allowing sewer gases to escape.

To fix this, pour a few cups of water into the P-trap and wait a few minutes to see if the smell goes away.

Inspect The Vent Stack

Another potential cause of a sewer gas smell in your bathroom is an issue with the vent stack.

The vent stack is a pipe that runs from the drain up through your home’s roof.

Its purpose is to allow air to enter the drain so water can flow freely.

If the vent stack is blocked, it can cause sewer gases to build up in your bathroom.

To inspect the vent stack, remove the cap and look for any blockages.

Replace The Wax Ring

If you have checked the P-trap and vent stack, and neither seems to be the problem, then it is likely that the issue is with the wax ring.

The wax ring is a seal that is located between the toilet and the drain pipe.

Over time, it can become dried out or cracked, allowing sewer gases to escape.

Simply remove the toilet and install a new one to replace the wax ring.

Call A Plumber

If you have tried all these things and still notice a sewer gas smell in your bathroom, then it is time to call a plumber.

A plumber can identify any problems with your plumbing that may be causing the issue.

They will also be able to make any necessary repairs or replacements to get rid of the smell for good.

What Causes Sewer Gas Smell in Bathroom?

What Causes Sewer Gas Smell in Bathroom?

A few different things can cause sewer gas smell in the bathroom.

One of the most common culprits is a dry P-trap.

The P-trap is a U-shaped pipe that’s located under your sink.

Its purpose is to hold water to create a seal that prevents sewer gas from escaping through the drain.

If the P-trap doesn’t have enough water in it, the seal is broken, and sewer gas can escape.

Another common cause of sewer gas smell is a cracked or broken vent stack.

The vent stack is a pipe that runs from your drains up through your roof.

Its purpose is to allow fresh air into the drainage system so that the wastewater can flow freely.

If the vent stack is cracked or broken, sewer gas can escape and make it into your bathroom.

Finally, another possible cause of sewer gas smell is a blockage in the main sewer line.

If there is a blockage, sewage can back up into your home and cause a very unpleasant smell.

If you think you may have a blockage, it’s best to contact a professional plumber for help.
