How To Fix Sewer Smell In Bathroom Sinks And Drains

Does your bathroom smell like a sewer? If so, you’re not alone. Many homeowners experience this issue at some point. In this blog post, we’ll discuss the possible causes of sewer smell in bathroom drains, sinks, and showers. We’ll also provide some tips for preventing the smell from occurring in the first place.

Common Causes Of Sewer Smell In Bathroom Drains, Sinks, And Showers

Below are some common causes of sewage smell in the bathroom:

1. Dry P-trap

A dry P-trap is one of the most common causes of sewer smell in your bathroom. The P-trap is a U-shaped pipe located under the sink or drains. It is used to trap water beneath the drain, preventing sewer smells from reaching the bathroom.

If you do not use your bathroom sinks regularly, there is a possibility that the water in the P-trap will dry out, allowing sewer gases to flow freely into your bathroom.  Fixing this problem is simple. Just run some water into the bathroom sink for a minute or so, and the problem is fixed.

2. Vent Stack / Vent Pipe

The vent stack is a pipe that goes through your roof and allows air to enter the sewer system. This pipe also prevents sewer gases from entering your bathroom. If the vent stack becomes blocked, it can cause sewer smells to waft into your home.

There are a few ways you can clear a blocked vent stack. You can use a garden hose to flush out any debris that may be blocking the pipe. You can also use a plumber’s snake to remove any blockages.

3. Leaky Gaskets Or Fitting

If you have leaky gaskets or fittings in your bathroom, it could be allowing sewer gases to escape into the room. Over time, these gaskets and fittings can become loose, allowing sewage to seep through. If you suspect this is the case, it’s best to call a plumber to take a look. They will be able to tighten or replace any faulty gaskets or fittings properly.

4. Sewer Line Break

If there is a break in your sewer line, it could be causing sewer odors to enter your bathroom. This is often caused by tree roots growing into the pipe and breaking it. If you think this may be the case, you’ll need to call a professional plumber to come and take a look.

5. Shower Drain Clogs

Clogged drains are another common cause of sewer smell in the bathroom. If your shower drain is clogged, it can cause water to back up and eventually lead to sewer smells. To unclog a shower drain, you can use a plumber’s snake. If you have a lot of hair in your drain, you may need to remove it with a pair of pliers.

Preventing Sewer Smell In The Bathroom

There are a few things you can do to prevent sewer smell from occurring in your bathroom:

1. Use Your Bathroom Regularly

If you don’t use your bathroom often, the water in the P-trap can dry out, leading to sewer smells. To prevent this, make a point to use your bathroom regularly, even if it’s just for a quick wash.

2. Don’t Pour Fats Or Oils Down The Drain

Fats and oils can solidify in your drains and eventually lead to clogs. This can cause water to back up and lead to sewer smells. As a preventative measure, don’t pour fats or oils down your bathroom drains.

3. Clean Your Drains Regularly

Clogged drains are one of the most common causes of sewer smell. To prevent this, clean your drains regularly with a plunger or a drain snake. You can also use a mixture of baking soda and vinegar to clean your drains and freshen them up.

4. Let Some Fresh Air In

Sewer gases can build up in your bathroom if it’s not well ventilated. We recommend making sure to open a window or turn on the exhaust fan when you’re using the bathroom. This will help to circulate fresh air and reduce the chances of sewer smells.

5. Call A Professional If You Have Any Concerns

If you smell sewage in your bathroom, it’s best to call a professional. They will be able to inspect your bathroom and identify any potential problems properly.
