Harmful effects of Rotten Egg Smell

The reason behind the rotten egg smell is the hydrogen sulfide. And smelling it doesn’t mean it will make you sick.

To get rid of the foul smell, follow the below solutions we provide.

5 Issues and Remedies of Rotten Egg Smell in the House

From this chapter, you can know the 5 issues for the rotten egg smell. Also, we provide the solution to those problems. So, let’s jump into the point straight.

Issue 1: Gas Leaks

The first and foremost reason behind the rotten egg smell is the gas leaks. So, check out any gas appliances like water heaters, stove, and valves.

Generally, the smell comes from those areas because of Hydrogen Sulphide. Gas company injected this so that you can trace out the leaky spot easily.

The gas leak occurs due to a bad regulator. Also, if the gas line in your house doesn’t install according to the local codes, the leaks happen frequently.

Solution

Gas leak is a serious problem. Keep away the open flame and electric equipment from the gas line. Then, call the gas company to do this task for you.

Issue 2: P-trap under the drain dries out

Rotten egg smell is a constant issue!! Then, it’s probably because of the dry P-trap. Every drain of your house has a P-shape pipe that holds some water. This pipe is known as P-trap.

The water in this pipe blocks the sewage smell of the sewer line from leaking out into your home. If you leave the sink or shower for a long time, then water in the pipe will dry out.

And every time you go to use the shower, you start getting the rotten egg smell. This is because there is no barrier between you and the sewer pipe.

Solution

To get rid of this stench, run your shower for 2 minutes, run the bathroom fan for 20-30 minutes.

Issue 3: Faulty Vent Pipe

Vent pipe in your home plumbing system is a crucial piece of equipment that controls the air pressure. Therefore, it helps to direct the smell outside of your home.

But the faulty vent pipe directs the odor inside of the bathroom or interior of the house. And every time you go to the bathroom, you smell the hideous odor.

Besides, improper installation of the vent pipe will be another reason for the rotten or sulfur smell.

Solution

If the vent pipe gets clogged, we recommend you cut the clogged part. Then, attach a stud-or vent there.

Still, the odor is there after cutting the clogged pipe, flushing the entire vent pipe will get rid of this issue. 

In case of improper installation, we suggest you hire a professional plumber to install the vent pipe.

Issue 4: Biological Slim

Another reason behind the sewage odor is the biological slim. This slim can generally grow in the sink, bath drain, and shower tubs. It occurs because of skin oil, hair shampoo, and soap.

For the slim, every time you flush the drainpipe, you smell the stink odor.

Solution

First off, remove the drainpipe cover and flush water into the tubes. 

Then, use a scrubbing brush and brush away the pipe with soap. 

Lastly, flush with water to get rid of the rotten smell.

Issue 5: Well Water

Do you have a well or municipal water? If you have a well, then the foul odor comes from the water because of the hydrogen sulfide buildup. As there are bacteria in the well, the water just smells. But it is not harmful. 

Solution

You can effortlessly get rid of this issue by shocking the well with chlorine. Also, hiring a plumber to install a carbon filter on the faucets will be excellent to remove the foul odor from water.
