A rotten egg odor is one of the most common signs that there’s something wrong in your home. A few of its most common sources include a natural gas leak or a problematic electrical system. In addition to that, rotten egg odors can also come from your water. Whether you’re using city water or well water, this can happen to anyone.

While your first reaction may be that your water source is contaminated, that is often not the case. The rotten egg odor is caused by sulfur bacteria that change sulfates in the water to hydrogen sulfide. Even just the tiniest amounts of these can cause your water to start smelling. In addition to its strong unpleasant odor, it can also slightly alter the taste of your food and even cause discoloration on your kitchen and bathroom fixtures. Fortunately, it is not a health risk. Despite its smell, it’s perfectly safe to drink. It simply provides an annoyance for you and other people using it. Now, let’s take a look at how to get rid of it.

Rotten Egg Odor: Find the Source

There are a number of ways that rotten egg odor can appear in your water supply. Before coming up with any solutions, you have to determine the source first.


This is one of the most common places for bacteria to grow. Given all the food waste that accumulates there, the bacteria have plenty of sources of nutrients to grow and multiply. To make sure if the smell is coming from your drain, fill a glass of water from your sink then step away from the area. If the tap water doesn’t have any smell, the problem is coming from your drain.

Water Heater

Sulfur bacteria can also grow in water heaters that haven’t been used or that have been turned off for a long period of time. They can also grow there if the heater’s thermostat is set too low. However, this is the case only if it’s just the hot water that smells and not also the cold water. More often than not, this comes from a magnesium heating rod in the hot water tank.

Water Source

If both your hot and cold water smells and if the smell is coming from faucets around your home, the problem is most likely coming from your water source. One cause of this is that there may be an improperly located or defective septic system near your water source. On the other hand, if you get your water from a well, the natural groundwater chemistry of it might be supporting bacterial growth. If this is the case, it might be best not to use the water since it may contain other harmful bacteria.

How To Get Rid of the Rotten Egg Odor from Your Water

Fortunately, that rotten egg odor from your faucet doesn’t have to stay there for long. There are plenty of ways you can get rid of them on your own or with the help of professionals depending on the source of the problem.

Clean Your Drain

If the problem is in your drain, you can try getting rid of the problem by flushing and disinfit. Pour half a cup of baking soda down the drain then follow it with a cup of vinegar. Wait for around 15 minutes before washing it with hot water.

Clean Your Pipes

The smell can also cling to your pipes. To get rid of this problem, let the water run on all your faucets at home for about ten minutes. This will be enough time to clear out your pipes and get rid of the lingering scent.

Replace the Magnesium Rod

If the smell is coming from a magnesium heating rod, call in a professional to replace it with something like an aluminum rod instead.
