Water is a vital part of life for drinking, cleaning, cooking, and bathing. But does the water in your home smell like rotten eggs? The cause of the odor is usually hydrogen sulfide gas or sulfur bacteria, typically in a house or building’s water supply. Nonetheless, it’s prevalent for people to experience different smells from tap or well water.
The Water Smell May Come from Your Water Supply
Sometimes we mistake the disagreeable odor from a drain for an unpleasant odor in the water. Smelly sinks normally occur due to bacteria developing in the sink drains. Make sure to complete the following steps to determine if the smell is coming from the water:
- Fill a glass of water and walk out of the room with it to smell it
- Begin searching for the source if you determine it is the water
- The smell most likely comes from your water supply if is prevalent in both the hot and cold water.
What is the Source?
Your water smells like rotten eggs because it potentially contains hydrogen sulfide. Even small amounts can still release a foul odor. Understanding the odor’s source is one thing, but looking for it is another. The best way to identify the problem is through elimination.
Is Your Water Heater the Source of the Bad Smell?
If your hot water supply smells like rotten eggs, it’s probably because of your water heater. However, if the odor is present despite your water’s temperature, the plumbing system is the reason. For example, you can have a problem with the smell of a specific drain in your property. Sometimes, the odor will distribute from one room or a single faucet.
Ways to Solve This Issue
Here are multiple ways to eliminate the smell of rotten eggs in your home:
- An ideal solution would be installing a house reverse osmosis water filtration system in your home. This system will boost the general standard of your water to remove the smell.
- Clean out your pipelines, as you may be able to permanently eliminate the odor. You can also achieve this by turning on every faucet on your property and allowing it to flow for 5-10 minutes.
- Lastly, determine the cleanliness of your water heater. Fill the storage tank when it is completely empty, increase the temperature to 160 degrees, and allow your heater to function for multiple hours. This is typically enough to remove any bacteria.
