 Sulfur Facts

 

Why does my water smell like rotten eggs?

The "rotten egg" smell that occasionally comes from your faucet is likely hydrogen sulfide. Hydrogen sulfide (commonly called sulfur) odors often present themselves in a homeowner’s hot water. Sulfur is a mineral, that like many other minerals, exists in the ground, and is dissolved in the well long before being pumped out of the ground. Even though this odor is a nuisance, the water is safe for consumption with low levels of sulfur.

What can I do to help control the odor?

There are several different steps you can take to help alleviate the odor. The first thing to try is to turn on the hot water throughout your home and let the water run until cold. Doing this flushes out the water heater and will eventually lessen the odor. You may have to do this more than once, and you may need to do it periodically to keep the tank flushed out. Another thing you can try is to have a plumber remove the magnesium corrosion rod from your water tank and replace it with an aluminum rod. The factory installed magnesium rod in water heaters causes the dissolved sulfur to precipitate into a gas, causing the odor at the faucet. Water heater chlorination can also be done, however if you are unsure of how to do this, you should hire a qualified plumber.

Why does the cold water smell like sulfur as well as the hot water?

Chances are you smell the remnants of the hot water, and if you allow the cold faucet to run longer, the odor should disappear. Your outside faucets are plumbed directly to cold water, and there likely will not be a sulfur smell on those faucets. That will help you to determine if the source is your water heater.

What if the odor doesn’t go away?

Please feel free to contact Mark Chandler to discuss the problem you are having. Even though we won’t be able to enter your home and work on your plumbing, we will gladly discuss the issue with you and provide you with as much information as possible on how to alleviate the odor.
