Does Your Water Smell Like Sulfur or Rotten Eggs?

Find everything you need to get rid of H2S and that sulfur/rotten-egg smell from your water with Culligan of Kansas City

Why Does My Water Smell Like Rotten Eggs in KC?

Usually, if your water smells like sulfur or rotten eggs, the reason is because your water has high Hydrogen Sulfide (H2S) content.

H2S is a gas that is released from the earth and finds its way into groundwater. It’s especially common in well water located near shale, sandstone, coal, peat, or oil.

(Occasionally, a rotten-egg smell in your water could also be caused by a water heater or by sewage pollution in your water. If you’re on city water, the most likely explanation is your water heater.)

corrosion
H2S dissolves in water to create a weak acid that can corrode metal pipes

Negative Effects of H2S

In addition to potential health risks, having H2S in your water can cause all sorts of annoying problems. H2S in your water can:

  • Cause coffee and tea to be discolored and taste funny
  • Corrode metals (steel, copper, iron, brass), including silverware
  • Cause foods cooked with water to taste “off”
  • Create yellow or black stains in your bathroom and kitchen 

How Do You Fix It?

Here at Culligan, you can find everything you need to get rid of H2S and that sulfur/rotten-egg smell from your water.

The first step we have to take is to test your water, so we can be sure of the real cause of the rotten-egg smell.

Fortunately, here at Culligan we offer this service free. One of our water experts will come to your home to test the water (you can’t send it away to a laboratory because H2S is a gas and could dissipate during transport) and let you know the source of your rotten-egg smell. You’re under no obligation whatsoever.

I'm happy and this is a long review. The TL;DR is that they're awesome.I can't recommend Culligan of KC enough. Truly, they have been phenomenal. Sales, installation, even the managers I've spoken with were all just friendly, knowledgeable, and helpful. I have a special needs kid and am fairly new to Kansas City, and I was not prepared for how hard and chlorinated the water in Olathe is. My kid has severe digestive issues and skin issues and is super sensitive to all kinds of things, so I finally decided we needed a water softener and RO.Justin came out and tested my tap water for all the things (it's as bad as I thought) and explained all my options really well, helping me decide what I really needed for my house and my budget without pressuring me. Honestly, a wonderful salesman. The kind of salesman that all salesmen should be but rarely are. He's answered all my questions (and I have had a lot), returns messages and calls with no problem or delay, and is just a great guy to work with.Josh installed my equipment a week or two later, and was super professional and efficient. He got my water softener, dechlorinator, and RO all hooked up and installed with no issues, and then made sure I understood the equipment and operation of all the things. Justin popped in during installation and made sure I was happy with everything and they were just really great.Justin came back a couple weeks later to make sure everything was going well and I was happy with everything and the equipment was working as it should (it was). I decided that I needed a larger RO tank (I use more than I estimated) and he came through again, explaining my options and getting me what I needed.Damien came and installed my larger RO tank, and was super great about working around my schedule. He was friendly and efficient, replaced my tank quickly with no issues.If you're worried about your water, these are the guys to call, hands down. I have recommended them to strangers, to my family, and will continue to be a customer here.

We’ve had our new water system for about three weeks and could not be happier. Love the feel and taste of our water. Justin and Josh were both excellent in their sales and installation roles and I would highly recommend Culligan KC for their products and people. Great work, all!

Justin and Josh did a great job last Friday May, 29, 2026 putting my system in particularly with the changes that were made. We went from the big blue to the whole house filter system during their installation and Josh had to go to the store to pick up parts so the water from the softener could be discharged in another area of the basement instead of the original spot. Thanks you!

Kuddos to James and his team. My wife and I are very happy with the service we are receiving.We recently had a wholehouse water softening and reverse osmosis system installed.James personally made sure that the installation was tailored to meet our needs despite some obstacles we had to overcome in the early stages of the planning and installation given the plumbing system layout of the house.James and his team delivered, and then some. They went above and beyond. That explains Culligan's excellent reputation in the local market.People make the difference for companies for sure.Thank you James and Culligan team.
