Common Causes and Solutions to Smelly Water

Smelly Water

Smelly Water is no fun… Terminox™ may be the solution.

We often hear complaints of smelly water from potential water filtration customers. It’s usually described as a “rotten egg smell” or “sulfur smell”. While this is usually the case, there are times when the culprit is not actually sulfur itself. Water with high manganese levels can smell very similar to sulfur.

One of the easiest ways to differentiate between the two is to determine whether the hot water, cold water, or all water has a sulfur smell. Manganese typically presents a smell similar to a sulfur smell only on the hot water side, whereas sulfur typically affects the cold water. The presence of significant amounts of manganese can also cause discoloration ranging from grayish water to black slime in the water.

Terminox™ iron filters are self-backwashing units that require little to no maintenance to provide clean water free of odor or discoloration for years.

    i have that rotten egg smell, can i just put the clorox is the water softnor tank where the salt goes, how much on a standard tank?

      You can put clorox in the brine tank. However, you should only do this once a year, if that. There are other chemicals you can use aside from clorox that are “friendlier” to you and your system.

      If you’re looking to get a tank, check out our website for prices. If you have any more questions, don’t hesitate to call us at 1-800-701-9914. Thank you!

    I have well water and a Culligan water softener system attached. Bad smells from iron, sulfur or manganese may be the issue. Need assistance with a solution. Lived in house for over 30 years. Farm behind property was mined many years ago and looks like that water runoff is in my water system. Thanks. Dane

      Hi Dave,
      Sounds like a terminox would solve your problem. However, we first need some information about your water before we can make a recommendation. If you go to and look at items 7, 16, and 17, that’ll be all the info we need on your water to recommend the proper equipment. Should you have any questions, give us a call at 1-800-701-9914. Thank you and have a wonderful day.
