Question DetailsAsked on 3/2/2012

How do I find the cause of and get rid of a rotten egg or sulfur smell in our hot water?

Our hot water has a strong rotten egg/sulfur smell. (I think it's also present in the cold water, but to a much less noticeable extent.) The smell is present from every faucet in the house. We have well water connected to a Kinetico water softener as well as a sediment and charcoal filter on the water line.

I've heard various opinions on what could cause the smell, including: a chemical reaction between the water and anodes in the electric water heater, sulfur gas present in the water, and bacteria in the water heater.

How do I get to the bottom of this and get a solution to the smell in place? Would I need to contact a plumber, water softener company, or someone else? I'd like to know what's causing it if it all possible and fix the actual issue rather than relying on trial-and-error to get rid of the water smell.

Thanks so much for any help!

Have you had your water supply tested for sulpher content and chemicals? That would be my first step. There are some treatment systems available that can help reduce the sulpher smell but you need to find out if it is a supply issue or if you have a significant deposit in your water heater. This is a fairly common problem with well water. The water heater makes it more pungent and noticeable. Call a testing company to check your supply. They can also make the best recommendation for your situation. Some well services offer testing. Your local environmental control office can help you test it or recommend someone.
