We moved into our house in the country this summer, and our well water is stinky. Its not stinky out of the tap, but when its run a long time like for showers or laundry, the house smells. Its worse with hot. I know what iron smells like, its not that, and it isn't rotteneggs sulfur smell. But its kinda fart-y. Not overwhelming, but noticeable. Problem? Not? Suggestions?
