I am in the process of purchasing a new home- new construction. The inspector noted that there is Sulfur in water as indicated throught foul smell from kitchen faucet. I'm not sure if smell came from bathroom faucet. He said this is not a major issue but I'm nit sure. I requested that this issue be fix prior to closing. How do I make sure that this issue is fix other than not smelling the ordor when I tuen on the faucet?
