[:-yuck] Hello everyone. I am new to this forum. I came across this site looking for help with a problem. I live in a modular home that was just built in Nov. 2008. The guest bathroom water has an awful smell to it. Smells like sewer water or something. It is awful! I can only smell it when the water is running. The shower or toilet do not smell this way and no other sinks in the house do either. No one is drinking, brushing, or washing hands from this sink at the moment. Should I call a plumber? We have a well and have been having problems with lime and rock build up in the screens on faucets, the washer etc. Any connection between the two??? THX!
