We bought a house 2 years ago that was approximately 2 years old. It has a septic tank. Lately I've been smelling an odor in my master bathroom (stronger in the morning) and now I'm starting to smell it in my master bedroom. The master bedroom and bath are on the opposite side of the house from where the tank is. The smell is getting worse. I've been reading what I can on septic tanks but no one has said anything about an odor only sludge backup. Could there be something wrong with the system? What should I do?:confused:
