2013 Landmark Key Largo. Have a major sewer gas problem. Used to be only a real problem when we flushed the toilet. This weekend when we opened up the doors to the basement it was unbearable. Had the AC units running all weekend. No smell under the vanity or kitchen sink. I read all of the other issues about this and I am puzzled because of the overwhelming smell in the basement. A visual look at the piping in the belly provided no solution. Fuel for thought: we are stationary on our property and have a pump out service come to empty the tanks. Not sure if the suction of that has anything to do with this.
