I am hoping someone can help me! This all started with an odor in a room that shares a wall with the bathroom. The bathroom, however, does not have an odor. The sewer vent goes through the wall in between, but I have cut into the drywall where the pipe enters the room and there is no smell. It could run under the floorboard, but I'm not sure. I have noticed now that the water level in the toilet slowly sinks throughout the day. There is no gurgle and it seems to flush normally. I have already had a plumber to the house, and he could not find anything wrong. I am thinking of pulling up a floorboard to see if there is a small leak under the floor. I have already pulled up the rug to see if it was mold... it was not. I am stumped and frusterated. PLEASE HELP!
