Where would the smell of sewage in basment come from?
Help! My basement suddenly developed the smell of rotten eggs or even worse, raw sewage. I can’t tell. The smell seems to be coming in somewhere around where the sewer line is in the front of the basement, though I can’t say for sure where it is. Seems to be there, but the smell travels a bit with air currents. NOTHING is showing signs of a sewer line back up. The basement toilet would ordinarily be the first place that this would show, and it’s flushing just fine. All toilets are flushing, all drains emptying and nothing is backing up. I went outside but can detect no odor out there. It smells horrible in here, and I’m venting the house. This all started very suddenly yesterday morning and the odor grew stronger all day long. Could I have a sewer line break outside that’s causing this odor INSIDE the basement???????
