It smells like someone has the worst stomach sickness of their lives. We did recently have a bathroom remodeled but our crawl space is bone dry. One friend suggested it could be our hvac condensation line but we’re not sure. What could this be?
Toilet seal? Are you running your exhaust fan over stove or in bathroom? Maybe there’s negative pressure that’s sucking sewer gas in. I know from experience.
