Your Question– “I have a sewer smell coming from the drain of a broken shower. What is this smell? We moved in January 2012 and haven’t had any issues with a sewer smell until today. We don’t use this shower because the pipe leaks into our dining room and I can’t afford to get the pipe fixed yet.”
Our Answer- In our opinion, it is possible that the water has evaporated from the trap since the shower has not been used. We recommend pouring water down the drain to refill trap.
