Question: I am getting a foul odor from a bathroom in the basement. We hardly ever use this bathroom except when we have company. This is embarrassing. What can we do?
Answer: Plumbing systems are designed to prevent foul odors from entering the house by means of the trap attached to fixtures. Traps contain water to seal out foul odors; if the water seal evaporates, the odors enter the house. To solve this problem, pour a bucket of water in each trap, sink, shower and floor drain. This will prevent the odors from entering the house.
