There could be a couple of reasons, but the most likely is that the water traps in your tub/shower, sink or toilet are not working properly. A water trap (pipe looks like the letter "J") blocks the sewer smell from coming up... Maybe there is a leak in one of your J-traps?
I recently stayed at a hotel that had exactly this problem, except it wasnt a leak... When a neighboring room would flush the toilet, it would create a vacuum and suck the water out of our trap... we just had to run the water a little to refill the trap. add a comment
