: I have a briggs toilet in a second bathroom which was not being used very muchy, and I now have a strange smell coming from it. A salesperson in a plumbing store said since it wasn't flush much, there's something with the water in the "trap" which causes the sewage smell to come up. I live on the third floor of a nine story building. Another poster get rid of toilet odor by raising the water level and using bleach. Any suggestions?
You cannot raise the level of the water in the bowl.The water does evaporate over time and the sewer gas can be let out.Simplest solution would be to flush the toilet more often.
