I have a gas smell in the bathroom but it is not necessarily a sewage smell. I have had the vents checked with a smoke test and there were no leaks and it was venting properly. I put new wax rings on toilet and the smell is still there. Plumber cant figure it out. There is no smell in the attic, no smell under the house, no smell in kitchen or anywhere else. Smell gets worse in the afternoon but almost non existant in the morning. Also there is no Natural Gas in the bathroom.
Any thoughts would be appreciated. I cant stand it much more, its been present for months….Thanks!
