In my toilet room, there is a toilet and a tankless bidet. There is a strong odor of sewer gas, starting yesterday. I inspected the back of both fixtures and found no cracks or other obvious entry points for the gas. The water seal in the toilet trap is at the proper height. The fixtures are caulked all around with no breaks where they sit on the tile floor. There doesn't seem to be any trap for the bidet Any suggestions as to the cause of the gas odor?
No announcement yet.
