I recently had a bathroom installed in a newly constructed one bedroom apartment. Ocassionally I will smell strong gases or odors coming from around the toilet base. The shower and sink are also connected to the same main sewer line which drains into a septic tank. Toilet, sink, and shower are vented. There are no ordors or gases coming out of the shower floor drain or the sink drain. I'm wondering if the a wax seal was not installed or not installed properly when the toilet was being installed? Or could there be another issue?
Thank you Confused
