I really hope someone can help me here... I think my husband and I have tried EVERYTHING! We have a sewar smell coming from our toilet. We have a concrete floor and the carpet has been removed. We have replaced the wax ring 3 times. We have caulked the falange and the smell still broke through. We took the toilet out and noticed the toilet had the same smell so we bought a new toilet. Smell is here worse then ever! Our toilet is confined on the first floor in it's own little room in the bathroom and the smell is only located there. My husband looked down the wall at the pipe and there is no odor and the pipe is tightly connected. I don't know what else to look at! This has been going on for a year! HELP!!
