My toilet upstair started to stink -sewage smell. I trouble shot it by wrapping the toilet with ceram plastic wrap to pinpoint the problem. Once it was wrapped there was no more smell. I thought that it might be the wax ring but 1 day later the toilet downstairs starts to smell the same way. Before wrapping the top toilet, the 1st floor toilet did not smell. Could it be the vent???
