Greetings! Got a sewer gas issue in a downstairs bathroom. Layout is this from left to right: bathtub, toilet, double vanity sink. Then a half bath right next to it with another vanity, then toilet. I have replaced wax seals on both toilets, but this hasn't seemed to help. It seems that the smell is coming from under the vanity sinks on the right. I have made sure there is water in all p-traps and roof vent is clear. One plumber came out on a day when there smell wasn't particularly strong and didn't seem to notice it much. Suggested taping sink drains to try to eliminate and identify source of the smell. This hasn't worked. Smell hasn't really gotten better or worse. All three sink drains are taped, wax seals replaced. There are no studor vents under the sinks. Any thoughts, ideas? Thanks! G$
