Tried that just now and the smell in the sink is gone. The smell underneath the sink is there but much fainter. The air admittance valve has been glued on. Would like to replace, any ideas on how to get it off?Re: Sewer smell when using exhaust fansThanks for all the suggestions and ideas. We live full time in our RV. Most of the folks here leave their gray line open until it's time to drain the black tank. They don't have the problem we are having. Day before we empty black tank, we close the gray tank, use the deodorizer, then flush line with the gray water. Have tried putting water in sinks when running the exhaust fan that's when the smell comes from under the kitchen sink.Sewer smell when using exhaust fansHave 2014 Open Range Journeyer. When we use the exhaust fans there is a terrible sewer smell coming from kitchen drains and the cabinet underneath. Black line is closed, grey line is open. We use a grey water deodorizer. Any suggestions as to the cause or how to end this smell?
