Hi and thanks for this great site!
I need to ask a question. My Mom has a built in dishawasher and garbage disposal, there is a sewer smell coming from the dishwasher. They have had smoke tests done, everyrhing came out ok on that. They went and bought a new dishwasher, had it installed and the smell is still there. So I went and put all new pipes under the sink thought that might be it, it wasn't.
Where can we go from here?
Thanks so much for all your help!
