Help! We have a terrible sewage smell coming from under our kitchen sink. We have had
A plumber come 3 times. They thought it was the studor vent and replaced it but the smell
Continues. Today another plumber came and thought maybe the new studor vent was
Defective after he got to checking it and he replaced it again. The have checked for leaks,etc. but can't seem to figure out what is going on. The smell is only under the kitchen sink and you can only smell it if you open the doors. It has been going on for
Several months now. :confused:

If the Vent checked out OK then I could be a drainage pipe leaking inside the wall. How old is your home? Is the drainage metal or plastic? Back to you, Tom
