Sewer smell inside RV....Help needed....
I have an issue with sewer smell inside my RV. I have done as others suggested and replaced the air admittance valves under my kitchen sink, and under my bathroom sink. I still have the sewer smell. ...

We learned early in our camping experience to keep the valve closed, and open only to empty. Otherwise smells do come up through the sinks. No reason to leave them open anyway, you want both tanks to be filled when emptied so you have a force of water flushing everything out.
