We were experiencing a sewer smell as we exited the shower. I opened the cabinet below the lavatory and was almost consumed with the smell. I removed the air admittance valve and found one at Home Depot cost about $6.99. It didn’t stop the smell. Located another at Home Depot, Oatly brand about $12. It worked and stopped our problem. Don’t waste your money on the cheap one.
I replaced all of ours with the $7 Oatey model when our rig was new. The ones that come in RVs are typically the cheapest available. I think one of them may have become faulty after 6 years now. So I'm researching what will be a better replacement. Studor generally has a good reputation but I have read better reviews about the Oatey models.
