After 4 to 5 years trouble-free, we're now frequently smelling sewer gas from the bathroom vanity sink. The only thing I can think of is that the p-trap must be siphoning out. Is it because the 13" length from the bottom of the sink to the bottom of the p-trap is too long?
It's been 6 years since this remodel, but I'm pretty sure the dwv vent pipe on the other side of the wall properly goes down to the main drain and also to the upstairs bath and out the roof.
Would an AAV help? It looks like there would barely be enough room to install one between the trap and the wall.
