I have a bathroom in the basement. About ten days ago we started smelling an obnoxious odor. Over the past week, I made sure all the traps were functioning and filled. I checked the vent stacks. I replaced the wax ring on the toidy. I still would get the smell. So today, I finally went after the only remaining ingress point in the bathroom; the vent fan.
It's the vent fan. I figured that out, finally, by sealing the fan box with plastic and the smell has not returned.
All I can figure is something got in to the vent and exhaust system and decided to shit/die/eat, whatever. I pulled all of the stuff I could pull given the box is new construction.
Now I'm kind of at a standstill. I could tear into the problem further, but I'm not looking forward to drywall repair, etc.
So, who does one call? Is there a specialty (plumbing, HVAC, whatever) that deals with this type of issue?
****in' varmints...
BTW, I'm also about to shoot me a Flicker that's after my soffit.
