I have an odor of what seems to be sewer gas coming from under the sink in the rear half bath. The rear toilet is not vented outside as far as I can see. Is that a check valve at the top of a pipe behind the P-trap? I can see a spring inside of it through what appear to be vent holes.
There were some postings a while back concerning a similar issue, I think (that is dangerous, me thinking).

Thanks for the responses. I just unscrewed the "Studor" type vent. I do not know what I am looking at. I can see the spring and the rubber diaphragm at the base of the spring. How do I know if the vent is bad, aside from the odor?

Clean the end of it and you should be able to suck air through it and you shouldNOT be able to blow air through it.If you can blow air at all it is bad and will letgas through.
In a different brand of trailer, my brother in law took the studor cap off put aregular pvc cap back on and had no touble and the odor finally went away. Just sayin

If I recall on your floor plan the half bath is next to the refrigerator. the vent pipe could be running behind the fridge and vented under the fridge vent cover on the roof. One of my grey tanks is vented that way.
