Bathroom venting

Having read and contributed to a couple recent threads about horrible odors in the bathroom, and noting that I closed off the vent alongside the sink which completely eliminated the odor for me (yes, I'll replace the vent when I have the chance, I'm in tiny town CO now) I am wondering:

Is it possible that the vent is actually connected to the black tank, even as it is intended primarily to prevent sucking the water out of the P trap under the sink?

I ask, because the stench was horrible. Raw sewage smell. I just find it hard to believe that the silky white water that comes out of the grey tank could smell like that. All it is, is shower water and hand-washing water. I haven't gone on the roof to count vent stacks, but I just wonder if the manufacturers might be connecting the venting together somehow. It isn't as if the vent by the sink could result in actual water/waste coming in, and if the vent was working properly, there shouldn't be any fumes or problems . . .

Just wondering.

  • believe it or not, grey water can stink - a lot...
    for cheap protection I went to amazon and got this:
    Elemon-nate for the grey and obviously use something for black tank too...

    (and if yours is like ours you have TWO grey tanks to 'lemon up' !)


    and never let your p-traps dry out.... that can do it too !
