    I was sat on the toilet at home the other day and my mind started to wander, as it often does.
    The question I was asking myself was, on a MH/RV with a black water tank fitted what stops the smell coming back from the tank into the vehicle ?

    At home there is the U bend with water in it that acts as a trap preventing smells from coming from the waste pipe.
    On a MH fitted with a cassette toilet there is the Sliding valve thingy.

    This may be obvious to many people, but not to me.
    Please help put my troubled mind at rest. :notworthy2:

    Oh that's easy. The rich and privileged people who can afford vans with black tanks have DNA which only passes sweetly scented pooh :rofl::rofl:

    A sliding valve thingy and a breather pipe for the black tank that exits on the roof.
    The kids say that is how Father Christmas gets in. :)

    Do we really want to know? Isn't it better some things remain a mystery, otherwise what have future generations got to look forward to discovering?

    And no, I am not sitting on the Throne to dream up that bit of philosophy. Perhaps I should be? * :)

    Which offers wonderful views of the declining steel and chemical industries. :(

    To return to original question, we have a black tank with a macerator (just to make it even more thought provoking), the macerator forms a restriction above which we retain the equivalent of a U bend full of water

    Our problem is however still real, despite being told by many of the wise ones on here that mine must vent to the roof area, in my early days I felt obliged to believe them all but still couldn't find a vent, now know they were wrong all along o_O and mine does vent down to the floor, which in turn leads to whiffs back inside :(

    Mine is a marine toilet & it has only the rubber seal on the slid valve to prevent smells returning.This is aided by water laying above the slide valve once flushed.
    There is no vent pipe-
