    Vent on Waste Water Line
    Our house is filling up with sewer gas. I suspect two causes:
    1. Drain trap in the unused bathroom has dried out and is letting waste line smells in, or
    2. Waste water vent that runs through the roof is somehow clogged.

    A. I know how to solve (1).
    B. What's the best way to check/clear any clogs in waste water vent line?

    Anyone know? Thanks for your help.

    First check out what is the real cause.
    With 1 that is very easy : just a liter water "down the drain" should stop that problem.

    Also check if the main sewerage pipe is not slightly or partly blocked. Use one of the in-line inspection holes.

    To check if the vent pipe is blocked : listen at the pipe vent on top, while someone else flushes the toilet.
    It must be very easy and clear to hear the toilet flushing.

    Success!
