    zero. Well actually somewhat below zero because the spring inside the gauge makes it read zero at normal atmospheric. But then it wouldn’t really matter because there is no water to run it.
    EDIT: Reconsidering, and this is incorrect. It would read zero because, as always, it is indicating the difference between the pressure inside the gauge and the pressure outside the gauge.

    I better shut up now.
