Thread: Sump Pump discharge pipe air hole

  1. #1

    Question Sump Pump discharge pipe air hole

    So water is expected to spray out of this hole during the pumping action? Doesn't this decrease the amount of pressure that is applied to the water being pumped?

    Default hole

    It does not diminish it to any signicant degree, but not having the hole will cause more serious problems.
