My Zoeller Sump is pumping into a Y and the bottom of the Y has an end cap with the 3/16" hole pointing (vertically) down at the water. It was installed by the plumber when the house was build. Is this arrangement releaving the "air-lock" possiblity as the pump manufacturer recomends? There is not any noticeable water splash as there would be if the 3/16" hole was higher up in the discharge line.
