Bottom of the skimmer cup edge. So if you were to shut the air off (valve) you could take the collection cup off and the water would be just below the rim?
That's where mine is sitting now! I almost got mine hooked up and running tonight. Ran into a snag when I realized I never glued a piece of pipe to the T for the output hose to fit on :? Hoping to have her all hooked up and running tomorrow night!
