I'm just setting it up, & can't even get it to move water ??

It takes a while for the pumps to draw the liquid completely the first time. just hold the red button next to the pump until you see the liquid coming out the end.

Search the forum I linked above. All the answers are there.

I'm pumping up about 3'6" & it's delivering 43ml P/Min on pump 1, about 41 on pump two. So that's very close to 70% .

Lastlight, did you say before that you didn't require check valves at the top?

Nevermind... Nevermind. I got it. Automation is the friend of a lazy person. Thanks guys.

I had to fill about 6 or 7 feet of line before it reaches the tank. Might have to hold the button for a minute or more. Remember to calibrate. The included instructions are short but the unit is very simple and quick to get going.
