Ghl doser?

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?
