Running an airline will push the water up because when I had a well drilled , that's how the driller tested the gpm rate. But he was using a huge pump on the back of the rig. Not sure how much air you would need. At least 10.4 psi like Manris said but not sure how much air(cfm).Concept is no different than a small aquarium filter.
