A neighbor just drilled a new well and put in a submersible pump. He gave me the old single-drop jet system (AO Smith A200EH 1HP motor, Sta-Rite SSJE-1 pump, 40' of 1 1/4" pipe and a foot valve of some kind, Flexcon WWT35 tank), which I would like to use somehow to supply water from the lake to my wife's garden irrigation system. That will consist of a lot of drip emitters and a hose bib. Is this a feasible plan? I've always been a little mystified by the single-drop system. I understand the venturi pronciple and all, but with only one pipe, if the pump is pumping water down the pipe to the jet, how is (more water) getting back up? Time for some Googling, I guess.
