Depends. Can you recirculate somehow?Im trying to see how this changes for a shallow well jet pump system?
If your shallow well is a driven well point and a suction pump sucks on the top of the driven pipe, I don't see this technique working. If you had a well point but there was a pipe going into the driven pipe that hooked to the suction pump, and you could run water back into the driven pipe, then I could see that working.
