I recently punched a driven well to 41 feet with 2" galvanized pipe with 5' well point. My water table is at 19'(so 22' in the water). I have a question about pump/pipe sizing. I am going to use a 1hp shallow well pump that is rated at 15gpm. The pump inlet is sized at 1 1/4". Will there be enough suction from the pump if I reduce the 2" pipe to 1 1/4" at ground level? If this won't work, my other idea is to use a 1 1/4" pvc well point placed inside the 2" casing. I am concerned, though, that the draw will exceed the water that is replenished into the 2" pipe. Any thoughts would be appreciated.
