Nancy: Ifthere is a leak any where in the suction line, the pump will
have a very difficult time trying to lift water out of your well.
If the jet is plugged, it will
not deliver the water thru the venturi and self priming will be impossible.
The foot valve keeps the water from draining back into the well at the end of the run cycle.
Get a vacuum gage and put it in the suction line…if it dances wildly, you are sucking air from
somewhere. If the guage reads a steady 20-25″, and little or no water is produced..something is wrong with the well.
