I am trying to find some information on selecting a pump for my situation. Our property has an old well encased in 24 diameter concrete pipe. It is approximately 10 deep with a water level currently at about 7. We have been using this for drip hose irrigation in a small garden for the past 3 years. We have never pumped all of the water out. The pump is a Utiltech 1/2HP convertible jet pump. Each spring we have needed to turn the flywheel to get the pump running but this year the pump will not hold pressure. I am wondering if this is an appropriate pump for this use and worth repairing or if we should try a submersible pump, irrigation pump or something else. Thanks.
