Hi, all, I have a sand point well that was driven about 6 months ago.This is used for sink/bathroom at a hunting club. Its down in the stream 34'. I had some trouble after it was driven with a suction leak............I coudln't keep prime more than a day. I endened up welding ALL the drive couplings and that worked and I was able to keep prime. Last week it was used for a week straight. Duing this time, I has two times that the system lost prime............both on the same day. We turned the power off at the pump and restarted it, and both times, the pump reprimed itself. Has anyone ever had to do this, and what causes it? Thanks Jeff
