I drove a "sand point well" with 1 1/2" pipe. The depth is around 30'. I have a 1/2 hp. pump on it and doesn't produce any water. I hooked up a (I believe it called) Pitcher Pump, where you pump the handle up and down, and it does produce water. Not a heck of a lot, but, it does produce. The pumping action takes a little effort, but, not bad. I do have a check valve on the pipe. So, what's the bad news? Is it salvagable?
