I have a pipe driver, its a bit heavier than a post driver. After the sand point has been installed, I am wondering about the hand pump. Should I build a small pump shed to help prevent freezing? There is no electricity at this site, so I cannot put a light bulb or other heat source near the casing. Sometimes we head up there in Jan, Feb, March for snow shoeing or varmint hunting. It would really be nice to have water without thawing snow. Are some of the freeze proof water pumps good? Does anyone have first hand experience? I am wondering if they are good or so-so.
