Modern hand pumps like Simple Pump or Bison tell us to drill a small 1/8" 3mm hole in the water riser pipe that will allow water to slowly drain back into the well a few feet deep. This works because on these pumps, the working cylinder is all the way at the bottom of the well pushing water up from the bottom. Yes a tiny amount of water leaks out when you pump but it is worth it because it prevents freezing.
