Do-it-yourself well. How to drill a water well.
Using a long and strong cord (cable), a bailer is lowered into the well, reaching the very bottom.
Then raise the instrument half a meter from the bottom surface and sharply lower it. In this case, the ball, jumping up under the influence of water hammer, opens a hole in the bottom of the bailer, through which water mixed with sand and silt enters the pipe. The ball then descends and closes the hole. To fill the bailer more completely, similar movements are repeated three to four times, after which they begin to slowly and smoothly, without jerking, lift the tool upward. The contents of the bailer are poured out and it is lowered back into the well.
The pipe sits in place of the selected soil.
