That was a good, short, informative video, i just realised that they arent big goofy windmills to check the wind direction and had to look it up. thanks.
I have memories of replacing the leather seals of my windpump in the dark so we have household water that night. Removing the pipe from the borehole was not so much fun!
l have a problem on a 200 feet windmill well l pull out the rods and 2"pip and put new cylinder and put it back down in the wll and it pump water but when it pump the water up and back down .
