I am located in Florida. I have an irrigation well and when I open the valve for the pipe that is on the top of the well, the water is under pressure.
Pump is mounted on the side and is a surface mounted jet pump. Well is probably less than 25 FT deep.
Why am I seeing water under pressure from the well?
An artesian well brings water up to the surface without pumping. This is because the water in the underground reservoir is under pressure because it has water in the water-bearing layer at a higher altitude, and is not able to escape before you drill down into the layer. These are encountered in many areas of the world.
