Great Article Peter. Very informative. I was looking for information on driving an irrigation system directly from the borehole and not having a gravity tank. I have been told that I will burn out the pump by doing this. My logic tells me that adding sprinklers in line just adds head to the pump and if that is still in range for the pump it should not be an issue. I sort of got my answer from your project but any additional info would be appreciated. BTW I am in a neighboring suburb. Thanks again.
