I'm experiencing having a well for the first time. It has a cycle stop valve, which the well installer adjusted to maintain 50 psi from my 1.5hp well pump whenever water is running. The reason for the CSV, as I was told, is to limit the on-off cycling of the well pump to prolong its life. However, in reading about CSVs, it seems that if the water draw from the pump, when less than the pump's capacity, results in the pump working against higher pressure, and therefore the pump draws more amps and works harder, and potentially gets hotter.
So assuming that I've gotten the above info correct, prolonged pump life comes from reducing the number of stop-start cycles. The accumulation of start-stop cycles is worse for pump life than the pump working harder against back pressure from a CSV? Is that right?
Second question is about how much water to draw during irrigation of pastures and yard. It seems to me that running a maximum number of sprinklers at a total flow which just equals the well pump maximum output would stress the pump less than running fewer sprinklers/less volume? Am I right about this?
And, if that is right, how can I go about determining the irrigation flow which will give the longest pump life?
