Hi Guys, I installed four 36" sand-points and plumbed them all together, equidistant from each other and the pump. Then from the well, I ran 2" irrigation pipe 400 feet to a manifold where I'm attaching garden hoses to run garden sprinklers. I had to locate the well so far away because that's where the water is. Currently I have a 1HP sprinkler pump that is rated for upwards of 33 GPM. No tank. I have a lot of water volume at the manifold but there is not enough pressure to run even one sprinkler. My goal was to be able to run 4 sprinklers at once. What do you guys suggest in order to improve the pressure? Should I be looking at a shallow well pump with a pressure tank instead of an irrigation pump or perhaps a larger pump? Thanks!
