Ill Phrased ! Two sprinklers are on flat ground. Three other sprinklers are down hill from the others by 2 - 3 feet. I don't know if that has anything to do with pressure loss?
I irrigate an acre of lawn from a well and have 15 different station valves with no more than 5 sprinklers per valve. All stations provide good pressure with one exception Three of these sprinklers on this station are below grade by 3 feet. No even sure where to start determining the problem. Yhank to anyone who will listen
