Sprinkler system
I have 9 zones in system with rain bird valves. All valves in first valve box work fine which is 4 zones. The 2nd box I have 5 zones,
I only have half pressure in these valves. The two boxes are connected by 6 inches. I have plenty of pressure from back flow device to valve boxes 55 lbs. No line interference (no roots) plenty of power going to valves from control panel (2
3 zones are pop up with 8 heads and two with 4 gear driven heads. These heads if I hold one up all the way I get the pressure and they start going. I've checked everything possible. What do you think the problem could be??
