Does anyone know what would cause my heads to blow excessive air on all zones in almost all heads for longer then normal when heads first pop up? Also sometimes the zones will switch and the one that is suppose to start will come up and trickle some water go back down than come back up like normal. Any suggestions or things I can try and change would be very well appreciated? Would nozzel size effect this at all? Thanks
Looking for some advice- I need a controller for 16 zones and I know I want rainbird can I just get this one http://www.sprinklerwarehouse.com/Rain-Bird-Sprinkler-Irrigation-Controller-p/esp-4mei.htm with two of these 6 station Modules http://www.sprinklerwarehouse.com/Rain-Bird-Sprinkler-Timer-Expansion-Module-p/esp-sm6.htm??? Heads PGP or 5004 which last longer? Sandy Soil/iron water Brand Valves? Brand Saddles? Good running 1.5 HP pump for sand point?
