I've got a commercial property with a 3hp submersible pump. There are 13 zones (all Hunter mist heads) and the pressure is @ 80-90 psi. It looks like the place is on fire when the sprinklers run. I located a couple of the valves and turned the flow control down as a temp fix, but I am thinking this should not be a permanent solution as I had to turn it WAY down. I don't think rotors are an option because it is a long, narrow property-a "curvy" sidewalk with 10' of irrigated area on one side and 4' on the other. I read through some previous threads about excessive pressure, but I'm not sure what would be the best fix for this. I see where Hunter has a valve with a pressure regulator "Accu set"-would replacing all the regular valves with something like this work? As always, thank you for any input.
