I set up my sprinklers so that I can run 3 rainbirds on one of my stations. It runs great when I turn the manual bleed valve. But, if I run the automatic sprinkler/solenoid valve, then I only have enough pressure to run 2 rainbirds... and they seem to be a little low pressure. What's the deal? Why do I get so much lower pressure on the automatic system?
They are new solenoids, new controller... but they are manual to automatic conversions.
