So I just finished my irrigation install - zones 1 and 2 both use Rainbird 42SA+ rotors. Zone 3 uses 32SA rotors. Both zones 1 and 2 work perfectly. However zone 3 is doing something strange. It looks like water is coming straight up through the arc adjustment screw (opposite side from the nozzle) in 5 of the 6 nozzles. Now my design calls for me to switch the nozzles out from the standard 3.0 down to a 1.0 to get the proper flow and radius which I have not done yet. So my pressure is running pretty low in this zone right now - only about 15psi - but it is still odd that low pressure would cause the flow to come straight up through this arc adjustment screw. Any thoughts or ideas?
Thanks in advance!
