they are on a Hunter shrub adapter directly on a 4" inch fixed riser. The rotor itself is not opening all the way each time.
I did not expect 4 rotor on a 3/4 inch circuit to be a problem at 50 psi. The farthest rotor is about 50 ft from the valve where the pressure is measured. I don't have the needed fitting to measure the pressure at the rotor right now.
Thanks,
Dave
