One of my pet peeves is to see properties where contractors install a single row of rotors or sprays that spray from the curb and expect uniformity in watering. There will always be dry spots. See the hardscape overpray in this picture. Further example of the idiocy among irrigation contractors
Another example of a really bad install in Oklahoma. This site has a single row of sprays.
The nozzles are Rain Bird 18 VAN nozzles. The width from curb to fence is 16 feet. What would be your solution? Pressure was measured at 55 psi.
