Choose full-circle nozzle instead of adjustable Adjustable = 45° to 270°. Full Circle = 360°
No head to head coverage Ensure nozzles have head to head coverage
Stem gets stuck in up position
Debris is stuck along stem & cap
Hold spray down for a minute while water is on
Untwist the cap and rinse o debris
Stem does not pop up all the
way

Insucient water ow Reduce number of sprays per zone
Brown spots - grass not getting
water
Increase zone run time. Rotary nozzles apply water much slower than a traditional spray.

Rotation speed is not equal
among nozzles
There is some natural variation between
nozzles
Leave alone; water ow is equal though rotation speed may vary
