Rain Bird® nozzle sets for the 42SA
Rotor are designed to save water with even and efficient
coverage. Rotors apply different amounts of water depending
on the pattern that they are set to water. A rotor set to
water just 1/4 of a full circle applies more water than a
rotor set to water a full 360º, assuming the nozzles
are the same. Changing nozzles can help even out the amount
of water being sprayed between rotors that are set for different
patterns. This will help maintain a healthier lawn and save
water (see images A-C below for examples).
