HOW THE SUDDEN SAND INFLUX TEST WORKS:
To see if Rain Bird’s internal filter was up to the challenge, we added grit to the lateral line, then flushed water through the system. We watched Rain Bird and competitive sprays for any clogging or pattern disruption.
HOW THE SANDBOX TEST WORKS:
As spray heads pop up and down, they can pull harsh grit into the stem and body, which can cause sprays to stick up. To test the effect of this grit on sprays, we repeatedly popped Rain Bird and competitive sprays up and down in sandy, below-grade conditions. Then, we watched for clogs or pattern disruptions.
To avoid stick-ups, don't install knock-offs.
