Hi folks,
About two years ago, I installed a sprinkler system comprising of Nelson I20-ADS rotors. Everything works, I have adequate pressure and volume but the arc on these rotors is terrible. Here's the scenario:
On the Nelson rotors, 75% of the water is in 20% of the arc. So, in a 25 foot throw, about 5-10 feet get soaked while the other 10-15 feet is relatively dry. Last year I bought from 7-20 foot nozzles to no avail--they just simply lowered the arc but didn't change the water distribution.
I was surfing the web and ran across Rainbird's advertisement and captured the
following image... this describes my problem exactly! I just don't know what to do next other than pull these things out of the ground.
Any recommendations?
Thanks, Jason
