- Please see my first video on the method used to test these hose-end above ground sprinklers. The goal is to provide some fairly sound information on the performance of these type sprinklers. Your results may vary.
This sprinkler is a masterpiece especially if installed in a 2 acre backyard 😁😎👍
Beautiful
Unfoturnately, you weren't running an optimal combination of pressure/flow. This sprinkler, probably using a 3/16" nozzle, was too much flow for your pump, and produced the poor uniformity. You'd need to retest the sprinkler running at a more optimal 40 - 50 PSI at the head, to get a better distribution because of stream breakup.
The alternatives are to get a smaller nozzle, the standard for 1/2" sprinkler heads usually sold in retail stores is 5/32" nozzle (basically a #10 nozzle) and sometimes you'll see 7/64" nozzle (#7 nozzle) for low flow situations.
tl;dr this particular model/nozzle combo isn't optimal. Retest using a maxipaw head from Home Depot/Lowes etc with the blue #8 nozzle, and you'll see better results because of higher pressure with better stream breakup.
But isn't the diffuser screw intended to breakup the stream for more even coverage at lower pressures? It was all the way out in the test and i believe it would have done better if it was in the stream slightly. It really makes a world of difference with lower pressures to me.
Hoping you can help. I need to put together a metal rainbird system, 45 psi. I need to have a timer that rotates rainbirds. I am wondering what diameter pipe, best place to buy, and what kind of timer. Thank you for your help.
Set up differently, it would be a lot more uniform
