I switched to r-van nozzles about 2 months ago. Since then my tall fescue/kbg lawn has flourished. Head to head coverage and no more dry spots. 1" of irrigation a week, you must audit your irrigation cycle. Lastly, I'm mowing at 4" 2x a week. Best lawn on the block.
Do you still feel that the U Series nozzle should not be used in the initial design? The Rain Bird marketing material make it seem like a good choice, claiming 30% less water use over standard nozzles.
Keith, Sorry for the delay. I was on 2 trips and am still catching up on things. I don't know what they're basing that claim on because the nozzle still must reach the distance it was designed for just like the std nozzles and then the lower spray port is presumably additional water. To verify, I just looked up the performance charts for the std and U-series and the performance (water usage and distance of spray) is 100% identical. The only thing I can think of that would allow them to say that honestly is if you reduce your run times by 30% when installing the U-series, but then that's not comparing apples with apples. Is there any fine print explaining where they come up with that? To answer your question, I believe that if you design and install your heads at the proper distance from each other so they easily reach each other then there's rarely need for the U's. It doesn't hurt to use them but I don't believe it's necessary either in most cases when done properly. Let me know if you have any other questions.
David, I have a video about well water that addresses that. If you have more questions after watching that, then ask away. Glad you're enjoying the vids! Today I am working on the final video of this series you just watched. I hope to have it up tonight or tomorrow. Stay tuned.
I'm wondering how you get the 8GPM rating for 3/4" sched 40. I looked it up and at normal pressures (20-100PSI), 3/4" sched 40 will give you 23 GPM. What am I missing?

So nice of you!

That's awesome. Wow. 4" grass. Do you have 6" popups?
@@SprinklerPros 4" and the nozzles seems to clear. HOC will be coming down soon now that we have hit cooler fall temps in So. Cal.
Great info! Looking forward to this series. Thanks Tom!
You bet!
Great information. Look forward to the rest of the series.

I hope to have that uploaded within 2 wks. Cross your fingers.
