View Full Version : Rainbird 5000 Rotor Nozzle Selection

I'm not an irrigation professional... just a homeowner looking for a little advice on my system.

I recently built a new home on o 1 acre. The home included an irrigation system installed by my builder's designated irrigation sub. For the most part, I think the system is adequate, but one thing that they did that doesn't make sense, is they installed the #3 nozzles on all of the rotor heads regardless of the arc pattern of the head. If my zones were laid out by arc pattern, I can understand how this could be workable by adjusting run times, but I have zones that are a mixture of arc patterns. For example, one zone has 2 full circles, 2 half circles, and 1 quarter circle. Why would I have the same nozzle on all of these heads?

The first thing I tried was the 30' MPR nozzles. I installed the F(ull), H(alf), and Q(uarter) nozzles accordingly, but it appears that the precip rate of the MPR nozzles is too high for what appears to be marginal pressure. The 30' full nozzles were only throwing about 22'. I hooked up a pressure guage to one of the head outlets and was reading about 30 psi when the zone was running.

My next plan is to go back to the standard blue nozzles which can have a lower precip rate, but selecting the nozzle #'s based on arc pattern. What would be a good starting point for nozzles for a mixed arc zone? My plan was to try the 1.5, 3, and 6 nozzles on the quarter, half, and full arcs respectively. Does that stand a chance of getting something workable as far as precip rate and throw distance?

Any advice is appreciated. I apologize in advance for being a homeowner meddling in the art/science (Which is it?) of irrigation, but I think I have a better chance of getting it the way I want it than trying to explain it and getting it implemented by my builder's selected irrigation contractor.

Thats what you want to do provided you have the correct gpm supply.

It very well could be you are overzoned. Try the blue nozzles, is there a way you can
measure the pressure while the zones are running?

RCDuck
08-01-2008, 03:29 PM
Excuse my ignorance, but by overzoned to you mean too many heads on each zone?

As I stated above, I did install a pressure guage in place of one head on the zone and measured 30 psi while the zone was running, but I guess that probably isn't completely accurate since there was one less head operating on the zone than there is when the head is in place instead of the pressure guage.

Yes, I wonder if the system ever worked properly; most of us have not had
good luck with builders because they're usually out of money when it's
our turn. At 30' spacing, how many heads do you have on each zone?

RCDuck
08-01-2008, 03:53 PM
5 heads max... some zones have 4

Mike Leary

5 heads max... some zones have 4

W, with four heads, MPR "Green" nozzles, you are burning about 10 gallons
per minute. You need at least 35 psi to throw 30. Using the blue nozzles
would cut the gpm in half & getting the pressure up to where it's needed.

RCDuck
08-01-2008, 04:04 PM
I guess that's the conclusion I came to after trying the MPR nozzles. Hopefully the blue nozzles will work for me... they did seem to have adequate coverage with #3's installed in them, they just weren't matched for arc pattern. I do have several zones that are either all halfs or all fulls, so if I need to I can just leave the #3's in them and adjust the run time accordingly.

Mike Leary

The MPR nozzles are cool, but water eaters. Good luck.

Ok Mike, you know in your irrigation SOUL better than that. Boot's could be a slinger who has climbed out of the trenches to Rep level, but he is a mud slinger. No doubt about it. I don't believe you could fake what we do, even in this virtual medium. You either UNDERSTAND what its like because you've been there or your a piker fishing for info and attention.

You know what, I grow weary of this B.S. and I have better things to do with my time. If I had pulled half the crap that Boots has with regard to the flow equations I would have been flamed out of existence, with Boots leading the charge. At least when I am asked to produce supporting documentation I provide it, Boots on the other hand does not.

Yet somehow Boots, playing his childish word games and continued avoidance of posting something useful, gets bailed out once again by MD. What happens as a result? You all make me out to be the dumb azz piker. For some reason having an extensive education and 15 years experience is not enough around these parts. No, I may not be 100% irrigation, but I will be the one laughing last when the landscape irrigation industry comes to a screaming halt due to water shortages.

So in closing .... you all can KMA. :waving:

If it is not a simple mathematical equation without using additional data, assumptions, or charts I am not interested.

The fact that your solution did not use the dynamic pressures given to you in the problem only demonstrates you picked a flow and solved for a dynamic pressure, which I might add, is obviously not the correct way to solve the problem presented to you.

LOL about the changer. Billy was no slacker, but Cozy had a way of tuning
his drums that gave them that "tubby" sound, that none of us ever achieved.
