How are they performing?

I have some of those. They a comparable to the RB version, but I have not run them side by side either.

we use them. i like them a little better than the RB. Seems a more consistent at the sides of the spray.

By that do you mean less "spitting" out the sides?

Hate 'em. Clog easily, spray pattern gets distorted. I only use fixed spray patterns unless absolutely necessary.

We prob put in 5 a year, only when ab solutely necessary. Would pick RB over Hunter, at least.

Thats my thinking. I use so few that its easier and much cheaper to just stock vans. With the exception od sst , est and cst,s I probably install 30 spray heads all yr.

Have you ever had one of those customers that want one spray head adjusted perfectly and the only way is with the screw setting?
You know the slightest wind, temp, humidity change will alter the spray next time they use it? :hammerhead:

I like it when they call on a Monday saying their heads are way out of adjustment. There's water all over the drive and street.:rolleyes:
You know they watered manually during the weekend and it was breezy at the time.
Show up on a calm day and go through the system with them... all is good but sorry I must bill you.:)

Gregg.. Just curious on what you've decided the answer to you inquiry is after reading all the above posts?

I think a-i misread Hosk's post the exact opposite of what he was trying to say. Hosk only uses 5 vans per year is the way I read it. When I resort to VANs it puts me in a bad mood I don't care whose brand it is.

When Hunter nozzles first came out, the filters ( screens) didnt fit either with an RB nozzle or an RB head ( cant quite remember) So to me it seemed like an inventory PITA. Never took a second look at anything but RB after that.

Yeah - couldn't do an RB nozzle with a Hunter screen. I have a bunch of older non-used Hunter nozzles for sale cheap. maybe I'll post them up later if I can get a count and photo.

Yup, I came to the same conclusion, not worth stocking the extra stuff. What is next .... different thread on the stem? :rolleyes:

Still have some Hunter nozzles floating around that I will use for quick repairs, at least until they are gone.

My biggest issues with RB VANs are:

1. weak edges to the patterns

2. not pathced precip with other heads of the same radii

3. stray streams spitting water in odd directionswhen less than a 180 pattern

4. colored plastic on top not holding up to UV and cracking


Which of these issues has the Hunter product solved?

Biggest issue with the old Hunter adjustables was low tolerance for dirt/ sand particle lodging in the "teeth"...most likely from outside after retracting (not coming up through the filter.)

Second issue was UV degradation, but that was only on fixed risers where the colored plastic was exposed.

Heck, that's all I use is Hunter VAN nozzles on my spray heads.
Install maybe 500 per year.
The newer ones with the serrated edge collar stay in adjustment better, good spray pattern, don't clog easily which is real important with the crappy lake water most systems draw out of, and inventory control is a breeze.

Not to be "Mr. Smart Guy", but I did my time at A&M studid with Dr. Phelps on auditing.
Simple stuff my friend. I can tell you that running around checking heads with a Pitot Tube {gauge} and catch cans that matched percipitation is easy to calc'. I have an honest 15 installs {in TX}with RB vans and never, ever ran into mismatched percipitation using them. Even on various grades.

All I can say is run what ya brung...if it works, great.

We all know over time the spray has huge streaks And sometimes cleaning the nozzle doesn't do it.

I agree. There is no matched precipitation with vans across the arc ... plus there is a rather large mismatch with fixed pattern MPR nozzles .... unless one can expect the nozzles to perform better than what they are spec'd at in the field. :nono:

I don't think you are understanding what I said, or maybe I didn't make myself clear... maybe my typos :-)

What I'm talking about is matched in relation to fixed heads of the same radii. Look at the RB charts.

In other words, if you just want to use them for part of a line where they fit the curvy walkway, the less than 90 deg. corner, or because you don't stock the TT or TQ nozzles.

They don't match up. More GPM with VANs.


If you are only using VANs then it may not be an issue.

Meanwhile, the new Hunters are supposed to match.

unit28
03-21-2009, 11:10 PM
ok, if it works for you, then mucho gracias para particianti.

RB's
Van's are matched to MPR's {stationary}nozzle to nozzle....check
and someone said something about color coding?...done
you said something about TQ's and odd shaped coverage?...suave
Here's the Van's folks step right up and drink the cool aid...I guess.:confused:

This is from RB's site....It's a day old so something may have changed.
Ideal for watering odd-shaped areas.
Blue filter screen (.02" x .02") (shipped with nozzles) maintains precise radius adjustment and prevents clogging.
12, 15, and 18-VAN have matched precipitation rates with Rain Bird MPR nozzles.
NEW! Color-coded on top to enhance your productivity.
Models:

4-VAN - Yellow
6-VAN - Orange
8-VAN - Green
10-VAN - Blue
12-VAN - Brown
15-VAN - Black
18-VAN- Tan

Throw a tic tac on that. check the performance charts, it's all good.:)

DanaMac

I think what one poster was saying is that you do not get MPR when you mix and match VANs and fixed nozzles. A 15' VAN set at a half circle puts out more water than a fixed 15H nozzle. Which will screw up coverage and MPR. No matter if their site says they are the same, they are not.

OK .... checking 10 foot VAN and MPR at 30 PSI (i.e. using a PRS)

http://www.rainbird.com/landscape/products/sprays/chart_10VAN.htm

Nope, not matched precip rate across all the arcs.

10F 2.5 in/hr (square) 2.89 in/hr (tri)
10H 2.8 in/hr (square) 3.23 in/hr (tri)
10Q 2.9 in/hr (square) 3.35 in/hr (tri)


Checking comparable MPR

http://www.rainbird.com/landscape/products/sprays/chart_10MPR.htm

Yup, all acrs are matched precip rate, and are NOT the same as the comparable VAN, not even close.

10F 1.52 in/hr (square) 1.75 in/hr (tri)
10H 1.52 in/hr (square) 1.75 in/hr (tri)
10Q 1.52 in/hr (square) 1.75 in/hr (tri)


In fact, as soon as you go below 12 VAN (4, 6, 8, 10), the precipitation rates across the arcs get progressively worse as the nozzle pattern radius decreases (4 being the worse).

12 VAN and above the rates are matched across the arcs and with the MPR .... so I guess that makes you almost half right per published specs.

Don't know about other people on this board, but once I go above 12' I'm usually looking at using rotators.

you use what you know to make things work ...for you.
As far as being half right/wrong no way. I recommend keeping beds watered seperatly than lawn.
less than 12's and I'm using all 8's which for me goes to beds.
Keep all your side yards watered seperatly too. Throw 8's with 15's, you'll get some very differentiating precips quick.
How could you not?
And as for rotors less than 18' hardly worth it for me. 18 and up gets a rotor for me...Just me though.

---------------
you could also get mismatched precips of other non Van's too.

Matched precipitation rates within 8 FLT nozzles family – higher flow than standard 8 Series MPR nozzles. 8 FLT nozzles should not be mixed with standard 5, 8, 10, 12, & 15 Series MPR nozzles

The specs are what they are. According to them and your statement that VANS have matched precip rates, that means you are right about 43% of the time.

I recommend keeping beds watered seperatly than lawn.

Who doesn't? I recommend you take it one step further and only use sprays/rotors for lawns.

Throw 8's with 15's, you'll get some very differentiating precips quick.

Obviously .... but guess what happens all the time? If I had a nickel for every time I have seen a spray with a 50% or more radius reduction ..... :hammerhead:

And as for rotors less than 18' hardly worth it for me. 18 and up gets a rotor for me...Just me though.

I said rotators, which will give you better overall performance down to 12' radius than a spray any day of the week.
