RB or Hunter nozzles?

[F6Hawk]

I am using I-20 rotors, and have heard mixed reviews about Hunter's nozzles. Are RB's any better? If so, any particular one? I have some trees with #4-11 blue nozzles on them that I got for free that I can use, if they are the good ones. Are these the "rain surtain" nozzles?

Thanks for your opinion...

[turfman59]

and you think these are going to be interchangeable

[F6Hawk]

and you think these are going to be interchangeableOf course, aren't they? (And that was spoda be "rain Curtain", not rain surtain in my first post above)

[turfman59]

Of course, aren't they? )that would be ah NO

I don't install rainbird heads, so I've never paid close attention to the nozzles.

I will however, take a look to see if they are interchangable.

The rain curtain nozzles are used on the rainbird T-40 or R-50. What these nozzles do is seperate the water coming out of the nozzle for you so you don't have to mess with the adjusting screw. I myself don't like them because they only shoot out about 30'. They are also color coded. 1.5-black 2.0 brown 3.0 grey 4.0 yellow 6.0 green. The nozzles you have are for a different rainbird head.

The same name is also applied to nozzles on the newer Rainbird gear-drive rotors, which are a sort of compromise between the maximum radius and maximum spread nozzles on the old R-50 head.

More to the point, why is this thread even in existence? Is there some specific problem with the existing system? Anything you may have read is irrelevant if your existing system is giving effective coverage.

Anything you may have read is irrelevant if your existing system is giving effective coverage.Because I was wondering if the RB nozzles provide better coverage. THe Hunter ones seem to spray a stream up into the air, with a bit of spray falling in close, but if there is a wind, that gets blown away, and little in-close watering takes place.

[Wet_Boots]

You don't need much water close in, because the area nearest the head is so small, compared to further out. If you watered in a constant wind, you would have designed the system accordingly. Close in watering is a kind of illusion, because of the geometry of a sprinkler head's coverage. Since people are looking for some downward spray from a head, more companies are providing it, even when it not only is not needed, it is a detriment to newly seeded bare soil, because it will wash the seed away. Since you haven't said that parts of your lawn are dying, I will assume that is not the case, and you can leave the heads alone.

[F6Hawk]

Well, since the indomitable WB said to, I will leave well enough alone! :)

And since I started this thread, the blue RB nozzles will NOT fin into an I-20. They are about 1-2mm too large to fit. Go figure...

I AM having a problem with brown grass, as outlined here: http://www.lawnsite.com/showthread.php?t=117387

But so far, have not been able to correctly diagnose the problem. I have treated for mole crickets twice now, last time about 8 days ago, so perhaps it will just take time to get the grass green again. But this problem has nothing to do with the sprinklers, it is all over the bermuda lawn.

Tanx!

I think one of the first Hunter imitators (Nelson) made a point of the close-in coverage of their nozzles, and I think it may be enough of a selling point that Hunter decided to include it in their nozzles, whether or not it's really needed. I like the downward spray of the new nozzles when I have a head on a riser, but otherwise, I think it's just there for looks.
