Super Rotor
Awesome rotors! I was dealing with a poorly designed sprinkler system recently. Low pressure and heads spaced too far apart. With the I25 having the dual nozzle design I was able to use a small nozzle at "full open" to get maximum distance. Having the dual nozzle design allows you to run max distance "full open" without sacrificing the rain curtain.
**they include nozzles with the sprinkler head but the smallest nozzle size they include is the "orange" nozzle. See the nozzle/ GPM chart, if you need less flow than the orange, I suggest ordering additional nozzles.

Love em!
One of the primary reasons for my purchase is the built in back flow prevented. Perfect for the slight slope I'm on.

Got one before and loved it. Quality is just great. So, figure that as I need another head, I'd stick with the same thing.

Are all 12 nozzles options included?
Charles on May 23, 2017
BEST ANSWER: No they are not. Only the ones with a * by the color are included. 07, 10, 15, 20 and 25 are included. The others can be bought individually for .68-.69 a piece.
can you buy just the exterior casing?
gallauer h on Feb 20, 2014
BEST ANSWER: Hi Gallauer.

I have bought one hundred of this sprinkler in the last order. But it has not been relevant for me to check if the exterior casing can be bought separately.

I just checked for you at sprinkler warehouse, but couldn't quite find one. You should try the chat support.

HAve a nice weekend.
How are these shipped ea. or by the case?
