Rotary Nozzles Clogging on Shallow Wells.
A few years ago Rainbird came out with a new type of nozzle called a "rotary nozzle." It is pretty much a combination of a spray and rotor nozzle. It is great for distance ranging from 12 -24 feet, although I do use the 17' to 24' more often because of practical design purposes. Fixed spray heads are great for areas from 4' to 15' and small strip patters. Rotor sprinkler heads are better for areas of 25' to 35' for normal mid-grade rotors.
Rotary nozzles also use less water than spray heads and many rotors because of their lower precipitation rate. So, you have the run them about as long as rotors, but the positive side is that they work great on limited water sources such as wells that produce low volume.
The bad thing about using rotary nozzles on wells is that they do tend to clog easier and quicker than normal rotors or sprays. There is a small detachable screen (similar to a spray head screen) underneath the rotary nozzle than can be easily removed by pulling off. You can rinse the screen out, pop it back on the nozzle and screw the nozzle back on the spray head to test. If it is still clogged you may just have to replace the rotary nozzle because one that debris gets past the screen and in the nozzle it is very hard to remove or flush out completely.
I recommended rotary nozzles if you have a limited water source that is also cleaner water such as city water or reclaim water. Shallow well water usually has too much debris that will cause problems quickly. Spray heads have better, more forgiving screens that save the nozzles more often. So, their are pros& cons the bother. You'll just have to determine what is based for your particular landscape.!
