Hunter I-90

I'm using the Hunter I-90s to irrigate a food plot for whitetail deer. I'm having a problem with a head not reversing when it hits the limit of its arc to the right. I've flushed it out and they look clean. It just doesn't come back to the left.

I would contact the supplier, or Hunter. Myself, laying out a system for that purpose, would probably be using full-circle impact heads, and avoiding reversing-mechanism problems.

That would be nice but I've got to cover the corners somehow. I will give Hunter a call. The Hunter heads were expensive and I'm not happy with the performance, what alternatives are there for the I-90 from other manufacturers? These heads seem to leak a lot of water around the head and that has caused a bit of erosion around the bases of the standpipe. The heads no longer retract and now the problems with reversing. One year in service and after running once every three days they are wore out. Let's see... each head has only run 122 times and has cycled 730,000 gallons of water.

What kind of water are you pumping through those bad boys? Filter?

It is unfiltered but here is info about the well and how things work.

The well was put in place to supply the water demand for a oil/gas drilling rig. The exploration outfit left it in place and I had the outfit that drilled it set it up for this irrigation need. It has a 5-HP submerged pump and flows straight from the ground to the heads. Prior to the heads operating, it flows into a lake for an hour. I get very little sand at the heads, I could probably count the grains remain in a head when I take it apart.

An irrigation outfit installed this system and it is a first class layout but they won't work with anything but Hunter. It was my understanding that the I-90 head was made for this type of work or the way it was explained to me by my installers supplier that the I-90 is intended for this use. That supplier gave an example of that head typically being used on golf courses, using water from rain water recovery ponds.

Anyway, I'm just trying to get some ideas about what's wrong with these heads and alternatives before I bring my irrigation contractor out here and have to hear Hunter this and Hunter that.

Hey, if the heads failed, they failed. They're under warranty, so get replacements. As long as you have clean water at sufficient pressure, you've done all you can.

In any event, you can probably replace a part-circle I-90 with an agricultural impact head.

True!

I like the looks of that Rainbird head... that style is what I had in mind to use when I started this project but the guy I used only deals with Hunter. Time to check out the warranty and then will report back.
