View Full Version : First MP-Rotator Strips

While out on the detective work from the prior thread I decided to switch out a zone from spray pop-ups to MPR strips... our first ones in the district for the side, left and right MPR strip sprinklers. The grass is about 7' across in the zone. The pictures don't really do justice and I was a little skeptical at first of the coverage. So... being an inquisitive irrigator I went out and stood in the middle of the grass. Didn't take long for the jeans and Redwings to start getting wet.

BTW... The wet sidewalk is from blowing out the PRX bodies through their flush caps before installing the MPR sprinkler nozzles.

I thought you didn't believe in tilting head's :)

These are angled... NOT tilted. Didn't feel like digging them all up. :)

Hmmm...at least when I tilt my heads there is rhyme or reason...you have on tilted down and one tilted up yet the slope is flat and the distance they need to go is the same...wtf?

Uh, oh. Did I make a major mistake by using a level and insuring all my sprinkler bodies (with the MPR's) were level and plumb? I didn't angle any of mine.

Damn, now I gotta go out there and start kicking heads to get 'em to look like a pro installed them :)

We didn't replace the buckets. We just dug up around them, unscrewed the guts and switched out the 570Zs to 570Z-PRXs. :)

Sheesh Ed... Next you'll having me thinking you're a little anal retentive by using a level on them. :laugh:

I didn't do the original install. We only changed out the guts. :)

You say anal like it a bad thing! I prefer OCD rather than anal, thank you! :laugh:

I actually use a clip-on bubble level (OCD) on new installations [when you have the body exposed] and another little bubble level (more OCD) that fits on top for older installations.

LOL......... :laugh:

I get pretty close without any level. :)

I love to inspect work and walk up and put my heel down next to a sprinkler and it sinks in 6" due to lack of compaction around the head and swing joint. Probably one of the leading causes of crappy original sprinkle tilt. Doesn't hurt to have size 13 boots, 6'-6" frame and 250 lbs. into it either. Separates the pros from the wanna-bees.

Rookies.

I can tell perfect height and level by just stepping on a non popped head.

:)

That said, I'll tilt a head if it makes sense to me.

Nah, I typically tilt on extreme slopes, or if your in situation where you want longer throw to one side of the arc than the other.

At $65/hour to straighten them, keep them coming PH :laugh:

So what's you impression of them?

I've now had the chance to use all the various arcs/distances and am quite impressed with them.

I have yet to try out the MP Strips. I am a big fan of the MP Rotator series, unfortunately no one in Miami will use them.

Just started using MP rotors more and more. Not a fan yet but it sure does offer another angle on design.

We are doing some small track type homes. It is a slower moving development, we did 5 this fall and maybe 15 for next year. Now on my first three homes were zoned 6,5,4 and my two with MP's are zoned 2 & 2. I am looking forward to using them on large corner lots (for treelawn use) next year. And used them on another home last week. Mixed the 10's and 30's on what otherwise would have been a two zones (one for sprays and one for rotors)

Do they prefer the faster distribution on conventional sprays? Or is more trying to teach a old dog new tricks?

The statement, teaching an old dog new tricks is partially true. Some of the ol' timers won't give new things a chance, even if the price is right... Others have no idea on what their doing, the blind leading the blind. Most of my customers are big time irrigation contractors who only do large commercial and highway work. They follow the plan the architect made.

I rarely see residential install around here, partially due to my location. I don't know... I just get bummed when there is no variety, no change, and no urge to help save water and/or better your systems in certain circumstances.


I have been on both sides of the counter and loved trying new things that can help my job.

Are all of the com jobs designed already designed or are any design build. If you ever slow up you might want to sit down with some guys that do the design builds and stress to them the flexibility the product offers. I just submitted a drawing today on a library. I am using something like 70 or so sprays and 5 rotors (small job) but by using the mp nozzle I was able to design 4 zones which will save wire, valves, etc. Otherwise it would have been atleast 7-8 with only a 1" poc. December 2nd I am taking my test for the Lee County area. Is the popular website for commercial bidding Dodge or is it something else?

according to my favorite Irrigation supplier in Orlando, hardly anyone in this area knows about the MP Rotators. They only knew of one person who was using them (an employee's uncle) and they were shocked that a joe homeowner came to purchase them.

They wanted to know how I learned about them.

It was from this forum.

We run the whole range on soil texture in this area from almost pure sand (near the rivers) to clay and hard pan (up the hill in citrus country). However, the majority of our soil texture would probably be sandy loam.
