There have been comments concerning the fact that the BEST OF series videos were created several yrs. ago yet I have the current year noted in the title. The reason is that the facts haven't changed yet and when they do, I'll be sure to create a new video reflecting the new information. Secondly, to provide current/relevant information, the title must reflect the current year's date in it. Thanks for trusting me to provide current/relevant information for you. 🖖

As a landscaper in California, I try to install rotor spray heads anywhere I can. They are more efficient than regular pop-ups and you don’t have to use that many heads comparatively. I’m trying out the MP-Rotators in my lawn this year and I’m already noticing dry spots and it’s been a very pleasant spring/early summer so far.

I have had MP 1000 Hunters in half my lawn without fail for 8 years. Then I bought RB rotors for the other half but upon seeing your videos I returned them and got more MP 1000’s. My needs were for low flow and the RB precipitation rate is 50% higher than Hunter so mismatch flow in brands. The second reason is the tolerance to weed wacker hits, my gardener edges with a weed wacker and always “cones” above the sprinkler, the exposed RB nozzle design would not stand up to this treatment. Thanks for saving me from a lot of headaches. San Diego.

Great video! I completely agree with you on the MP Rotator. It really IS the best nozzle in the market. However, I would respectfully disagree with you on using the nozzles in shadier of cooler areas. We install MP systems as much as we can here in Los Angeles. We absolutely love them. It’s just one of those things where the contractor, and the however, need to learn about water management and how to calculate irrigation runtimes. We’ve never really had any problems with the nozzles not putting out enough water or the nozzles not being good enough for full sun applications. I would add this though, avoid using MP3000 or MP3500s for lawns. We don’t go any higher than MP2000s for lawn. More heads and more cost but it’s provides a better coverage to ensure everything works good.

I'm a fan of both MP Rotators(I also live 10 minutes away from Nelson's which originally designed and manufactured the MP's before selling the design to Hunter back in '06 or '07). I even still have some of the original MP heads labeled "Walla Walla Sprinkler Co." in my lawn shed that I no longer use. I also like the R-Van's. Both have their pro's and Con's. I like the bigger drops, thicker streams, and higher GPM and precipitation rate of the R-Van's, especially love the tool less adjustability of them. The MP's seem to last longer without something going wrong with them, they also have nozzles that spray up to 35 ft.(in perfect conditions), they seem to be more durable due to having metal adjustment ring around the head, also double pop to clear any sand or debris, and seem to not need readjusted over time like the R-Van's seem to need. I can find R-van's cheaper than MP Rotators currently but I already have enough of each to replace 5 zones I run them in. Currently have the R-Van's installed for a couple of years because find I prefer them over the MP Rotators personally.

Hot weather environments require much deeper dumps of water near edges such as sidewalks so rotors like the PGJ are better suited to areas near cement.

Beyond the intro-bling,… great vid!

This was a very detailed video. I like the fact how these hunter mp 's are so good. and the fact that they will fit on any brand of sprinkler exept toro in my opinion. for example i can use them in rainbird bodies. I look for more to come. another video i would like to see is sizing rotor nozzles for low pressure sysrtems.

I experienced this problem and made the same mistake ,thanks for confirming but I do think if one times it correctly you my end up with a positive result.

Wow .... you described exactly my issues with MP rotators! and here I am thinking it is me, and here you are a pro and can't adjust them well. I feel better now!

Sad to say I really expected more, I use both Rvan and MP rotator, only place that I can find certain MP rotator is from Ewing Irrigation (local/regional company), I find the red/tan color nozzle for the Rvan are spectacular, all the heads overlap by several feet (retrofitted old spray style nozzles, also capped several sprinklers all together, still get amazing results). I’ve got nothing bad to say about either MP or Rvan, granted I’ve only been able to find side strip nozzles in the MP rotator and don’t feel like paying $11 per nozzle, needing 10 nozzles or so to experiment with the Rvan. Also, my HD has dropped several different spray styles from both RainBird and Hunter, no idea why, but it’s harder than before to find these style nozzles locally

Just wanted to say you make some of the very best videos on KZfaq and I've seen thousands

Thanks for the video. About 3 years ago I replaced my Orbit Saturn II rotary with Hunter MP rotators. So far I'm pretty much sold on them. Yes I get dry spots, but I've always had dry spots. I have a kidney shaped yard so it's hard to get even coverage. The Orbits, and I assume all rotary are similar, are horrible in managing coverage due to the way the go to one end then back. Because of this the coverage changes drastically as you change the angles. I wish someone would develop a software program to optimize placement. To bad the Hunter rep couldn't help you with your problem. Looking forward to your newer video mention from recent jobs in June 2024.

8:03 Since the Hunter MP head puts down the water at 1/3 of the rate, did the run time get extended to make sure the grass got the same amount of water?

What a small world! I went to College in Walla Walla for Mechanical Engineering. One of my classes took us on a field trip to Nielson Irrigation to check out their testing facility. It's cool seeing them and the onions brought up! Side note - did you ever make a video on the PGJ as mentioned in the video? Thanks again for your efforts on imparting your knowledge to the rest of us! I have used it well at our first home.

I love the video. I have a 2000 square foot yard with lots of smaller shapes. Largest distance is 12 foot. Currently using 8-14 Rvans on RB 1800 30 psi heads. I have had issues with about 1/3 of my almost 40 nozzles. Either lack of spinning or missing sections of the streams entirely. I notice that they done retract all the way after a few years and they sit on a layer of grass and dirt between bonnet and nozzle. My debate is to switch to regular fixed and variable sprays, or try the MP 800 and 815 line. More flow and has charts for 30 psi. I would put in 45 psi stems where needed to get max range. I tried to be clever I suppose and save water, but 2 different companies told me they don’t bother installing rotator nozzles due to too many call backs. I see why. I installed this system myself and oversized my lines so it should handle the 2.5 times flow that regular sprays put out. Most zones are full sun, I am happy with the water rate on the ones that do work, and have complete arcs and spin. But I have to pull up and flush 6 or so every time and some still are incomplete. I have tried regular stems without prs which will run at 65 psi and no difference. Just wondering if the 0.8 line of MP rotators are well tested, popular and reliable at the 30 psi published numbers and if I should switch a few zones to them, or stick with fixed and van sprays. All my distances range between 6 and 12 feet. Cool season grass on clay with top soil added, south east Michigan. Thanks

5:47 yes and no… the rotating part of the r van is less stiff than the most rotator plus it is built cheaper…I can also see the streams on the r van is not as smooth as the motor rotator

I appreciate this video. I was planning on hydroseeding a 260' long 25' wide 6' tall berm on the back of my property to create a native grassy meadow hill, but I have some limitations: New Mexico high desert (wind, UV, dryness, heat), two 7.5GPM water lines and a 30% slope on the hill. Regular spray heads need more water than I have, so I was considering the MP1000-90s, but your video - and the recommendation against them from the hydroseeder - are making me see that it's a doomed project. I can water a few plants one by one, but spraying the whole area reliably doesn't seem possible with these limitations. Thanks for helping me come to that sad truth.

One major question for rain birds what size particles are actually getting into the sprinkler head with the extremely fine filters attached when buying the heads?

The problem with mp rotator is that sometimes they get stuck. Even after i replace them they get stuck again. I replaced the stuck ones with rvan and works great! So i have mix nozzles

Thanks for the video and the heads up! You just saved me a lot of money and likely issues down the road. I live in the Phoenix Arizona area where we often see temperatures over 110° several months of the year. I was literally just about to submit an order for a bunch of Hunter MP Rotator nozzles. They seem to be top of the line, the best of their kind, and really I just wanted the rotary nozzles for the coolness Factor, so my yard looked like the Bellagio while my sprinklers were on. It seriously looks so cool! But I was a little worried about the fact that they put out so little water because in the desert, if you water too slowly you lose a lot to evaporation before it can actually penetrate. Their MP800 series puts out more water so I was looking at those rather than the 1000 series. I guess I should go back to the boring regular spray nozzles. Boo! 😒

I stumbled upon your video and boy am I glad I did. I’m in the process of adding onto an existing system. I deal with low GPM 7.5 but relatively high Psi 80. So the Hunter MP rotors looked like an excellent choice for my turf lawn. Guess I’ll stick to the Hunter PGJ and go with more zones. Thanks.. The MP rotors sure look good though.

I am a licensed Irrigator from Texas with over 7 golf courses , 2 Championship Sports Fields and 100s of other projects and Hunter MP rotators are crap. Sorry Craig Berlin but these rotators may of been 1st but the RainBird R-Van blows the MP out of the water. The flow throttle on the Bird is the biggest plus but so is the flush out abilty. You may not receive "paid compensation" but you probably get free products. Sorry folks to say this but the Hunters are junk and inferior to the R van.

Hello, Do you think using rotary nozzle is always a better choice than regular ones ?

EXACTLY WHAT I WAS LOOKING FOR! THANK YOU!!!

thank you so much for taking the time...

I’m working on replacing my lawn with drought tolerant landscaping as a part of socal’s turf replacement program, and am required to replace the sprinkler system with either rotating heads, micro spray, or drip. The irrigation timer wouldn’t be on more than once a week, and would be running around 4am, do you think the MP’s will work?

What is the difference between the SRM and PGJ? Is one better than the other?

Does anyone have any real life experience, good or bad, converting a traditional pop up system to all rotators? I understand I may have to add a few heads to ensure coverage. I live on the Eastern Texas border so late summer heat is an issue.

Tom! I’m now on my third vídeo great info and very well done! Thank you

Hey nice vid good detail and info 👌👌

I want to add rotors but I would need 3/4" inlet PGP Ultras to cover the area I want... I use 3 in corners of a lot with MP3000s right now. I simply don't know if adding 3/4" inlet bodies out would not have enough flow since I'm using 1/2" lines currently...

I have the k rain my sprinkler Depot does not sell hunter nozzles love your videos

Thanks for this! My Rachio 3 Smart Controller app is trying to get me to "upgrade" by sell me the K-Rain rotary nozzles "for better sprinkling coverage and more efficient watering" than my standard spray nozzles. And at $22.50 per 3-pack, they aren't cheap! Turns out my existing Rainbird standard spray nozzles are better? Huh!

When they put in the irrigation lines on my property, a few were set in @ 4' from my property line. I need to have rotary sprinkler heads that will reach @ 12' in the front of the head but only 4' in the back. Does any company make a rotary sprinkler that adjust distance as it rotates? Say 180 degrees at 4' and then extending out 12' for the other 180 degrees? Thanks

This may seem odd, but i have a 1,200 square foot putting green that i need to be able to cool down during the summer. Im looking for a head that puts out less water per minute as i want to run it for 20 min or so on hot afternoons to cool the turf but not water deep. I have two zones covering the 1,200 square feet. Im finding that the heads ive tried are simply putting down too much water.

I have a flat, irregularly shaped, small yard (3000 sq ft.) that has rainbird 1800, fixed spray nozzels. I have a lot of dry spots because of the shape of my yard and because several of the sprinkler heads were placed just a little too far from each other for head to head coverage. Several were placed more that 15 ft apart. So I was going to replace the nozzles with either MP rotators or R-Vans because they spay further for better head to head coverage. So you don't think the rotators would be good for relacing the fixed sray heads for my application? I am in the Denver CO area.

You replaced them but at what cost to the homeowner in terms of water use? Doesn't the replacement use more water vs MP rotator?

I may have missed it, but to what do you attribute the failure of the mp rotators in that problematic application? What was it about these nozzles that caused the dry spots? Could it be that the climate in question requires a special design for use of mp rotators? Also, I'm trying out a white clover lawn in southern CA, which will eventually require less frequent but deeper irrigation. And I'll be attempting to conserve water in any way that I can. Do you see these mp rotators problematic for my application as well? Thanks

If i have normal u type Rain bird nozzles , do i need to change the whole set up to use rotary style ? or will just the changing the nozzles work ?

Agrees with my sense also.

I live in a area with a lot of wind. I am looking for rotors that put out larger drops and less aerosolized drops that blow away.

Can you do a video of a hunter I20 vs rain bird 5000

I have the MP3000 rotators about two yrs old, when house was built. I have a few that seem not to rotate very slow or not at all. I made sure filter clean and the body from dirt and still no change. Any ideas or did they just go bad.

I have to replace my mp3500 every 3 months. They always stop spinning. Looking for a different solution now.

Being a Irrigation Technician myself, I tend to stay away Hunter products if possible. I like useing Rain Bird's R-Vans. More water, less run time, Easy to flush the nozzle, no tools needed to adjust and can co-exist with Gear Rotor.

I want to cap off one Irritrol HS series head body(nozzle is MP2000 rotator), where can I buy that cap. I measure the body diameter around 1-5/8". Another is I could not find any screwdriver can adjust that small screw in the head middle. Is there any special tool to use, where can I buy it? Thanks in advance.

I have two parkways that are only about 4 ft. wide. Will the MP side strips work for that? They have a radius of 5", but I'm not sure if you can adjust that downward. Thanks

Thanks for the video. Would standard fixed pop ups, rotating spray nozzles (like this video), or rotor sprays work best if it’s really windy, even at night? Also what is best for a hill? Thanks.

I have a wood deck that keeps getting soaked each time the association sprinkler system gets turned on. The sprinkler service comes out, but to no avail, my deck still getting sprayed. With the cost of our water bills, how costly would it be to replace the sprinkler head?

Where is the video where you describe the issue you had with the MP rotators? The future video you mentioned in this video.

Great video series! I have a question, one of my flower beds in front of my patio is on a small hill. Currently I have fan shape spray heads. This bed gets so saturated that it is flooding the area below it. My sprinkler guy recommended the MP rotator heads instead, but I am skeptical. Do you think that will help with my water issues?

RVANs are so much better than the MPRs and I'm a hunter fan.

Why is it that your video illustrates that a slow rotation is better than a fast one? Orifice size dictates water output (all other things being equal) not rotation speed. A stream of water half as much as another but moving at half the speed will apply exact amount of water to the soil. This is a basic concept that is used with Matched Precip rated nozzles. I have used this kinds of rotary nozzles successfully for many years in over a hundred different projects in the hot, arid desert SW with no problems. Low precip rates are great in heavy or compacted soils or steep grades, for example

I was told my water pressure is too high for MP roters. I have the Hunter MP 3000

Very useful video Thank you for sharing

Very helpful. Thanks

I have a lawn that is 17 x 28, what do you recommend? Are rotary not recommended? Thanks.

Would you recommend the MP rotators for a relatively flat 3/4 lot (that does not have many curves or irregular shapes) in northern Illinois?

Am I able to just buy rainbird body and get the mp rotator heads to put on them?

how to adjust R-VAN -SST from rain bird thanks

What do you recommend for breezy spots? My rainbird 32sa and he van mist way too much and it blows away wasting water. My R Van don’t spray well in close so around the sprinkler is often dry.

Mein MP rotator dreht schon nach der 1. Saison nicht mehr. Gesäubert und in Essig eingelegt bringt nichts. Wechsel zu Rainbird Van.

How do I go to your website. Because I cannot go below as you commented to do. Please respond.

I HATE the tiny volume adjustment screw.

Hunter biased video? The so called test video is conducted by hunter so obviously it's going to be biased to their own product.

What lawn sprinkler head do you recommend for Phoenix AZ

Lowes has these!!

rain bird 1800!

Currently, the Toro PRN is only available in male-threads. That said, it is by far the most efficient rotating nozzle available. Why? Rainbird and Hunter MP have an independently tested 50% and 54.4% DU, as tested by CIT. Toro PRN is tested at 70% by CIT. You CANNOT have high efficiency with a low DU nozzle; it's the upper threshold in any efficiency equation. Toro PRN uses a higher but still acceptable application rate, less ports for more water driving through the ports and a lower, 25 degree trajectory vs. most rotating nozzles at 30 degrees. Toro uses a planetary gear drive so only clean water is recommended.

Wala wala onions sound delicious

I gotta surprised with K rain MP nozzles In the field

Yes is exactly the information I needed. I spent a few thousand dollars upgrading my sprinkler system. The landscaper put in all mp rotors. And my lawn got worse. Now I know why.

man, I just wasted money "upgrading" my MP rotator to the R-VANs. I should have just changed out my system to the rotor sprays.

Król jest tylko jeden MP Rotator firmy Hunter ,

I strongly hesitate to listen to anything declaring one product, "the best on the market." In my understanding, all of these nozzles have different strengths that make them better for certain applications than others. The MP Rotator has a precipitation rate if 0.4 GPM which is incredibly low which probably why this guy had better results on shady lawns in cooler environments. The comparable RVAN nozzles have double the precipitation rate of 0.8 GPM which seems to be more popular with the contractors I have encountered in Utah where I live where it gets very warm and sunny in the summer. The truth is that direct sunlight is going to cause problems for any irrigation system supplying water from above the ground. I recently had some conversations with an architectural engineer in my company who told me that nothing on the market has ever been found to be very successful in places like Las Vegas. The approach gaining traction in Las Vegas currently is using below the surface drip irrigation lines across an entire lawn. This does not suffer from evapotranspiration from the sun and is the best, most direct way of getting water to where the grass needs it.

I disagree, Have been using MPs from Arizona - Florida to Hawaii. You cannot beat the low infiltration rates of these heads. Furthermore, with the 3500s you can replace most rotors. you just need to design for head to head plus. Most irrigation retrofits are dealing with low pressure issues due to poor design, these will allow you to combat that. I try not to be a fan-boy but between MP Rotators and SPYK microjets - they are all I use. DO NOT Use PGjs or PGPs - unless you have a park or golf course with ample pressure.

Are they available in India? Where?

22 feet is an awkward distance, I guess you're probably using the MP3000 because the MP2000 is 21 feet at 40-55psi! if a MP rotator's radiues is reduced by the top screw that will produces a great nonuniformity. Therefore, when using MP, it is necessary to use pressure adjustment and reduce the radiues without screws as much as possible. Even throwing 21 feet with the MP2000 is far better than the MP3000.

There is a Coke ad that shows how Coke’s taste is far superior to Pepsi. However, soda drinks are bad for you, drink water!

R Van's 1724 are way more reliable than MP rotators I have been installing and maintaining irrigation systems for the last 12 years MP rotators fail constantly and get clogged up.

MP rotator just needs to push out more water.

OK, when it comes to MP Rotors, LISTEN to this guy! I'm in North Central Texas and last year built a new house. The irrigation guy installed all MP rotors on my 2 acre lot. FAIL! First of all, they seem to ALL stop rotating at some time or another, so it's fun going out and getting sprayed while you twist them to get them going again. Second of all, they spray water in tiny streams up into the air where, in a hot (95° to 105°F) dry climate most of the water evaporates (even at night) before it hits the ground. The water drops are so small and light that what water actually does get to the grass it seems to land on the grass leaves and not penetrate to the ground, hence, it evaporates with huge dry spots left. You need water WEIGHT (large drops) that will hit the grass and penetrate to the ground where it will soak in. It's the GROUND that needs to be watered, NOT the grass... I'm a Hunter guy - all my homes have had Hunter controllers, rotors, and other nozzles, and this house is no exception. It's going to be a hassle replacing the 50 or 60 MP rotors, but I'll have to have it done at great expense.

Mp's are the best. We only use rain bird heads but we don't use the r vans. Only mp. To many problems with hunter heads. Unless it's i25s or the stainless i20.

No one makes high pressure lines so this test is void.

Why do you have Nozzles for 2024 when the videos shows that it was uploaded 2 years ago. SMH!

Hunter is the best by far compared to rainbird

0:16 model more like BRAND… how can we use one model when the arc and or radius is not correct

This is just hunters product video so this doesn't show anything because hunter would of course say that their nozzle is the best one 😂

You'd have to run these nozzles for at least an hour

Hunter extreme bias. If you’re pushing 100 PSI to a zone with a single head, you should be fired.

So MPs ain't good for lawns got it. Save yall time.

that is advertisement :)

Why are you recycling your video. 2024? This is a 3 year old video. Where is the trust???

Я не очень политический человек, но я думаю, что то, что сейчас происходит в мире, очень серьезно, и нам всем нужно более критично относиться к новостям, которые мы читаем, и видео, которые мы смотрим. Мы должны проверять источники на предмет фальши, искать истинные мотивы, стоящие за новостями, и не поддаваться пропаганде. Ситуация сейчас гораздо опаснее, чем кажется на первый взгляд, и мы должны быть объективны в своих оценках различных источников.

Its obvious who paid the video! R-VANs are just way better though!

Please Mr. I would be much grateful it you can help me out on a project I’m undertaking. Please help me out to contact you personally…….
