Thank you very much. I love hearing from folks that truly understand the impact that the MP's bring to the turf irrigation. All too often I hear from people that say: "Oh those don't work, my grass is all burnt up!!" Which just translates into: "I don't know/understand how they work!" Which I then reply: give me two weeks on the proper watering coverage, length and time and I will have it looking like a million bucks! It truly just boils down to understanding that not all sprinkler designs are the same, and you have to understand Precip / flow rates to dial in a system properly. Thank you for your comment. I hope to hear from you in the future.

FIrst of all let me apologize for the very late response. I somehow missed this comment. Thank you for the compliment. I have been and will most likely forever be a believer in MP Rotators. I wish you the best in your upgrading your system and the golf course. I would love to hear how it's going. Thank you for the comment.

Thanks! We upgraded six heads last week as a trial run… excellent results. I have 30 more that arrived yesterday - ready to go!

Thank you very much. I greatly appreciate it. I am a really a big proponent of the MP's. I have seen big strides in the improvement in my lawn, and have seen massive increases in my root zone depth. Definitely a huge testament to their effectiveness and performance. Best of luck in your efforts to supercharge and fine tune your system and your lawn this year. I am sure that you will be the envy of the entire neighborhood. Thank you for the comment. I hope to hear from you in the future.

My apologies for the extremely late response. It has been an absolutely crazy spring. I have had a TON of renovations and sprinkler renovations and installs that I haven’t had time to put out anything more than my 2024 intro vid. But you are MOST welcome! Glad I could help!!

Leo, thank you very much. Love the MP's, they are my absolute favorite. Best of luck in your installation. Thank you for the comment. I hope to hear from you in the future.

Andy thanks!! I am glad you liked it. The MP Rotators are absolutely the best. The biggest challenge that I have people speaking to me about is that they think that you can run the zones for the same amount of time that their prior nozzle/head runs at a much higher rate. One guy that I convinced him to get them came back and said "My yard is burning up" I responded "Did you double your run time. Like I told you?" He then dropped his head and said "ummmmm.........NO!!" So I pulled out the specs and showed him that the flow rate/min was 3x less than his pop up fan sprays. I did tell him to run it 3 days in a row to get it to revive, then go back to his normal watering. He came back the next week and said "Dude, my yard is SO green, even after I killed it." Then we had the dormancy talk. It amazes me what the misconceptions that people have with watering. Thanks for the comment. I hope to hear more from you in the future.

Thank you. I am glad that you liked it!

You are correct that it is best to use PR spray bodies when using MP's, and the damage usually can occur when you get to 60psi or greater. Unfortunately I don't think that seeing anything over 60 is ever going to be a problem here in my local area, as most days (at least in 2021) I am lucky to get 30-35 psi which is good but not great. And within a few hours it will suddenly drop to 22 psi. (Which is just above basic human urination psi lol) and the heads will barely fully rise and I have to shut the system off due to lack of pressure, and thereby wasting water that can't get to where it needs to go. I do appreciate the insight and I will make sure to include that on a future video. Thank you for the comment.

I have no idea what the pressure was at the bodies, but at my house in Phoenix, I had 70psi at the shutoff. It caused water hammer issues in the house and I had to install arrestors. I had the MP rotators in a system for 8 years without PR bodies and I didn't have a single failure in 8 years, with 30 heads total installed front and back. When I moved to Colorado, I replaced all of the Mini-Paw impact sprinklers with 40psi PR bodies and MP rotators. Honestly, the biggest difference I see is that I have such an easy time adjusting the rotators now, compared to my house in Phoenix. Previously, you could tell they were rotating at different speeds and the ones that rotated fast were the worst to try to keep in adjustment. The distance adjustment was all but worthless in a non PR body. The units installed through the center of the front lawn, I couldn't stop them from wetting the sidewalk and the walkway to the front door. Rather than longevity, I think the biggest selling point of the PR bodies is consistent watering and ease of adjustment across the zones. Also, certain municipalities have enacted regulations that prevent suppliers from selling non PR bodies any more for water conservation.

You think I would need pr bodies if I have a 40psi regulator at the main source?

@@BombproofCraftsman Need? No. You'll get uneven watering though, depending on how many you have in any particular zone. You would probably benefit from 30 PSI bodies. If it's a small area and only a few sprinklers per zone, you might be ok without PRs.

I am sorry to hear that you are having issues. I have not experienced the problems that you are having. I have only had issues with the 3500 series. Haven’t been that impressed so far with those. Thank you for the comment. I hope to hear from you in the future.

Rachel thank you so very much for the subscription. I greatly appreciate it. I hope that the video and any in the future can help you in your lawn care journey. Thank you for the comment. I hope to hear from you in the future.

I was told that mp rotors were not to be used in lawns in direct Sun because the rotors won’t keep up with the demand of moisture that the grass needs

Huh, I have never experienced an issue like that before. Thank you for the heads up.

You are most welcome. Here are the cheapest MP Rotator screens that I can find. The only issue is that to get shipping for free there is a minimum purchase amount. Just an FYI. Here is the link for any MP nozzle screens for everything but the MP3000, and MP3500 series. sprinklersupplystore.com/products/filter-fine-mp2000-white?variant=43673312649&currency=USD&gad=1&gclid=CjwKCAjw2K6lBhBXEiwA5RjtCXreTj73CsxxnE9_Nscw9sgaNUslm-D75qQkTU4Y77hGHKI_kyrB4hoC62cQAvD_BwE Here is the link for just the screens for the MP3000 & MP3500 line: sprinklersupplystore.com/products/filter-coarse-mp3000-lt-green?variant=43673310985&gad=1&gclid=CjwKCAjw2K6lBhBXEiwA5RjtCcgXM_drSsNYc_8E_HlDS7NzYZNJa5Z7e4xID-VGwkTNNJ82dcSibBoC6UQQAvD_BwE I hope that helps. Thank you for the comment. I hope to hear from you in the future.

The MP stands for "Matched Precipitation" meaning that the nozzle puts down the same amount of water in the model's design from the head to the end of the spray pattern. This also goes the same for the other models in the lineup. They all put down right around .37 - .41 of an inch of water in an hour of runtime at the recommended optimal pressure of 40 psi. (that .04 difference in an hour's time is hardly noticeable) Here is a link to the spec sheets on the MP1000 - 3500 lineup: www.hunterindustries.com/node/501. Hopefully this helps. Thank you for the comment. I hope to hear from you in the future.

Miguel. Unfortunately filters are not required on secondary systems, most of the time. But I highly suggest them if you do have secondary. If you are running off a culinary line from your house or some homes have their sprinkler lines running off an additional culinary line (which any culinary lines 99% of the time require a backflow device to prevent "tainted/ contaminated" water from finding it's way back into the drinkable water). If you have culinary then there is no need for filters, because the water is free of the junk in the lines. Thank you for the comment. I hope to hear from you in the future.

Chris, Don't envy me too much. The pressure here is ALL over the place I have had up to 65 main line, and then it drops to 38 main line. (Yes I did check the filters, LOL) the city that I live in is a great place to live, but the city leaders don't think it's a problem. As far as the number of zones, it all depends on total square footage, layout of the lawn, sun exposure to the different areas, PSI, volume, etc. Most irrigation stores can assist in layouts that will work with all of these variables considered. Best of luck in the install of your new system. Thank you for the comment. I hope to hear from you in the future.

Grant, yes they really do well in areas that have almost any degree of slope. With the slower rate of precipitation you can get the right amount of water down with a much lower chance of run off. I have used these since 2011 and in my humble, okay maybe not so humble, opinion they are the best nozzle out there. The one thing that causes problems is that most folks confuse these with other pop up nozzles or they mix and match them on the same zone. (i.e. pop up fan nozzles mixed in with MP's) this is a bad idea, because they both operate under different flow rates, and the one will rob volume and pressure from the others, causing ineffective results. Plus there is the much different time in run times and that can cause frustration and dry spots. Thank you for the comment. I hope to hear from you in the future.

Glad you enjoyed it. Thank you for the comments. I hope to hear from you in the future.

I have secondary water. So that spigot that you see comes right off the first valve manifold for my irrigation, so checking it right there is an easy way to check my main line pressure. I wish that I had enough pressure that I needed a pressure regulator LOL!! Wow sounds like you have got a good setup going, especially if it works well for you!! Thank you for the comment. I hope to hear from you in the future.

My apologies, I had responded earlier to this and it appears as though it did not go through. The jets are staggered, one short, one medium and one long. There are multiple of these as the nozzle rotates through each revolution. This setup allows for a more even distribution of water that allows for the best overall coverage by replicating, in my opinion, the closest thing to a man-made rain shower that allows for better permeation into the soil, rather than blasting the area with a mass of water and then having the soil reach the point of saturation and the further application of water is no longer effective. Thank you for the comment. I hope to hear from you in the future.

The MP Rotators are uniquely designed to do very well with sloping landscapes. This is due to the low application rate which allows the time for soil to absorb the water without over saturating the ground and then results in more runoff. So expect to run them long enough to get down the right amount of water, and this is directly related to the time of the year it is. During the spring and fall when the temps are below 85 degrees you will need to run the system to where you can get down an inch of water a week. (So if you water 2x a week, then you would need to put down .5 of an inch each time, to reach your needs. When the temps in the summer push past 85 degrees consistently then you would need 1.5 inches a week. So again if you water 2x a week, you would need .75 each time or if you go to a 3x a week, then it would be .5 each time to reach 1.5 in.) The version of the MP will be determined on the distance you need to cover and the angle that your needs are. If you need any further info please feel free to reach out. Thank you for the comment, and I apologize for the lengthy explanation. 🤣🤣 I hope to hear from you in the future.

Jay when i mentioned that they can spray 8 -15 ft yes they water in that area from 8-15 feet. (This is dependent upon the amount of pressure that you have, and the size of the supply line feeding the sprinkler" The "throw" can be adjusted 25% up or down given the aforementioned PSI. Hunter industries has the corresponding specs on their website. (Note: make sure that you are looking at the Imperial (feet, psi) versus the metric specs). Thank you for the comment. I hope to hear from you in the future.

Jeff, I just posted the amazon link, to the specifically designed MP Rotator Pressure Gauge that I used in the video. I will admit it is a little spendy. But I have used mine several times, and I use it every year to check my pressure when they turn on the secondary water. Which just happens to be tomorrow!!

Trey, I actually responded to this comment about 5 days ago. It appears as though it did not go through. So I apologize if this is coming to you way later. There are a multitude of reasons as to why your MP's will not turn. 1 - Depending on your type of water supply. If you have culinary (drinkable and treated) water or secondary (untreated and usually rife with debris). If it is secondary, debris can and will clog any filters along the line as well as the screens attached to the nozzles themselves. If any clogging is happening, it will restrict pressure and flow. So check those first. 2 - If it is secondary water, and the debris/grit is heavy, sometimes the grit will cause the nozzle to fail and not spin/turn. 3 - If there is anything impeding your PSI. ( I have seen small pebbles and rocks somehow get into the line) and this will stop the nozzle from turning. 4 - I personally experienced a major "kink" in my funny/swing pipe to the spray body head that was literally cutting off the flow (just like kinking a garden hose) This one is much less likely but not impossible. 5 - Damage caused to the nozzle. I have seen several nozzles damaged by mowers, trimmers and edgers that damage the nozzles (some so minor, you couldn't tell until you really took a good look at it) 6 - It is possible that you could have received a bad nozzle from the factory. I have only seen this 2 times in 1000's of nozzles, so not likely but possible. 7 - If your pressure is TOO high, (usually 60 psi+) it can cause the nozzles to "spin out' which will cause the damage to the components to the point to where they will spin so fast that they will fail and no longer turn. Again these are just a few possible reasons, I am sure that there are more than what I could think of. Thank you for the comment. I hope to hear from you in the future.

@@TheHighlanderLawn get a rainbird rvan instead!

Thank you, but I prefer the MP's instead, I did not care for the R-van's, but I may do a comparison video, thanks for the content idea. Greatly appreciated!!!

@@TheHighlanderLawn mp need to run for an hour per zone. rvan does it in 20!

I apologize for the delayed response. I was out of town for work and then went on vacation upon my return. To your question, yes the system was originally installed with Rain Bird 1800 Spray bodies. One of the great things about Hunter's MP's is they will thread onto almost any pop spray body stem, so they are very versatile to refit a system with MP's. I have found that I am a little more apt to be replacing all of my spray bodies over the course of time with Hunter's Pro Spray bodies as I have come to find that they are built just a little better in my opinion. Thank you for the comment. I hope to hear from you in the future.

Franz, I have regularly used MP3000's and from time to time MP3500's. I must admit that I have had 2 3500's that failed and my first thought was that I must have had some debris pass through my triple filter and even the screens and it collected in the nozzle, thereby causing failure. The 3000's on the other hand have not issued me any problems. Other than my kids whacking the nozzle with a foreign object an it needed to be replaced. LOL. Because I have secondary water I am routinely checking my filters and screens on a monthly basis, and keep a close eye on them because our secondary here is so terrible. If you have secondary this could possibly be the cause of the nozzles failure, if not then there could be a manufacturer's defect. That all being said, I love my MP's and would never use anything else. Sure it is some extra effort to keep them clean and working properly, but it pays out huge dividends in the long run with the superior (in my opinion) performance that they provide. Thank you for the comment. I hope to hear from you in the future.

@@TheHighlanderLawn thx 4 your honest answer :)

Hi Ray, Very correct they are. But when someone like myself has a major reaction when spiders bite them. (i.e. my hand puffed up and I just about had to have it amputated) I don't have much sympathy for them. Luckily I had a great doctor that helped get me to recover with no limiting effects. So I will be continuing to spray for spiders as I am not down to have that happen again. I am sorry that we disagree on this topic. Thank you for the comment. I hope to hear from you in the future.

Sorry for the delayed response. We had a death in the family and I have been "offline" for about 2 weeks. My entire system (starting at the very base level after my Rain Bird valves/per zone) All black poly pipe, (admittedly I am NOT a PVC fan, unless you have unbelievably HIGH water pressure, it is just too rigid and in my opinion not as easy to tap an additional head) Then I have the black funny pipe that then runs to each sprinkler head off the zoned poly. I use Rain Bird 1800 series heads (even though I use Hunter brand MP Rotators) I have found that the Rain Bird 1800's do just as well as a Hunter Pro Series and are, over the expense of the entire system (65 total heads/nozzles) more pocketbook friendly. I have been asked "if you use Rain Bird products (valves/heads/controller) why don't you use Rain Birds version of the "MP Rotators". The answer is simply this: Rain Birds version are okay, but Hunter steals the show with the design/Construction/performance of the MP's. The MP's can be very expensive when you look at installing a new (or retroing an existing system) the cost average PER NOZZLE ranges ($6.50-$9.00 each at a retail sprinkler store) I have a contractors pricing and am able to reduce that down quite a bit. Now if you have "gear driven rotors" (i.e. Rain Bird 32SA or the like) they are not able to attach swap out by simply taking off the nozzle and installing the new MP back on. It would take swapping them out with a "pop-up" head of some type. There are several brands that MP's can simply screw right onto the existing pop up shaft and you are off to the races. Just a QUICK TIP: If you are going to look at doing an reworking of your system, MP's should not be "Mixed" with other nozzle/head types in the same zone. (for example do not mix gear driven rotors/pop up spray fans and MP's in the same zone). The reasoning is that the "flow rates are nowhere near the same if you have a pop up fan that's flow rate is 3x what an MP Rotator is you will either flood/saturate the pop up spray head area to reach the precip rate of the MP OR you will match the rate of the pop up fan and then not run the MP long enough to do it's job and the area the MP is covering will literally dry right up and you'll be saying "I hate these MP's they don't work!! ( I have some very interesting/slightly warm conversations with those that scream "death to MP's" ) but when they look at the specs/flow/precip rates then they see why they hated them SO much. Because they didn't understand HOW to use them. Once that "understanding" happens then I personally believe that there truly is no other type of nozzle to use. If cost is a huge factor for you then I would suggest retroing just ONE Zone, get the correct heads and nozzles for your application (as there are many) and run the zone for the proper amount of time to get the necessary amount of water to your lawn. I am so very sorry for such a lengthy response to a short question. I just felt that a short or vague answer may not paint the best picture for you. If you have any other questions/comments. I would be more than happy to answer them. (I promise next time they will not be anywhere near as long.) Thank you for the question/comment. I hope to hear more from you in the future.

@@TheHighlanderLawn Now thats a thorough and informative answer! Take my subscription!

Thank you Cody. I have been known to be quite apt to give information in "long story form" LOL, but in this case I wanted them to know as much information as I could give them. I appreciate your subscription!! I will hope to be worthy of it!!

@@TheHighlanderLawn ... excellent advice, I am going to be retro-ing my system this summer, glad I stumbled across your video

My zone run times are about 40-45 minutes. The reason for this is that the MP's flow rate is about 25% of the pop ups. And it will require more time to get the proper .5 inch of water down in each zone. To calibrate your system I would suggest using several tuna cans, or the gauged spiked measuring cups that can help you determine how long the zone should run to reach the .5 inch mark.

@@TheHighlanderLawn appreciate the feedback!

@@Adam-yn9nf Traditional sprays usually put out 1.6in/hr of water while traditional MP Rotators put out 0.4in/hr. They do now sell an MP Rotator that puts out 0.8in/hr in case you need balance towards watering within a timing restriction.

Everything in my lawn is 4 inch. I am currently in the process of swapping the originally installed Rain Bird basic heads to All Hunter PRS40 heads (40 psi Pressure Regulated Spray). And 2 islands to PRS30 (30psi) to help dial in my system. Thank you you the comment. I hope to hear from you in the future.

I have looked at the R-Van's and while I do like a lot of what Rain Bird puts out, (I have used their valves, sprinkler bodies, and my controller is currently a Rain Bird ESP-Me with the Wi-Fi Link to my phone to allow control from my RB app, but I have had a few problems with that Link system malfunctioning. I feel as though Rain Bird missed the mark by trying to copy the G.O.A.T. (Greatest Of All Time) in regards to the Hunter MP's, they are hands down the absolute best in the market when it comes to how they are built, the pounding that they can take and most of all how well they perform!! (Yes I have a very strong opinion when it comes to these, Jeremy of The Greener Lawn and I are constantly arguing about them!! I just tell him that the reason he doesn't like them is because "(He) doesn't understand them!!"LOL) I truly believe that if you use these nozzles, that they will outperform any other model on the market!!! I am in the works of getting some deals working with a sprinkler supply company that has awesome deals and we are talking about a discount for those in put in a promo code that's linked to my channel. But that should be put out hopefully in the next 2-3 weeks. Thank you for the comment!! I hope that your system does everything you need it to. I hope to hear from you in the future.

Thank you for taking time to respond. I'll go with your advice and purchase mp rotator. One more question which valves would you recommend and how to regulate pressure (better @ valves or buy individual for every head) . I would like build something solid which going to run trouble free for years. Thanks

I would suggest, dependent on what your specs for your water supply are, (i.e. pressure, filtration, etc.) the Hunter - PGV-101-G - 1'' Globe Valve w/ Flow Control (FPT x FPT) × 4, for the valves. They are a quality build and really are not that much more than their competitors. I would also suggest the Action brand manifolds, as they are solidly built as well and clearly state on the manifold itself "Made in the USA". (Sorry, my patriotic side came out there for a moment.LOL. I am also not a fan of PVC pipe for the running the lines to each zone. I prefer the black Poly pipe, for everything past the main turn on. PVC in my mind is made for "Super High Pressure" , but I also find it extremely too rigid and if cold temps abound, I find more cracked lines from PVC installs than anything else. If I have not had the deal setup with the sprinkler supply company yet, you can find almost everything you need at CheapSprinklers.com. They have the best pricing on MP's, Valves, manifolds, etc. Although I have to say that their prices on poly and funny pipe are higher than they should be. I would probably hit up your local HD, Lowes, Sprinkler Supply shop for poly/funny pipe. The shipping on the pipe is what tends to push it over the top. Best of luck in your quest to dial in your lawn.

@@TheHighlanderLawn Thanks again for suggestions.. You advice is much appreciated

Eugene, I have almost every nozzle of the MP Rotator series in my yard. But as far as MP1000 I have 5 of them. The rest vary to the size of the area that I am applying them to. Thank you for the comment. I hope to hear from you in the future.
