Hunter PGP ULTRA Rotor

The PGP Ultra takes the foundation of the best-selling PGP Rotor and raises the bar with a variety of new features developed over three decades of research, customer feedback, and lab testing. Among the most notable improvements of the PGP Ultra is its non-strippable drive and automatic arc return. These two features work to allow the turret to be turned without causing damage, and return the turret to its original arc regardless of where it is turned. Other advanced features include 34 nozzle options with several radius choices, and a headed slot and set screw. The diversity of the PGP Ultra offers system installers an array of efficient options on any site.

Great improvement over the old Hunter PGP nozzles
Awesome improvement over the old one. Easier to set up, change nozzles, good selection of nozzles so very flexible for your application. Immediately bought 4 more after I tried my first one. Don't waste your money buying the old style!

Wonderful Product
Was recommended to Sprinkler Warehouse from a friend that was pleased with their products. I needed several replacement heads for our underground system. I found our Hunter heads right away. Once I received the package I installed all three heads and was impressed with the product and cost. I have recommended Sprinkler Warehouse to my neighbors.

Sudhakar G on Apr 3, 2013
I have PGP heads in my lawn already that are about 5 years old. All of them are starting to leak on top where they screw in to the lower case. Is this caused by age and will these new ultras give me better service on the seal between the head and the case it fits into???

Are the nozzles that fit the Hunter PGP the same as for the PGP Ultra? Are they interchangeable?
A shopper on Sep 8, 2014
Sprinkler Nozzels: Have used all the nozzels provided but I have an issue that it does not water the inner radius. Essentially I have a stream that waters about 20' out from the sprinkler head and covers approimately 5' swath. Can you provide advise on how to "disperse" the water so I also water effectively within the inner radius (from 0' to 15 feet)?
Fred W on Aug 28, 2012
BEST ANSWER: I use an un-authorized method when I have that problem. But before you try it turn the screw that holds the nozzle in a bit so it fans out the spray but still keeps the distance. That works 75% of the time. When It doesn't, I drill a small 1/16 to 1/8 hole to water the inner band. Sometimes I drill two holes at different angles to get all the spots. Remember that the extra holes will drop the pressure and you might have to switch to a smaller nozzle size in order to keep the pressure up enough to reach that 20 foot radius. I ordered extra nozzles so I could experiment with different hole sizes.
I cannot set the degree of travel I want using the +/- screw. What am I doing wrong?
Don S on Jun 4, 2013
BEST ANSWER: i use this spray rotor on my lawn so know it pretty well.

use the white plastic key to pull up the head. it inserts into the hole in top and locks in place so that it acts as a handle to pull up the rotor part. You will notice that the rotor can rotate to the left and to the right.

the right stop is fixed if I remember correctly. the leftr stop is adjustable. so install the head by screwing onto the threaded pipe in the ground. Make sure you do not let dirt fall into the line.. you will have a hard time cleaning the system. once you have handtighted the rotor housing, turn the housing so that the right stop is where you want the head to spray. you will have to use your best guess as you tighten since you will be looking at the arrow on top of the rotor. have it point to the edge of the spray coverage. then turn the rotor left. the factory presets the rotor at 180 degrees. you may want more or less. so once your have filled the hole and set the rotor, turn on the sprinkler and observe the actual spray arc. then take that plastic key and insert the tab into the + - hole. if you want to increase the arc turn the key towards the + and if you want to reduce the arc turn towards the -. I find that it works best when the rotor has been manually turned to the stop and then back off a bit and then turn the adjustment. 1/4 turn will move the arc about 4 feet or so. then twist the rotor to the opposite end and then back halfway and let the water pressure move the rotor to the new stop setting. adjust as necessary.
do you have the PGP ultra 04 with check valves?
A shopper on May 25, 2012
BEST ANSWER: I didn’t get the PGP ultra 04 with check valves. Sorry I can't help you.
Does the Hunter Ultra PGP-04 4 in. Pop-Up Adjustable Arc Rotor include the insert nozzels and adjustment tool?
A shopper on Jul 8, 2016
BEST ANSWER: Yes it does. Each comes with a full set of regular nozzles and low angle nozzles. And an adjustment tool..
Does hunter make this item in a 1/2 female version or is there a comparable product made by hunter that is adjusted the same way and has the options for the nozzles?
A shopper on May 27, 2013
BEST ANSWER: There's a Hunter swing joint that's 3/4" male on one end and 1/2" male on the other. The 3/4" side goes into the PGP-04 and the 1/2" end into the pipe fitting. Part number is SJ-7512. Be aware t's 12" long. When I installed my PGP-04's I just cut the existing 1/2' fittings and replaced them with 3/4" T's. FYI, every PGP-04 I installed also got a Hunter swing joint - made it easier for me to adjust them how I wanted. I'm just a homeowner doing this the first time and this setup worked well for me.
What is the difference between Hunter PGP and PGP Ultra?
A shopper on May 5, 2017
BEST ANSWER: w w w dot hunterindustries dot com/irrigation-product/rotors/pgp-ultra

Several differences. The one I noticed the most is that the ultra has more spray pattern nozzle options compared to the PGP.
I have a PGP that stop swinging the arc it is set for, is there a cure or do I replace it?
DAVID N on Jun 8, 2015
BEST ANSWER: That happened once fore, I just re adjusted it, I have nothing but these hunter head in my yard for the past three years and have only had replace three, and that was me and my lawn mowers fault. Good luck
Does this sprinkler head have check valve in it?
David S on Aug 24, 2014
BEST ANSWER: Not really. When water pressure is removed from the nozzle, the nozzle retracts into the housing, This acts like a check valve without actually being one.
How can you tell if you have the PGP ultra or PGP standard rotors ?
A shopper on Sep 2, 2012
BEST ANSWER: Look at the rubber cap on top of the rotor. It will say "Ultra". Also, with the Ultra model, the radius adjustment is slotted so you can use a regular screwdriver.
does this sprinkler non stop 360?
freddy p on Apr 12, 2012
BEST ANSWER: I'm holding one right now and can confirm that once you adjust the screw all the way until it stops on the + direction that the rotor no longer stops and reverses but instead continuously travels 360. Pretty cool! What used to be two different rotor part numbers is now just one.
Does tool and nozzles come with it?
Joshua G on Apr 6, 2018
BEST ANSWER: Its been over a year since I bought it and my memory could fail me but I'm pretty sure that the nozzles are separate as is the tool. I will tell you this though, once you do business with Sprinkler Warehouse and buy decent quality stuff you will never consider returning to Home Depot, Lowes, etc. For not much difference in price you will get a product that works and lasts.
Are these ultra models any better for low water pressure? I typically have about 30-35 psi. Neighbors have about the same. Sometimes the PGPs wont even pop up all the way. If they do, sometimes they may only squirt about 5 feet. I put no larger than the 2 gpm nozzle.
James G on Jul 12, 2016
BEST ANSWER: First, you have a water flow problem more than pressure. They will work with 30 psi, just not well. How many heads per zone? What's the supply size? Likely can only run 3 heads MAX on a psi that low. And that's with 1.5-2 gpm nozzles tops. Address the flow issue with a larger house meter, or severely reduce the number of heads.
What is the difference in sprinkler heads between the Hunter PGP and the Hunter Ultra PGP?
A shopper on Dec 31, 2015
BEST ANSWER: I have replaced around 30 heads last year using the ultra heads. So much better. They are built all around much better. We own a 3 acre bed and breakfast and depend on them working. Definitely go with the ultra.
does this come with 1.5 nozzels?
A shopper on Sep 14, 2015
BEST ANSWER: Yes they do at Home Depot, but I replaced so many sprinkler heads this year I ended up purchasing a couple at Home Depot, but I'm sure Sprinkler Warehouse has the same
how do you adjust this sprinkler?
Rick J on Jun 10, 2014
BEST ANSWER: It comes with a little adjusting tool and you set one margin by twisting the sprinkler and then set the other margin (or the degrees of the arc) with the key...
What regular PGP nozzle is equivilant to a ultra nozzle set ?
Louis S on Nov 3, 2013
BEST ANSWER: Go to the Hunter website and you will find their data on every nozzle they make at several different pressures. But they will also tell you that the ultra gives better (more uniform) coverage. I don't know how much is true but they seem to work alright. Keep in mind that not all the nozzles made fit all their rotors. If you buy many rotors you usually end up with more nozzles then you know what to do with. Good luck.
Where is the check valve located as I do not see a picture to determine if I should buy the rotor with or without a check valve?
A shopper on Jun 30, 2013
BEST ANSWER: The check valve is located within the rotor head and simply prevents water from draining through the head after the pressure is let off. It's primarily used in sites with big changes in elevation where you don't want water continuing to drain out of the nozzle after the zone valve closes.
Hunter replacement for rain bird pop up sprinkler?
John C on Nov 7, 2016
BEST ANSWER: The Hunter Ultra PGP can replace any rotor sprinkler spaced 14 to 40 ft apart. It is highly tolerant of solids in the water (well water), the nozzles can be replaced to change the arc and volume and the rotor can be adjusted to almost any angle. Note that the bottom inlet is 3/4" not 1/2". Good luck.
how can I adjust this sprinkler to turn at 90 degrees?
A shopper on May 23, 2012
BEST ANSWER: First rotate the nozzle turret counterclockwise to the left stop, or as far to the left as the turret will rotate. Next rotate the nozzle turret clockwise to the right stop or the furthest the turret will rotate. This is the fixed side of the arc and all adjustments must be made with the turret in this position. Hold the turret in this position and use the Hunter tool provided. Insert the plastic end of the tool in the arc adjustment socket. The socket is located on the top of the turret and has two curved arrows indicating + and - for the arc adjustment. Holding the turret all the way to the right turn the tool clockwise to increase the arc (up to 360) or counterclockwise (down to 50). I find it's easiest to adjust while the sprinkler is operating (you get a little wet but its worth it). After each adjustment you can manually turn the turret all the way to the left, then swing it back to the right. This will give you a clear visual on where the rotor will water. I make the adjustments in steps manually 'swinging' the turret left to right after each adjustment until I get the exact arc I want.
which nozzle should i use?
richard b on Apr 3, 2012
BEST ANSWER: I would start with the mid sizes first. Then determine if each rotor is delivering enough water in the time that the zone is on. I usually set my zones for 1/2 hour. Longer makes for too much run off for my lawn. But because some rotors cover a larger area than others ( a large arc rather than a small arc ) I have to go to a larger nozzle for those. Sometimes less water is needed. You could turn down the valve in the rotor. But that could reduce the distance the water is thrown. In that case a smaller nozzle will give you the distance but with less water.
The nozzle hold down screw can be put part way into the water stream to give a wider but shorter stream from that rotor. Be careful not to turn it in too far, it will fall out.
Needless to say if the whole zone is either too wet or too dry you need adjust the run time for that zone.
If you are fast and good you can turn the rotor off from the top. That will keep the rotor extended, making for an easy swap of the nozzle.
Is there a model # on the unit?
A shopper on Feb 20, 2017
BEST ANSWER: Although there are a couple embossed digits - "13" and a patent number - on the sprinkler, no model number can be found anywhere.
Is there any model that offers better control of distance without shooting mist?
ArioY on Aug 6, 2015
BEST ANSWER: The water pressure is too high, this creates misting. You only need 30 psi to run spray heads.40 psi to run rotors.
Looking at the PGP Ultra as a replacement for Rainbird Minipaw (the old spitter type). Is this the correct one, or is there another one?
