what is the inlet size for this sprinkler?
A shopper on Nov 3, 2016
What is the difference between PGP with red nozzles and PGP with blue nozzles?
A shopper on Aug 30, 2015
BEST ANSWER: Hunter red nozzles are the original PGP nozzles. They water best with head to head coverage. All heads do. The blue nozzles were developed to compare to the rain curtain technology of the Rainbird 5000. They help cover better from close range to mid range. They will help if your system does not get head to head coverage. If you have head to head coverage it does not matter which one you use, just break the stream a little.
I turned the adjustment for the radius too far and it is now flushing how do i reset it ?
chill on Jun 11, 2016
BEST ANSWER: NOt sure what you mean by flushing. Read your instructions is really straight forward on how to set the radius or the watering arc.Make sure your start point on the right side of the spray head has the arrow pointed where you want the first spray to hit.. Once that is right your key need to be inserted and rotated to where you want the arc to stop. YOu should be able to figure it out after a few attempts. If not ask one of you friends to help you..
does the product come with a nozzle already installed in each head or do we need to install the nozzle before installation?
Manny C on Mar 24, 2014
BEST ANSWER: They don't come with a nozzle installed you need to pick the nozzle size from the selection provided with your sprinkler head.
How many Hunter sprinklers come in a case?
David H on Jul 27, 2012
BEST ANSWER: 20
Do any of these Hunter heads rotate continuesly?
Bob H on Sep 27, 2011
BEST ANSWER: Yes and no. They rotate 360 degrees, but they will switch directions every 360 degrees, so they don't continuously go around in one direction, but back and forth from 40-360 degrees.
is there any riser that can extend the height of the rotor after it has sunk in the ground a little, or do I have to dig up around the rotor and raise from the bottom?
A shopper on Apr 15, 2014
BEST ANSWER: Depending on your soil, you can take the head off of the riser, remove the existing riser with a tool that has a serrated point on one end and t handle on the other end, install a taller riser. The length of the new riser should be the length of the old riser plus the distance the sprinkler head has sunk into the ground. The sprinkler pop up cannot be extended because it would not sit flush with the ground if it were.
Is the sprinkler head 3/4 inch?
A shopper on Jul 13, 2013
BEST ANSWER: If you are referring to the pipe inlet size, it is 3/4"
how easy is replacement because of leaks?
larry H on May 2, 2012
BEST ANSWER: I am a little concerned about this question. PGPs generally don't leak over their life, All of your PGPs should be in valve zones and the water pressure shuts off to them when the valve closes. If you see residual water draining from the head when a valve is closed, that is just a gravity effect and water is draining out of heads in that zone - don't be alarmed by it. What does happen to them is that the rubberized components on top will deteriorate over time and debris can get to the inside. This causes them to not open/close fully or no longer be adjustable.

I had mine for 10 years, a full set of 19 of them, and I replaced all of them for this reason. You will get a full set of nozzles with each head (buy the full PGP, not just the innards), instructions on how to pre-adjust it, etc. Yes, you will have to dig out around each head you are replacing to unscrew it and put the new one in, just be prepared to get "wet" when you are doing final arc and distance adjustments in open valve zones. I thought it was easy to do, but I did get wet and dirty.

I recommend that you examine the elbow joint next to the head when you remove a head, because this is where PVC piping can be broken easily. You may need to replace some piping in this area too. The telltale signs of a piping leak are mushy spots in the grass near a head and unusually high water bills.

One other word of caution is to make sure a rock or other debris does not get down into the pipe connecting to the new head or it will clog the head. After doing a couple of head replacements, it will become second nature for you.
what radius will the 4 inch adjustable head cover if i have it set to 360 degrees?
Tony T on May 28, 2014
BEST ANSWER: If I understand the question correctly, the radius is independent of the degree of the horizontal rotation. Whether a full or partial rotation, it does not affect the distance (i.e. radius) of the water stream. The radius is affected by water pressure, water volume, nozzle type, whether the nozzle screw is screwed down to partial block the stream, and the angle of the head in the ground.
Does this item come with everything pictured ?
A shopper on Jun 12, 2018
BEST ANSWER: Yes. Everything you see comes with the sprinklers. I have a large yard, almost 1/2 acre and I have been replacing all the old sprinklers with the Hunter PGP Rotor as the old sprinklers quit working. I have now replaced about half of my yard with these sprinklers. Very seldom do I need to replace a Hunter. Some of my Hunters have been in the ground about 9 years. Excellent product and easy to install.
Is this a 3/4 inch inlet head?
A shopper on Apr 6, 2014
BEST ANSWER: Yes, make sure you adjust it as close as possible before you install it.
Does the base of the unit connect to the water line?
Mary D on Jun 21, 2018
BEST ANSWER: Yes it does but you usually use a riser to connect the water line to the sprinkler. The length of the riser is determined to place the sprinkler head level with the ground. The sprinkler then “pops up” above the ground when water pressure is applied.
is this a professional grade sprinkler head?
Jacob K on Mar 26, 2015
BEST ANSWER: I'm not a professional installer, but have owned and maintained the sprinkler system on my home property for over 20 years. The system utilizes these heads and on average I replace one or two every year -- not because they wear out, but because they usually fall victim to being accidentally run over by curb jumpers, hit by the aerator or decapitated by a scalping lawn mower. Of the 40-50 heads installed, I've only had perhaps four or five fail from natural causes during the past 20 years. I find them to be very rugged and, once adjusted, they are essentially maintenance free. Another nice feature...Sprinkler Warehouse keeps them in stock and offers them at a reasonable price. I recommend ordering and keeping a few spares on hand. Hope this helps.
Does this have a 1 inch threaded inlet?
Chuck on Jul 19, 2013
BEST ANSWER: It has a 3/4 inlet and 4 these questions I should be getting paid I'm nt an irrigation consultant
I have received red, blue and gray nozzles with my Hunter PGP heads, is the color of nozzle what determines low angle?
bob i on Jun 17, 2013
BEST ANSWER: Red is the original standard nozzle, blue is the new standard nozzle, and gray is the low angle nozzle that is useful for irrigating under tree branches etc.

Click on the 'Need Help, Product Manuals' on the Sprinkler Warehouse web page. It's in a blue box on the left side about 1/3 the way down the page. The Product Manual page should come up. Click on 'Hunter Rotors'. On the page that comes up you should see PGP Series. Click on 'Product Info under PGP Series and a black and white PDF Rotor PDF brochure should come up. Page 8 shows the performance for each of the nozzles you received.
hunter vs rainbird rotors?
A shopper on Apr 3, 2013
BEST ANSWER: I prefer the Hunter PGP vs. the Rainbird rotor, because I believe the PGP has a better spray pattern which gives better coverage. Also the PGP ultra comes with the low angle nozzles which gives you more options in choosing a nozzle.
Quick question on arc adjustment. So the swinging the nozzle to the right side is the 'stop'/ How do I adjust where this hard stop is? I'm thinking that the entire assembly has to be turned correct?
Nick K on Jun 27, 2012
BEST ANSWER: Nick,
There are 2 ways to adjust the right side, the last one is easier since it doesn't require you to "dig up" the unit. You can see all information about adjusting your PGP-ADJ at the Hunter website and I also copied the section pertinent to your question below:

Aligning the Right (Fixed) Side of Arc

If the right side of the arc is not properly aligned, the results may be a wet walkway or a dry turf area. The right side arc can easily be realigned. One way to realign the right stop is to turn the whole sprinkler body assembly and the fitting below it, left or right to the desired position. This may require temporary removal of the soil around the sprinkler to allow you to grip the sprinkler housing.

Another way to reset the right arc is to unscrew the body cap counterclockwise and remove the internal assembly from the body. Once removed, rotate the nozzle turret to the right stop, screw the internal assembly back into the body with the nozzle aligned to the right side of the area you want irrigated. At this point you have realigned the right arc stop, and you can adjust the left arc to an appropriate setting.

Note: It is not necessary to dig up and remove the whole sprinkler to realign the right arc.
Can these heads be used for 1/2 inch or are they only available for 3/4 inch?
Don K on Feb 19, 2011
BEST ANSWER: Don,
These are only made for 3/4" inch risers but you can buy 3/4" X 1/2" combo risers. They will allow you to put the 1/2" end of the riser in your fitting underground and the 3/4" end of the riser in the Hunter head. This works great without having to change your fitting. These combo risers are cut-off risers so that you can adjust for height. They cost around $1. Hope this answer helps you. I have been doing underground irrigation for about 20 years and am extremely familiar with the parts.
My sprinkler head leak when the sprinkler is turn off. Should I replace the sprinkler head?
Franklin S on Jul 25, 2019
BEST ANSWER: Two things, if the head in at the low end of a zone some water may drain out of the heat for a short time. But if water continues to leak from the sprinkler head you have a leaking valve controlling that particular zone. Locate the valve, clean it or replace it. Good luck.
Sprinkle gets stuck in one position!is there a solution?
David B on Aug 13, 2018
BEST ANSWER: You can try to force it with your hand past where it get stuck. The internal parts driven by the water is unable to push it. Either the cogs are skipping or some foreign material has pinned the gears from turning. If it does not go past that point then you should purchase another of the same product. You can unscrew the internal components from the one in ground and exchange the internal components of the new sprinkler head leaving the outer casing as is in the ground.
does this come with the adjustment tool?
Micah W on Jun 13, 2018
BEST ANSWER: Not sure what SW does with less than a case quantity. There are 20 heads to a case, which comes with 2 adjustment tools.
Without trying each nozzle how do you figure out which one to use?
A shopper on Jun 2, 2018
BEST ANSWER: A good starter nozzle are the red ones. They seem to cover a variety of applications. They are also very adjustable as far as spread and distance. Of coarse this is pending on your inlet pressure. But from my experience the reds we the ones to street with. Hope this helps.
How far will it spray?
A shopper on Apr 21, 2017
BEST ANSWER: I run these sprinklers from a bore pump on a remote property here in Queensland Australia. The pump is low pressure running at less than 20PSI. I only use the smallest nozzle and have about 20 running at once and still get about 5metre (17ft) radius. This property runs totally on solar and the sprinklers are set to only come on between 11AM and 1PM daily and only when the battery bank is on float. I have a smart regulator to control this function. Because we get so much sun, the sprinklers run at least an hour each day. The sprinklers are running full 360degree non reversing which is great as all the old sprinklers would fail when trying to reverse. Good Luck from OZ
what nozzel number does the sprinkler come with?
A shopper on Jun 14, 2016
BEST ANSWER: I bought fourteen heads. I got variety of about 2 doz heads which you have to install yourself.
Check with Sprinkler Warehouse you may be able to get them pre-installed.
I have one PGP roter that will not turn at all. It sprays fine. I can move it manually from point to point (it's set for 180 degrees.) but it will not rotate when spraying. Is this a defective head?
Thomas K on May 21, 2016
BEST ANSWER: I've been using this style of rotor for 11 years. Did the rotor initially work and then stopped? Based on what you have written I would say the head is defective or broken and needs to be replaced
Are these sprinkler heads seconds?
Stuart C on Apr 21, 2013
BEST ANSWER: No, they are not seconds. My original system was installed 5 years prior to when we purchased the property in 2004 and over time a few heads wore out or got hit by the snowplow in winter and needed replacing. I connected with sprinkler warehouse and purchased the Hunter heads from them. They work great! I even convinced my neighbor to switch his heads over to the Hunter heads purchased from Sprinkler Warehouse. I personally keep a few new spare heads on hand should one finally ware out. I certainly would recommend others to work with Sprinkler Warehouse.
Best wishes
Gary B.
I have 2 PGP's that leak, is there a seal I can buy or do I have to replace the whole head?
Mario S on Mar 25, 2013
BEST ANSWER: Where is the leak coming from? at the base. If at the base where it is threaded, put some Teflon plumbers tape on the male threads.
how tight should I install the head? Hand tight ok? Is it best to install the entire unit, or just the sleave? The former seems easier.
Scot M on May 13, 2012
BEST ANSWER: It is best to replace the entire unit, as there are parts that wear out from both the sleeve and the outer part. It isn't difficult to do; simply dig around your old unit with a long, narrow shovel until you get to where the unit connects to the piping (i.e. the distance of the old unit...that is, if it was 4 in. then digging will be about 4-6 in.). The unit joins the piping via a elbow fitting, with one end a barb, that fits into the pipe and the other end, the threaded male.....the unit is simply screwed onto the threaded end of this elbow fitting. Once you successfully dig around the old unit and clear the connector/piping from the soil/dirt, the rest is even easier. Simply unscrew the old unit off (i.e. counterclockwise) and screw the new unit on (i.e. clockwise). Be sure not to introduce any soil/dirt into the line nor around the threads. All you need to do is "hand tighten" the new unit. Before putting the soil back, test that there are no leaks and the new unit operates well (i.e. because there won't be any soil surrounding the new unit to stabilize it, you may need to "stabilize" it so that it doesn't lean over). That's it....it's really quite a simple project. One other thing I sometimes run into: IF the elbow fitting, which in my case has a barb at one end and a male thread at the other, is a different size than the rotor you bought (i.e. the diameter of the threaded end could be smaller or larger than the unit you are replacing...some are 1/2" and some are 3/4"), you can simply replace the elbow fitting with the correct one.
This head installed many years ago and I do not have the instruction book. How do I adjust the sweep and distance of the spray?
Barbara S on Jul 14, 2018
BEST ANSWER: You will need the adjustment tool. A white plastic tool with a hex key on one side and a nub on the other. The hex key side is to adjust the spray distance and the nub is to adjust the rotation distance. It came with your purchase of the spray head.
