Hunter PGP tips, tools and techniques that make replacing and raising sprinkler heads much easier.

I'VE RECEIVED FEEDBACK FROM HUNTER INDUSTRIES!!!
"Hello Robert
Thank you for your idea submission on Hunter’s Open Innovation site. We welcome ideas from our customers that assist Hunter in delivering innovative products and services to the markets we serve. Your idea for PGP Tools for no-dig sprinkler replacement was reviewed by our Product Team through our Built on Innovation program. It’s a problem that we hear of occasionally from customers. A number of “inventors” have sent us designs for tools to service rotors, however, we just don’t sell that many tools to service our products. What we find is that most technicians and installers utilized standard “channel-lock” pliers to remove rotor caps and/or prevent the body from rotating. While not ideal, it allows them to utilize a single tool for a wide variety of products, including rotors and sprayheads. By the way, well done on your video. Very informative and concise. Our Product Manager mentioned that the Hunter PGP-ADJ riser with blue nozzles should fit in the older PGP-ADJ body that originally had a riser with red nozzles.
We appreciate the input. Thank you! Feel free to send additional ideas to us at: corporate.hunt... If you have any questions, please contact us at: [e-mail]

Hunter Innovation Team"
There you have it, the new blue nozzle risers should fit fine in the older red nozzle body! For some reason I had difficulty getting the blue/red combo to work on the first time I tried mixing them and thought they were incompatible. Must have been operator error! :)

I've been using Hunter PGP sprinkler heads in my yard for over 10-years, I find that they are more durable and easier to install than other brands.
Now that the system is getting older more and more of the original PGP heads are beginning to fail. Thankfully new PGP heads are in stock at my local big-box home improvement store at a great price. I've gotten pretty good at replacing the old PGP heads with new ones.
PGP heads come with a set of instructions, alternative nozzles and a great multi-tool. But there is one tool I've bought and two tools that I've made that make swapping heads much easier, often with no digging needed.

[@Koolbob2]

PLEASE READ THE VIDEO DESCRIPTION - I was mistaken when I stated that the Red and Blue nozzle PGP sprinkler housings were different. Hunter Industries has confirmed that Red and Blue nozzle PGP housings and rotors are interchangeable. Thanks!

Outstanding video!!! SIR, you have simplified my life, first thing I did was make a "removal tool", and YES, you should have patented it. Life is so much easier now with much less digging😍

[@Koolbob2]

Our irrigation system is about 20-years old now and I just replaced another PGP head using my tools a couple of days ago. I usually end up replacing a few each season and I've pretty much perfected my technique and can replace and raise a sprinkler head using only my two tools, the adjusting tool that comes with the head and a small hand spade in only a few minutes. I still can't believe Hunter Industries wasn't interested in my tools, but I'm always happy to hear they have helped a fellow home owner.

Great video and helpful tools. When you removed the blue nozzle with the needle nose pliers you said to turn 90 degrees. You actually turned it 180 degrees. That was a great tip!

[@marcrocha3433]

if you look on the white Hunter tool there is a half round cutout on one of the finger holes with two tips that fit the slot of the Blue Nozzles you can use this to rotate the nozzle out of the body :)

I’m an irrigation tech. You’ve got some great ideas. I like the tools u made. There are bent locking pliers that help remove and install the head.

I inherited my sprinkler maintenance responsibility when my landscaper told me last year that he did not want anything more to do with my 13 year old system. So I went through multiple you tube videos, purchased some tools, spare parts and even made a very similar PVC wrench that I notched with a Dremel tool. This video was one of the best I found. The only problem I have is the comment that just replacing the guts while leaving the housing in place will not work. I’ve replaced five heads that way and they all seem to be working fine? What part of it doesn’t work when you reuse the housing?

[@Koolbob2]

My situation is similar, the one affordable sprinkler installer in town retired and that is how I got started repairing my own system. I couldn't get the splines to engage properly the first time I installed a new Hunter PGP core in one of the existing bodies, so I assumed there was a design change between the old and new PGP heads. My assumption has been proven wrong and I've mentioned this several times in the comments and in the information below the video, sorry for any confusion that may have caused. I'm still relatively new to KZbin and haven't yet found a way to edit a video once it's posted. I'm glad to hear the video was helpful and that the PVC tool is working to make your maintenance easier!

[@ed2699]

@@Koolbob2 thank you Koolbob! I looked further and found the post from Bryce and your summation so now I’m not sitting and waiting for them to fail. I designed my tool while l shopping in Loews and decided on a T connector with a kind of Y shape off to the side for leverage. So now your video is perfect!

[@ed2699]

I saw a video tip where the guy added water around the hole before removing the body to keep the dirt in place after cutting the donut. Pour in some water and wiggle the body a little to press the dirt in place. Love these tips! Thank you

[@Koolbob2]

@@angelae6064Thanks for watching and taking the time to leave a comment! I've set my system to run at 3am, 4am and 5am for a few minutes at a time. I run it very early when the water pressure is strong, there is less evaporation and only 15-minutes as a time so the water can soak into my hilly yard, rather than running off. Every month or so I like to run each zone for a few minutes during the day and check that all the heads are working properly. I usually discover I need to replace a head during a test, so the soil is already damp. Sometimes the ground is too wet from a malfunctioning head or the head is at a low point in the system and if I remove the head the hole will fill with water so I wait for a day or so before working on the head. If I ever find myself attempting to replace a head when the soil is dry I'll definitely try your tip!

[@lathamarea1437]

I love Hunter heads, they're very easy to adjust the spray pattern and rotation with a small flat screwdriver..When removing the sprinkler from ground i removed the inner body and simply used two pairs of pliers, egging the hole before taking out completely ..That packs any loose dirt from falling into water line..

I have the adjustment tool but on some of my sprinkler heads I can't seem to get a bite on the screw head. Is it possible some of the adjustment screws use a slotted screw head rather than an alan head? Great video and kudos on your creativity with the tools you created.

[@Koolbob2]

Thanks for watching! Often the hexagonal hole in the Allen head adjustment screw gets filled up with dirt, making it impossible to get a grip on the screw with the Allen key. You need to clean the gunk out of the hole so the Allen key can get a grip. I have an awl with a sharp tip that I use to loosen up the debris and then I loop a short bit of tubing to direct the water stream from the nozzle onto the Allen screw to flush out the debris while the head is spraying water. You can also try using your garden hose, pump up sprayer or a spray bottle with water to flush out the debris. I'll make a video on this this weekend and upload it!

[@JohnTubeOwens]

Hi Robert - this is fantastic and very inventive on your part. I attempted to take apart one of my older PGP rotors and need help. What is the best way to take it apart. Thanks.

[@Koolbob2]

Hey John, It should be pretty simple, unscrew the collar at the top of the sprinkler head and pull the collar, head and rotor assembly out of the hollow body. Sometimes it takes a pretty firm pull, especially if there is any sand or debris that worked it's way into the innards of the sprinkler.

[@JohnTubeOwens]

@@Koolbob2 That was no problem. I took the inner rotor assembly out of the hollow body and am attempting to remove the top section - head, that rotates. I picked up a 4" rainbird sprinkler as you showed and will glue to the empty inner housing once I have the innards removed. What am I missing to remove the head and get the innards out? Thanks.

[@Koolbob2]

@@JohnTubeOwens Ah, now I understand your question. It's been a couple of years since I made that tool, so my memory on how I disassembled the guts is a bit fuzzy and I don't have any broken PGP heads at the moment that I can mess with. I do remember removing the rubber cap and then getting the guts out but I don't remember if there was a screw under the rubber cap or if I just ripped the guts out. If all else fails, you could just cut the top off with a hacksaw.

Bob, great video. I need to cap off one of my heads (this exact kind PGP-ADJ) and I can't find what I need. Recommendation?

[@Koolbob2]

I am not aware of any way to cap off a Hunter rotor. I had a 4" RainBird head I wanted to cap off and purchased a cap that replaced the guts of the sprinkler head so you would leave the empty sprinkler body in place. So much water gushed out around the cap that capping the head actually put more water on the lawn than leaving the head in operation. I ended up completely removing the RainBird head and capping off the riser with a short section of 3/4" PVC pipe and cap. I tossed a handful of misc nuts and bolts in the hole, just below the surface so I could locate the capped off PVC pipe with a metal detector if desired. I hope this helps you with your situation. Please subscribe and like if any of this is helpful!

[@BRISTOLFORCE2009]

All types of pgp rotors fit into the same canister, it is the same rotor just with different nozzles

[@ck-4203]

Teflon tape on riser threads might help seal.

[@Koolbob2]

I suppose there's no harm in adding teflon tape, but it isn't necessary because the threads on both ends of the riser are tapered so they get pretty snug before the threads bottom out.

Thank you for the great info. So to be clear the Orbit riser works with the Hunter heads...without issue? Many of mine are very Low. I would love a way to raise them without digging them all up.

[@Koolbob2]

Yes, the Orbit risers come in 1/2" and 3/4" diameters. My local HomeDepot keeps the Orbit 1/2" diameter risers in stock, but I had to get the Orbit 3/4" risers from Amazon. The Orbit risers are made from a very soft plastic, it seals very well, but be careful not to cross thread them or you'll mess up the riser. Get more than you need just to be safe. I ordered a 20-pack so I'd have enough for every head in the yard, plus a few spares. www.amazon.com/gp/product/B07MCYX3VK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

what is different between red nozzle and blue nozzle bases? I just installed a new blue nozzle head into my old red nozzle head yesterday and seems to be working fine, so what trouble did you experience in doing that? thanks for tips on tools ,looks like a great Idea.

[@Koolbob2]

Mike, thanks for watching the video and taking the time to comment. You are correct that the actual red or blue spray nozzles are interchangeable. the point I'm making is that inserting the entire internal rotor assembly (guts) from the newer 'blue' nozzle heads into the older 'red' nozzle housing (shell) that is threaded onto the irrigation pipe won't work properly.

[@PTAC2023]

@@Koolbob2 I installed a new Hunter PGP rotor (w/ blue nozzle) inside an old PGP (w/ red nozzle) housing and it seems to work fine. (To be clear, I replaced the entire insides by unscrewing the cap at the top and left the housing screwed into the riser.) Can you tell me what issues to look for, I may not have noticed it, yet. Thanks and thank you for a great video.

[@Koolbob2]

@@PTAC2023 It's been a few years, so my memory may be fuzzy on this, but when I tried just inserting the blue 'guts' into one of my 10-year old existing red housings the splines on the inside of the red housing didn't engage properly with the groves on the bottom of the blue guts. I struggled to get that red/blue combo to work, so I replaced the entire red sprinkler with the newer blue sprinkler and everything was fine. I've stuck to the notion that red and blue housings are not interchangeable ever since. I think there's one red sprinkler left in my yard, not sure if it was an original 10-year old version, or one of the replacement red sprinklers I've installed over the years, but when it dies I'll try to use blue guts in it and see how it goes.

What tool did you use to make the notches in the top of your 2" pvc. And Ajso what did you use to space the notches so exactly?

[@Koolbob2]

I held the PVC pipe up to the top of the PGP sprinkler and made marks on the pipe where the notches needed to be with a sharpie. I then put the pipe in a vice and cut notches with a hacksaw, but now that I have an angle grinder I would use that with a cut-off wheel.

[@federicosole1751]

Excelent video!!!!!!

[@mikeallumi6507]

I thank you for all the info, and tool selection. I have been changing some of my older sprinkler (Hunter) heads as they age. I have just tried, and still trying to replace to heads that were bad. Basically no problem, but trying to set up these new heads has its challenges, at least for me. I am left-handed which usually doesn't cause much concern, but when setting up the new heads. I put the new body on the existed male connection, then I put the rotor in, so I can get the right amount coverage, but when I go to tighten the rotor cap, it is very hard to turn, and both of these new ones have leaked, or I have turned the rotor cap so that it turns the body, and I have lost my right side stop position. So is there something I can put on the threads of the cap to make this tighten up so it doesn't lead and I don't mess up my right side stop.

[@Koolbob2]

Hey Mike! I think I understand the issue you are having, here's how I install an entirely new head, maybe this will help. PGP heads come adjusted to cover about 180-degree rotation, the right stop is fixed and the left stop is adjustable. Unless the old sprinkler body is stuck in place, I install the entire head (rotor body and rotor guts) just as it comes new. I push down on the rubber rotor head with the palm of my hand and turn it all the way to the left stop and then all the way to the right stop. Now I know where the right stop is on the sprinkler head and I begin threading it onto the existing sprinkler head riser buried in the ground. As I tighten the head I keep an eye on where the right hand stop is so I can stop tightening the head in place when the right hand stop is pointing where I want it to. If I miss the mark and the right hand stop close to where I want it I can just tighten or loosen the head on the riser threads to get it in place. If the head is nice and snug and the right hand stop point is way off I hold the body of the sprinkler in place (a big set of channel lock pliers comes in handy to gently hold the body in place), unthread the cap, pull out the guts out, rotate them as needed and reinsert the guts so the right hand stop is where I want it to be. I was already thinking about making a Hunter PGP install video when I get a chance and your question has encouraged me to go ahead and make a video, so subscribe to my channel to receive a notification when new videos are posted.

[@mikeallumi6507]

@@Koolbob2 I agree with what you say, but I can not tighten up the cap sufficiently after I make my adjustment. The sprinkler head continues to leak, from under the cap. I am an old guy who has lots of arthritis, so while I had the body help with a pair of channel locks, I had a second pair of channel locks, trying to tighten up the cap, but the cap didn't seem to move. I started the cap by hand, so I don't think the cap was cross threaded, but for some reason, (probably me) I could not tighten up the cap to stop the leaking from under the cap.

[@Koolbob2]

@@mikeallumi6507 If you are using on old sprinkler body with new internals, then the first thing I would try is using the both new body and internals together. I can only think of two things that might make an all new sprinkler body and internals leak and that is cross-threading them or foreign material getting in the way. Be sure everything is clean and dirt/mug free and there's no grass or roots coming in-between the body and top. As a last resort, replace the problem head with a new PGP that you have not disassembled and I'm sure the leak will be fixed. One last thought, could the leak be coming from under the sprinkler head and rising up around the sprinkler head and looks as if it's coming from the top?

Good suggestion, I'll have to figure out how to do that.

[@sarahmooradian4775]

Great video. What did you use to cut the PVC?

[@Koolbob2]

Thanks for watching! I cut the PVC 'tool' off a longer section of PVC pipe with a reciprocating saw with a fine-tooth blade. I then put the 'tool' in a vice and cut the notches with a hacksaw and refined the notches with a Dremel tool until O got all of them to fit the PGP cap properly.

You might think of a patent. Someone will steal your idea for this handy tool.

I've submitted my video to Hunter Industries R&D, but have not heard back from them.

@koolbob2 Can you fix a non-rotating rotary so that it rotates again or is that not an option?

[@Koolbob2]

I keep a few spare PGPs for when an old one quits rotating or the seals begin to leak (creating a large puddle around the sprinkler). Hunter sells a seal kit, but it's so much easier to remove and replace the head as opposed to order the seal kit, remove, disassemble, replace the seals, reassemble and replace. I've always assumed that heads quit rotating because the gears are worn out and the head has reached the end of it's life. I suppose you attempt to repair the gears if you could get to them, but it would be time consuming and probably a short lived repair.

[@kencarlsen2212]

When the nozzle is unrestricted it seems more water goes to the far end than between the head and that point. When the nozzle is restricted, to shorten the distance, it seems the water is more evenly distributed across the distance. Any comment?

[@Koolbob2]

I agree that the water distribution looks better when the adjustment screw makes at least a minute amount of contact with the water stream. Keep in mind that there is a LOT more square footage of lawn at the outside of the sprinkler's arc than near the inside, so no need to try to make the distribution even from the head to the end of the sprinkler's throw.

I have these sprinkler heads and the water is not as “full” as I’d like. I’m wondering if you know how to clean the filter?

[@Koolbob2]

Hey Jennifer, I've never cleaned the screen on a Hunter head, but here's a video on how it's done. www.hunterindustries.com/videos/cleaning-filter-hunter-rotor

[@jennifernorton8975]

Do you think it could be the problem? ( dirty filter)...I have spent so much $ on this system, as I’m not as savvy as you. I have water, though every year I need to put pellets down my well, to clean the well tip. Now I’m wondering if the rust has yucked up the sprinkler filter? I’ll watch the video, thanks!

[@Koolbob2]

@@jennifernorton8975 I wish I could be more helpful, but I don't have any experience with wells or pumps. My first question would be what is the pressure and flow of your pump? To find out, buy or borrow an inexpensive ($10) water pressure gauge and a 5-gallon bucket. Screw the gauge onto an outside faucet to measure the static water pressure of your system. Then time how long it takes to fill the bucket with the faucet all the way open. There are resources on the internet to help you calculate how many sprinkler heads can operate at the same time with your pressure and flow. If you have too many heads on a single circuit, you can switch to lower flow nozzles on each of the heads to improve the spray pattern (then you simply water for a longer cycle to compensate for the lower flow rate). Our neighborhood has a well system and our pressure was only about 35PSI when our system was installed many years ago. Since then the city has taken over management of our well and the improvements they have made increased he pressure to 45PSI so now I can run higher flow nozzles on the areas of the yard that need a little extra water. I hope this helps.

I suppose you could put something like a toothpick along the side to hold it from going down...and just taping the stick or whatever you use to the body while working on the nozzle area.

Great work arounds...did you ever patent these?

[@Koolbob2]

Thanks! I've shared my tool video with Hunter and while I'm waiting to hear back from them, I've begun the patent process.

[@mtnewton5219]

How do you shut off/ terminate water going thru the nozzles. Some of my heads I no longer need .

[@Koolbob2]

I needed to cap off a 4” RainBird pop up head last year. I bought a cap that is supposed to replace the sprinkler ‘guts’, but it leaked terribly. I ended up digging up the head and capping off the elbow fitting that the sprinkler head attached to. I also threw a big bolt the hole the head came out of before filling it, that way I could find the sprinkler connector with a metal detector if I ever wanted to put the head back.

[@mtnewton5219]

Thanks, I really need a way to cut off a Hunter PGP head. I'm looking for a nozzle W/O a hole.

[@Koolbob2]

m t newton - I guess you could plug the hole with a sheet metal screw and some epoxy, but the head will still rise and rotate when the water comes on until it wears out. IMHO you will be better served if you remove the sprinkler head entirely.

[@kozak65]

Capped PVC so it sits 2 inches above the soil.

[@ofcbob6391]

@@mtnewton5219 Did you ever find a proper fitting "cap" for your PGP? I have the pretty much standard PGP-ADJ sprinkler heads. I see below KoolBob2 suggests plugging the spray hole with a sheet metal screw. That sounds logical to work. I don't care if the head still pops up and rotates.

How can you remove the top without the can turning and coming loose from the bottom

[@Koolbob2]

I use my homemade removal tool on the top of the sprinkler, sometimes the entire sprinkler head turns and can be removed, sometimes only the top portion turns and I am able to remove the 'guts', leaving the housing in the ground. That's why I made a second tool to remove the housing should the guts come out on the first try. The only way I know to remove the entire sprinkler head on the first try, guaranteed, is to dig out around the head and rotate the housing with your hands.
