One of my Hunter PGP Rotor Sprinkler heads developed a common problem with its seal, which caused a considerable amount of water to leak out.
Now these heads can be simply replaced, The Home Depot carries them and I could have easily replaced the entire unit. However, I was able to find a replacement seal online for under a dollar. By replacing the seal, you are not only saving money, but avoiding the hassle of adjusting the new sprinkler. So it saves you time and money.
Video explains the process, which is very straightforward and no tools are required!
Extremely helpful video! This certainly helped to save me a lot of money by changing the seal rather than having to replace the entire head. You made it look so easy. Thank you!
Thanks for your great video! To make sure that the dirty water which you flushed out does NOT go back into the pipe in the ground, I would suggest getting a 3/4 inch PVC pipe with a threaded adapter and temporarily screw it in maybe a turn or two. The temporary flush pipe should be long enough to extend above the ground and the grass. Then flush the system and the dirty ground water won't run back into the pipe. For most other smaller sprinkler heads, you would need the appropriately sized half inch flush pipe and adapter. Update: I just saw another great tip thanks to one of your commenters, add a 90° elbow at the top of this flush pipe to direct the water away from the hole.
This was precisely what I was looking for. I had no idea how the caps on the Hunter PGP head pop-up sprinklers were kept on, or how they were supposed to be removed. A lawn mower ate the screw-on cap on one of my heads, and it is of a type that is so long(or tall), that it is no longer advertised for sale at any of the local big box stores. And a replacement cap and seals were all I needed. I keep a big box of old and/or spare Toro, Rain Bird, Hunter and no-name sprinkler parts around for repair purposes, so this fix should only cost me my time, which, as a retired person, is not worth much. Thanks for making this video, and please keep making them. You have a great way of explaining things on camera.
I've had 8 Hunter PGP rotors in use for about 27 years in my garden in NY City. They haven't been touched in all that time but three need minor servicing now, for small leaks. Excellent product.
Great video on rotor replacement right up until the part where you put ANOTHER PGP in the ground. If your PGP has failed--like many others, replace it with a better-performing product, such as the T5 Rapid Set Rotor from TORO. My contracting company switched from PGP's to Toro a few years ago because we were tired of customer complaints on seals leaking. We were changing over 2,000 rotors a year due to seal leaks. With Toro? NONE! Great product, higher pop-up, better seal, better nozzle, check value included no additional cost AND a 5-year warranty! I am making a great living replacing PGP's with Toro's T5 all day long. Thanks for the video, Jay!
Great video. I just replaced 3 of my Hunter PGP sprinklers because I saw water leaking around them. I wished I'd watched your video first. Since I didn't throw them away, I'll take a deeper look at them and if there is no damage to the bodies, I''ll replace the respective combo seal and retainer rings as you did in this video. That way if I have any additional ones experiencing issues, I'll replace as them as needed with my rebuilt one(s). Thanks for the excellent video!
Appreciate the time and information provided to maintain this type sprinkler head. Will be tackling mine tomorrow. 👍
I was getting ready to fix my sprinkler head and this video helped me get prepared. Thanks.
Great video, very helpful. Just fixed my sprinkler today. Thx a lot. Greetings from Germany.
Just noticed this problem on one of my sprinkler heads. Was going to buy the entire head, now I know how to replace the seal.
This was very interesting and useful to me when I go to make repairs to my sprinklers thank you .
I just got ordered me some of those seals, I hope that fixes the issue. Thanks for the video!!!
When I first bought my house, my sprinkler sytem was mainly made up of Hunter PGPs and these Toro heads from the 90s. A few of the Toro and Hunter heads still remain but most of the sytem is a mixed bag of different brands as an experiment of mine. As of now, I think most of the brands perform pretty much the same.
For all the haters out there, the PGP rotors are what the irrigation company I worked for back in the early 90s used and we never had maintenance calls for those. Rainbird & Toro on the other hand, numerous calls! Fast forward to 2018, my house that i bought new in 2009 had hunter pgp rotors and they just started leaking at the start if this season. So, I ordered 25 new seals and have a weekend project. I bought new seals for a total of 0.46 per seal. Way better than paying $7-9 per head. Given these are Hunter replacement seals, I dont expect any issues with them and will get another 9 years out of them.
There is another cause for a leak that wasn’t mentioned. In my case the screw on cap had a hairline crack. One could think the riser seal needs replaced but really it was the cap.
very helpful and easy enough rather than having to replace the entire head. thank you!
Thanks for sharing your knowledge .
Perfectly explained! Thank you
Jay, I think you might have haters who are disliking your videos. Great video!
Line Hunter heads to the right side,not left in case you need to adjust the variable side(left) with the key. Good vid
