How to Repair or rebuild a hunter sprinkler control valve 

My question was answered within the first minute of the video. "Are they interchangeable"...............you are "The Dude"!!!!! Thank You

Thanks. This is the kind of instructional video I like to see. Would be good to see you do this in the real world with an existing system!

Thank you so much for this. This is a repair I'm about to take on this afternoon and your video gave me confidence that I'm not about to do something stupid :)

Hi Justin. I have a hunter hgv valve that am rebuilding for my residence. your video is spot on.....however, it is vital to order the right parts for your model.

Excellent video. Just what I needed to rebuild a Hunter PGV.

I know this video was 5yrs ago but GREAT info. Very well done. Helped me out alot. THANK YOU.

also, a great point to make here, is that a faulty solenoid will always be in the "CLOSED" position. at no point will a solenoid fail and remain OPEN. therefore, if your zone is not shutting off completely, most, if not all signs point to a faulty diaphragm. although you may as well replace them both while you have the valve apart. great video, BTW

Thank you so much, after watching this video it was a piece of cake to fix my system who was leaking.

Great video. Thanks for sharing your expertise with those of us who are Do-It-Yourself homeowners. Next time, please shoot with the sun at your back. Much of the black parts are in the shadows.

Very good advise about opening a control valve in the field to go ahead and replace internal parts.Thanks. I should have done that The first time.

I have found that when you are replacing a screw in plastic you can turn the screw in reverse very slowly and you can feel when the screw drops into the original threads rater than starting off tightening it and cutting new threads.

Very informative and easy to repair thank you

Great! Didn't think I could just change out the parts! Harris County ,TX

Good instructions. Very informative

THANK YOU JUSTIN - EXACTLY WHAT I NEEDED. THANKS FOR BEING THOROUGH.

Thanks it was helpful even though I have older series valve assembly.

Have a much older system with screw on top but video was still helpful

Good Job Clear instructions

Nowhere did i hear the advise to the homeowner about shutting off the irrigation main prior to opening valve. If you dont, you will be surprised!

It would be nice if the camera was positioned so that we could see what he was referring to. At least he refers to the spring and it's function. This component weakens with time and is frequently the real cause of valves continuing to pass water when they are supposed to be closed. He is right to say replace the essential components if you can get them - the diaphragm and white ring, however, can be cleaned, as long as they show no signs of damage. Always replace the springs if you can get them!

Great instructional video thanks for the help.

Ehhhh from Georgie !!!!!!, I’m from pflugie!!! Hi neighbor!!!!!! Nice troubleshooting Thanks

This helped greatly.

Good video! Helped a lot.

Great advice. I’m sure it’ll save me a few hours You

Great video

Justin, I replaced the valve inserts and the solenoid on a Hunter valve. It solved the problem for that zone, but now the other 3 zones don't come on (they worked before). What did I do wrong?

i would like to kow how to drain the air and what is the open and close position meaning on the selenoid

Thanks for the great video!!

When you say it'll even dentation on the seat can you actually show it in the video? Since this is a video format. that would be really helpful to actually see what you're talking about especially where you have the valve out and it's not in a sprinkler box and you should be able to easily show it in a video format.

I hope the diaphragm tip is helpful. I'm going to Home depot later to get a replacement

Thank you very helpful

The old valve doesn't have flow control right? I don't like my pressure, and I found older version installed which doesn't have flow control knob. Does it mean old valve just runs at maximum flow all the time?

I rebuilt my valve, replaced the selenoid and it still won't open. It's getting power. Makes a buzzing sound and it can be opened manually.

TY yes it helped a lot

Hi Justin! Thank You for your video! I have a Hunter PGV! I cleaned the exhaust port and that worked. For one cycle, the next day I go out and the valve box is full of water. I drain it and clear the port again. Same as before, it worked once and the box has water in it again! The water fills the box only when the valve is activated! HELP

Justin, when I turn a solenoid total clockwise off I don't get any flow I have to turn the solenoid 1/4 back from off

Hi Justin, I am European but my thoughts are with the people in Texas that currently have more water in their garden and city as they like. I have problem with my system. One of the valves opens every 3-6 minutes for a few seconds. My gardener replaced valves but the problem is not resolved. He is frustrated because of beiing over the edge of his knowhow. I am an engineer with some but not enough knowhow on hydraulics. Do you have any clue where the problem could be?

Mine squeals when I run the sprinkler, what would be causing this? Hope to hear back! Thanks

Hi Justin - Thanks for posting, great video. One question - when repairing a valve, what position should the solenoid and the other top screw (I think you called it a bleed port) be in? I have a sprinkler system that continuously runs even when the controller box is off, and I noticed both the solenoid and bleed port can be turned tight or opened. Thanks!

how would you change a diaphragm in a valve box that has debris in the valve body? I want to be able to properly flush a valve without filling the valve box full of water - valve boxes for the most part are not clean and things float around and get sucked back in. How would you properly flush a valve without filling it with water?

HI Justin. I took my 3/4 above ground Hunter anti siphon valve apart to clean it and to make sure that there wasn't any debris causing issues. My valve would NOT close and the second valve opened when the second one was supposed to start. I noticed that both valves were trying to spray water at the same time. While I had the valve open I took my compressor to clean out any debris that might be clogging the ports. I noticed that 2 very small screen fell out of the valve! I do not know where those tiny screen are supposed to be placed back into the valve! They're about the size of my nail on my pinky finger! I checked out the solenoid with a small battery and it operates correctly. Any ideas on why that valve would not close when it was programmed to close?

Hi Justin, Thanks or the comments and tips on the video. I just rebuilt valves and am having issues again. I didn't replace everything and so maybe I missed something. You said you work in Phoenix? What part? Do you have a link to your business site?

I have 1 sprinkler that has been running for two days. How do I know which valve it is connected to. I tried running the zones but I think it is in a zone I don’t use anymore since we installed a pool. Can I just cap off the sprinkler and not use it?

Zone 1 seeps water through the heads for few seconds each time start/run a diff zone. Does that mean zone 1 diaphragm needs replacing? Or something else needs replacing? Help

thanks it helped

thanks

Justin what is that white ring called where the diaphragm sits? I replaced the solenoid and the diaphragm and I just noticed that some videos showed the ring and my SRV valve did not have that when I removed it? I’m wondering if that is what’s causing that particular zone to continue to run🤔

I replaced a diaphragm on my Hunter SRV 1" Valve due to the fact it was leaking. I installed a new solenoid as well. I removed the old diaphragm which was distorted with a new one and all was fine until the next morning when I woke up and the zone where I replaced the diaphragm was running wide open (all heads) with the sprinkler system shut off (unplugged). Any ideas?

Hey justin, thanks for the video. I have one question. I'm replacing the o ring I have the right size and everything. But the plastic screw on doesn't tight up at all. Am I missing something???. It still leaks. But I know it's not screwed on properly. Need help. Thanks.

I did this and my hunter pgp head still leaks while system is off. I replaced the diaphragm twice, then replaced the top half and still leaks. Any suggestions? Oh yeah I took the sprinkler head off and water is still flowing through line.

Will Lowe's or home depot have these on shelf??

REPLACED ALL PARTS ON VAVULE AND VAVULE STILL WONT SHUT. STILL RUNS WHEN OTHER ZONES ARE ON. HELP

Good now knowledgeable video?

Bad lighting, had no idea what you did

Too much shadow to clearly see what is going on

Video is out of focus. :( Sun needs to be behind you.

You explained nothing.
