Well done Mike, Maybe one of the best tutorials I've ever seen. I now understand exactly how my anti-siphon/in-line valve works. Thanks! PS This video is an example in professionalism and efficiency, as well as a reflection on what kind of company Hunter is? TOP NOTCH! .
Hello..I have Hunter Node 100 where water is not stopping ...guess need to change diaphragm but I can find diaphragm for Hunter PGV. Can one for PGV fit into Node 100?
The Hunter Node is battery operated controller and does not have a diaphragm. The PGV valve *does* have a diaphragm which can be purchased from your local Hunter distributor. Here are the details on servicing a valve but make sure there's no debris left inside. ua-cam.com/video/72Y3mmZLNyo/v-deo.html
lets say the irrigation system pressure is not properly regulated, should the valve stem(flow control) be turned all the way to the right (clockwise), the left, or middle? Same question for the bleeder (small relief screw). Trying not to put too much strain on the valve.
Thank you for contacting Hunter Technical Support. The bleeder screw can relieve a little or some air trapped in and around the pipes going into the valve. There is a better product application to install to help relieve any air trapped in the system. It is called an air relief valve. The AVR offers a commercial non-corrosive solution for releasing adequate airflow at the high points of a micro-irrigation system during start-up and shutdown. This helps stop water hammer and resulting system damage. The AVR will also prevent system collapse through vacuum relief. www.hunterindustries.com/irrigation-product/micro-irrigation/airvacuum-relief-valve
Thank you for contacting Hunter Technical Support. When an irrigation zone is flowing enough water through the piping that the velocity is greater than 5 feet per second, the system will start to water hammer. You may hear pipes shaking or squealing noise coming from valves. Not all water hammer is noticeable because the piping is buried or irrigation is scheduled when no one is around. Water hammer puts a tremendous amount of strain on irrigation components, even if you are using a pressure regulator. Water has a specific weight that when traveling at fast speeds can act as a battering ram inside the pipe and beat up pipes, heads, fittings, and valves. The best way to reduce the water hammer is to design your system with an appropriately sized pipe for the zoning requirement. If your pipe is already in the ground, there isn't much we can do about the sizing. You can tune your valves by using the valve flow control feature. Here are the steps: · Start with your valve flow control wide open. Turn the valve on from the controller. · Start to turn the flow control knob clockwise until you start to see the spray from the sprinklers drop. · Stop and open the flow control half of a turn. · The flow of that valve is now tuned to the zoning requirement. If that does not solve the problem, water hammer arresters can be purchased and installed to try and fix the problem. Please contact a local irrigation distributor for assistance.

The reason for each adjustment capability is different, although their effects are the same. The bleed screw is designed to release unwanted air from the body of the valve. Using it also causes the diaphragm to open, and the valve to turn on. Turning the solenoid manually causes the water to be displaced and the pressure on the bottom of the diaphragm to be greater than the pressure on the top, causing the valve to turn on. This is the method designed specifically to turn the valve on "manually"
No water coming out from quarter turn. Shut off water, removed the solenoid and the o-ring was broken as well as the diaphragm was separated from the solenoid. I pushed a new o-ring all the was from the metal part close to the diaphragm, pushed the metal piece back into the solenoid and then screwed the valve back in. Turned on the water and did a quarter turn test. Still no water coming out of the sprinker heads. This is the only one that I have an issue with. All other zones working fine.
Thank you for contacting Hunter Technical Support. If the solenoid is good, there is also a chance that the exhaust ports within the irrigation valve are clogged. This would require you to clean the ports in the valve. Learn More For additional support for Hunter valves please visit the support page. Thank you again for contacting Hunter Technical Support.

Nice video! I have the same valve as in your picture. I can’t get the valve to shut down that last 20%. I put your rebuild kit in and the same. Unfortunately, someone decided that a rebuild kit should not contain a new solenoid. Do you think that might be the problem?.

Have to say - all HUNTER videos on UA-cam are top notch quality! Very professional, simple, quality information, easy to follow and understand.
Wow, thanks!
Mr. Mike thank you very much for that excellent tutorial 👍
You're welcome

Thank you for the vid! Made it much easier to understand how to use it with an XC-H
Glad it helped!
Great video. I understood what you were talking about immediately, and I just started learning about irrigation systems today!
This was awesome and fixed my problem. Thank you!
You're welcome
Good explanation, video professionally recorded (not jerking around like hand-held video). Thanks.
Thank you for a Great video! I understand my Hunter system better now.
Glad it helped!
wow . . . great explanation . . . presentation and detail are outstanding. . . thank u
Glad you liked it!
Very easy to follow. Great job. Thank you
Very good tutorial. Thank you!
You are welcome!

What should the impedance be in Ohms across the solenoid? I have a hunter number 1412. Thanks a lot Mike.

Does the bleeder screw remove air trapped in the pipes?

@@Hunter_Landscape_Irrigation Thank you for the information. I appreciate it
Is there a difference between opening the valve on the solenoid or the bleeder. I personally use either way.
The reason for each adjustment capability is different, although their effects are the same.
The bleed screw is designed to release unwanted air from the body of the valve. Using it also causes the diaphragm to open, and the valve to turn on.
Turning the solenoid manually causes the water to be displaced and the pressure on the bottom of the diaphragm to be greater than the pressure on the top, causing the valve to turn on. This is the method designed specifically to turn the valve on "manually"
What can I do, if the valve does not open manually. Meaning not with a control unit but from the solenoid like you did in this video. Pls Help!
Hi, Hunter PVG201 valve has flow direction indication?
No water coming out from quarter turn. Shut off water, removed the solenoid and the o-ring was broken as well as the diaphragm was separated from the solenoid. I pushed a new o-ring all the was from the metal part close to the diaphragm, pushed the metal piece back into the solenoid and then screwed the valve back in. Turned on the water and did a quarter turn test. Still no water coming out of the sprinker heads. This is the only one that I have an issue with. All other zones working fine.

If I use one of these type do I need a back flow preventer or is this type of valve an anti siphon?
What is manual bleed screw
