This was all I needed to troubleshoot a leaky solenoid valve (not even a hunter brand), and it was a TINY piece of sediment that had lodged right along the edge of the diaphragm, where it seals agains the housing Thanks so much-just seeing how easy it was to take apart and but back together gave me the confidence I needed to jump in and try to fix it. Working great now!
I think he put that rock in their before the film. Because theirs no way a rock that big would fit in the entrance of that valve. Yet alone get in the pipe.
I have found that the spring is usually the cause of a steady flow of water when the valve is supposed to be off. I have replaced, cleaned and carried out the recommended actions without success. But if the spring is replaced, the problem disappears. I think the spring becomes weak and no longer strong enough to seal the diaphragm. This may be the case particularly with low pressure tank fed installations once the pump is off. If we are to believe Hunter, water pressure is instrumental in closing the valve. However, they do not say what purpose the spring has, and I think it to assist in pushing the diaphragm down against the lower surface so as to prevent water passing. A system with low unpumped background pressure may be prone to this problem. The valve can still work well with a fair amount of contamination, and you can make all the ports, diaphragm, surfaces etc very clean and still have a valve that will not close properly. I don't know where you can get a new spring from other than from within a new unit. Pretty crazy really.
what could cause debris to continually build up inside the valve? i have three valves in line and the last two have issues leaking because of the tiniest bit of sand/dirt inside every couple of months. i do this flushing procedure that you showed in the video and it fixes it, but it happens again a few months later.
Irrigation systems that regularly see sand and debris benefit from a system filter. Meet with your local irrigation professional or irrigation distributor for details.
i have replaced my diaphragm about 4 times in the last 2 months. that a bit excessive and unusual. I've clear the valve and made sure there were no rocks, sand, grass, what have you. the diaphragm seems to split in the same spot. not a big cut but big enough to turn my zone on and run constantly. i'm not sure what i need to do to resolve this. i'd love some ideas though
Thank you for contacting Hunter Technical Support. It sounds like the diaphragm support ring may be missing or damaged. Our support team can assist you if you need additional help. Please email support@hunterindustries.com
uh-huh... the underground repair performed between the valve box & the house which is literally about 1 ft from the valve box? no. it's coming naturally w/the water we drink... because the sprinklers r usually connected directly 2 the main water supply pipe.

You saved me $60. Thanks for the precise and easy instructions
Couldn't believe I'd have stuff under the diaphragm but sure did, 2 hard plastic pieces. Thanks for the video!
Easy and quick great video and really helped! Thanks
Thank you for the video!!

he is demonstrating wid his precious time and ur hopeless
Thanks, very helpful. Now I am going to Home Depot to get the replacement kit.
This helps and saved us money thanks!
Awesome! Thanks for watching!

Thanks for the vid, homie.
I once tried to pass a kidney stone that big. Needless to say the guy had to pop me open too.
Thanks
I'm curious about how they labeled that valve box cover. Looks good.
Thats an awfully large rock, I'm betting you stuck that in there. LOL For illustration purposes, of course.
how in the world the rock got in the pipe??????

@@Hunter_Industries A broken or degraded support ring can prevent my zone to coming On ??
oh look a toy car is stuck in there
SAVED ME A $200 SERVICE FEE!
From a possible underground repair performed upstream?
