Dripper System and constant valve flow

Posted by GardenViewer none (My Page) on

I have a 5 valve dripper system system connected to a Raindial rd600 timer.

In one box is 2 valves and in the other box 3 valves. They are connected to the same water line but it looks as though the 3 valve box is newer. I'm not the original owner of the property so I'm not sure about the setup although I can take pictures, describe, etc.

Anyway, I have the water turned off from the side of the house to the irrigation system. When I turn the water on valve 1 is open and i pushing water through. In other words, all of the drippers that are connected to valve 1 will start dripping water.

On the 2 through 5 I have to press a little lever near the solenoid to turn them on. Once I turn them on if I flip the lever again it doesn't turn them off, I have to go to the side of the house and turn the water off to the irrigation system.

Further, when I use the Raindial to manually turn on, for example, valve 5 for 2 minutes it doesn't turn it on and the timer on the dial for valve 5 goes back to off. In other words, it doesn't seem as though the solenoid is doing its job even though I have manually taken valve 2 solenoid off, hooked up dirrectly to common and valve 2 in the Raindial station and I can hear the solenoid and see the end flick. I've also replaced one of the valve solenoids with a brand new one to see if that was the issue and still the issue continues.

So bottom line I have a few issues here and my knowledge of this isn't at the level to know what is normal, what is wrong and what to do to diagnose. I am posting this rather than paying someone to come out because I like to learn and want to be able to handle this and future projects myself.

Here are the ultimate run down issues:

1) When I turn the water on from the side of the house to the irrigation system that feeds to valve 1 through 5 the water goes through valve 1 into its' attached drippers to start dripping water. I have replaced the solenoid and taken apart the valve to see if there were any rocks but no debris. I thought that all valves are "off" by default and so it shouldn't automatically start dripping from valve 1 when water is turned on.

2) When I use the Raindial timer and pick a valve, say for example, 5 (or 2, or 3, doesn't matter) and manually set it for a few minutes and press start sometimes I hear a flick but ultimately the Raindial then shows OFF for that valve and the water is not flowing through that appropriate valve drippers. I know this is not normal because years ago I would do this when I was locating all of the drippers per valve and the timer would count down for that valve to when it will close it. I have replaced the Raindial fuse.

Any help, suggestions, links, etc would be greatly appreciated. Thank you so much!

Have you tried to start the zones by rotating the solenoid itself. Counterclockwise starts the zone (move it only until the zone starts, do not unscrew all the way). Shut the zone off by turning the solenoid clockwise until the zone goes off, do not over-tighten the solenoid. Let us know if this fixes zone one and the others. I would also redo all the wiring connections at the twist connectors as well as at the controller. Use new water-resistant screw twist caps (gel filled). If you want replace all the solenoids while you are at it. It is not very expensive to do. Let us know what transpires. Aloha

Thanks for the quick reply. I came down with a cold and haven't spent any time out working on items such as this. I just got out there today and a neighbor must have locked my dripper system timer because it is locked and I didn't do it. haha, so i'll track down a key since I believe they are all generic and all of our neighborhood has the same dripper system timer.

Onto your suggestion: I haven't found that turning the solenoid does anything.

GardenViewer, "...I haven't found that turning the solenoid does anything."
If you mean that the zone is turned on and off, like lehua13 said, then the water supply and the valves are functioning.
That leads to the conclusion that there is something amiss with the timer.
