Valve Questions

Hello,

I'm new to the whole sprinkler system deal and had a couple questions. I was hoping someone here could help me. I have a 13 zone system on my 1 acre lot. I have Rain Bird 100-DV valves. When I turned the water on this weekend I have mist spraying out of almost all of my valves at the spot where the arrow points. I replaced a diaphragm on two but they still do it. I called a sprinkler guy and he said the valve is most likely shot since thats where it was leaking. I'm pretty handy so I figured I could replace them myself, but looking at them more closely I had another question.

1) In the attached picture you can see the arrow with flow written in it. Water is shooting out right where it points. Is it a bad valve?
2) Notice how they have 2 valves tied together. The flow arrows seem to be contradicting. Should I install the same way as I take it out? The system has worked fine the last 3 years I've owned the house, so I would assume so. Logic just doesn't make sense though.

Thanks for the help!

If you are going to do this yourself, then you should map out all the pipes and plan for a complete rebuild with a different layout.

Did the backflow preventer (photo, please) survive the winter?

Backflow preventer is fine. I can get a picture later today.

I can try to completely remap it out, but could you explain how this has worked the way it is done? I can't wrap my head around how it has been working.

Cancel this thread lol. I'm an idiot. After further inspection there is an inlet water supply. There is a T in between each set of valves.

It was a given you were going to see that sooner or later, so I didn't bother pointing it out. The question becomes why, and how to deal with, the leak(s), since this would be uncommon if all the water had been removed from the plumbing before winter.

Wrong zone

When I set the control panel to manual, it shows zone 1 operating. In reality zone 4 turns on. When I set control panel to test cycle, zone 4 goes on. I tryed opening each zone at the valves themselves and each (including 4) turns on as it should. There are no crossed wires in the panel and each valve have 2 wires connected. Can anyone advise why this happening. I also disconnected the control box wire for zone 4, It still goes on as described.
