2 zones come on at same time
I'm using city water -- I have a intermatic timer, a rainbird antisiphon valve, and a 4 outlet index. I currently only have 2 zones hooked up to the index with the 2 zone cam. When I initially hooked the system up a week or two ago, both zones came on independently and worked fine. Now, when I manually turn on the system from the controller, both zones come on at the same time with low pressure. If i flip the switch dozens of times, eventually one zone will come on alone and will work fine. then when i shut it off and turn back on, it goes back to the same problem of both zones running at same time with low pressure.
What could be causing both zones to come on at once... is there something not triggering the index to shut one zone and move to the other? why is it trying to run both simultaneously?
I live in Central FL, no freezing or anything...
