I just had the problem that zones 1 and 5 were going off together. I replaced the controller - same problem. Hunter suggested cleaning out valve / diaphragm - I did, but again same problem. Someone along the way described how a nicked wire made their system go berserk. I replaced the entire wire between the controller and valves. Voila and done !!!😀😀😀😀😀

But I have the same problem. If I turn on valve in the manifold box, #2 still comes on when #3 runs. So it's not the controller. DId this ever get solved?
