    Hey I need some input. I've got a 4 zone system that won't run. There is power at the box, 24-26 volts on every zone from the box to the selenoid, but it doesn't come on. One of the valves is brand new so I don't think that all 4 selenoids went bad at one time. HELP!

    Thanks in advance.

    Master valve?

    Do any of the zones work manually?

    Master valve or isolation valve not on? Like Jon says, try and manually fire the valves (at the valve) and see if you have water to each one of them.

    Sorry, yeah all valves will run manually and the master valve is working correctly.

    In that case, I think the mastervalve is not wired right.

    Do a resistance test on the wiring.

    Could be that the clock is not set to turn on a master valve (or pump) with each zone.

    Manually open the master valve.

    If the zones now work, then you have narrowed it down to:

    • Master Valve wiring
    • Master Valve failed solinoid
    • Master Valve clogged exhaust port
    • Master Valve not set on timer

    So your first step is to manually open the master valve.

    Could also have an MV terminal not working on the controller. :)

    With the MV open it still won't run from the controller, all zones will work manually
