I just insatlled a 4 zone rainbird controller. After install I manually turned on each zone and all is well. I programmed it and it worked fine. I noticed today (a few weeks after install) that only zone 1 works. The controller shows it is changing zones but when zones 2-4 are on the zone does not work. No water at all. I think I have multiple valves I see 2 boxes (1 on each side of the house). Anyone help me get started on troubleshooting this? Thanks Frank
