Ok so just redid a 7 valve system that had them all crammed into one box. Yes 7, rainbird 100PEB in one 20" valve box. anyways, split them up into two boxes, wired it all up and replaced two of the valves that were having issues. The homeowner did not want to spend the money for another 5 valves so we reused the others. Well, got everything connected, tested the system manually and then with the controller and everything seemed fine. Well i get a call from them yesterday and the system is stuck on. I get over there and one solenoid is making the clicking sound constantly so i shut the controller off. i figure i had a few extra solenoids on the truck so i just swapped it out and tested it again. No problems, no clicking, turned on and off without any issues. Well now they call me again at 11pm saying its stuck on again. Any ideas what this could be? Im stumped and thinking it might be with the wiring? idk, but any help would be greatly appreciated. Thanks.
