I am curious to know whether you tried that test? Did you find anything out?
My next day off is Sunday so I will try it then. If it is the controller is there a certain brand or model you like?
Thanks,
Bob
So today was my first day off since my last post. I started from scratch and ran my sprinklers with water and every zone worked perfect.
Every zone started and stopped as they should.
I then attempted to blow out my sprinklers starting with zone 1. Just like last time all the zones came on at once. I disconnected all the remaining wires to to other zones and still all the zones came on again.
The system being so old I decided to update the controller anyway. I installed a new Hunter Pro C box with 6 zones. Started the process of blowing out zone 1. Same issue all zones came on at once.
I took the cover off and cleaned all the zone valves. Same problem, I shut the flow control off on all the zones and was able to blow out each zone separate. Well at least I am all set for the winter and can attempt to find the problem next year. Again thanks for your input and sorry for my slow reply, The valves are old Toro Quick link valves where you push the wires into the valve
