I have a Rachio 3 12 zone connecting to a 12 zone drip system. I have a 12 zone manifold with 12 individual solenoids. What is the best way to connect the 12 common wires to a single common wire connection on the controller?
Usually all the solenoid wires are joined with a waterproof wire nut at the valves, and a single common wire send back to the unit.
Thanks for getting back to me
