i want to add more zones/valves to my existing sprinkler system, but the wires in the underground cable bringing 24V to the various valves, are all in use.
does anyone manufacture two valves that can be separately controlled via one wire? maybe ac vs. dc, or with diodes?
I hate to have to re-lay another cable.
