I have a solenoid with it's own valve connected to the main water supply, where I turn the water on and off. I have a separate valve on my sprinklers in the front yard. I was told each valve should be wired to a separate station. My Orbit timer only allows to turn on one station at a time. When I turn on the station wired to turn on the water supply, I can't turn on my sprinklers, what can I do?
