I only have 1 valve/zone, a Rain Bird DAS-075 3/4" and I got the 8 zone Rachio3 so I can automate the usage with my phone. There is a black and red cord coming from the valve that the manual says can be interchanged. I put the black into the common on the Rachio and the red into zone 1, but nothing happens when the Rachio runs a test. Should I put the red cord into the master valve instead? Thanks in advance for any help.

It does not matter which wire is where. One wire should be to the zone terminal and the other wire to common. A master valve is a valve that turns on the water for the zones, etc. I presume that the old controller turned on/off the zone, correct? As far as you can tell, the Rachio is saying the zone is turning on. Do you happen to have a multimeter?
I do not have a multimeter. The valve was previously hooked up to a RainBird ESP-9V battery powered controller.
I tried switching the cords between C and Z1 and it turned on the valve, but didn’t turn it off. This made me think the valve was DC power but after checking, it’s not.

Does the valve only use 9VDC? If so, that might be a problem.
I don’t think it’s DC, the manual says it’s AC.
The controller manual indicates in the Troubleshooting section:
Must use a 9V-latching solenoid (Rain Bird K80920) or other compatible DC latching solenoid.
The valve manual indicates also in the Troubleshooting section:
If fuse is OK. either use volt/ohm meter to check the controller output (24VAC)
Well, I am confused with what seems to be two different outputs unless I am reading it wrong.
@Scott05 - the Rain Bird controller has 2 - 9V batteries. It will be putting out DC voltage.
The Rachio behavior of turning on a valve but not turning it off is classic when Rachio is dealing with DC latching solenoids. Replace the solenoid with a 24 VAC solenoid and it should work.
