Let's try to think this through.
Why would two grey tanks be plumbed into one discharge valve?
This would mean the plumbing that connects the tanks upstream of the valve would have the potential to leak. That is why you will always find the discharge valve mounted onto the tank. If you have one valve, you have one tank.
Another clue is your listed grey water capacity. If you have two grey tanks, your grey water capacity would be up around 60 or more gallons.
