2004 Safari 28ft grey water & valve location?

[richpin]

Does anyone know the location of the grey water tank and release valve? I haven't been able to find it and I'm afraid it might be full. There's very little info for this year Airstream and can't find the correct manual either.. This is my first trailer so I'm still learning..

There should be a valve on each side of the connector for the dump hose. Looking at the connector, the black valve should be in the read (right) and the grey would be on the opposite side. You can follow the pipes back to the tank location.
