Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

If you have two gray holding tanks they each have a valve and don't dump together. Look for the other valve.

Where are the separate valves. We know where two valves are but there is no water in the main grey to empty even though there is grey water backup in the shower and the kitchen sink

Why are the two most used water going to the small aux tank. And the big main grey is always empty
