If both tanks use the same drain. Put a twist on valve on the outlet and close it.
Open both tanks and they will equalize themselves.
The water levels will equalize. Above assumes both gray and black tanks are installed at the same level in the rig. A higher tank could drain all its fluid into a lower tank. My tanks are hidden and I don't know their relative heights. I'll open my tank valves separately as I don't want to risk chunks of sewage getting into my gray tank.
I agree the tanks need to be at the same level.
90% of the time they are at the same level. The frame is only so big There is not room to tier the tanks on various levels.
The grey tank will typically be full vs. a relatively empty black tank when you attempt to equalize. Opening the grey first will send grey water to the black tank. Since the grey is full it will not accept any water from the black. Typically its a simple process with little risk.
