Perhaps this is a learning moment for me.
Your right, Black should be first. But with this setup, it's important to see if there are any leaks before turning the pump on with black water. If for any reason you need to remove the pump, there will be water between the pump and the valve(s).
I open the grey valve first, turn on the pump to see if everything is working properly. Then I shut the grey, open the black. When the black is empty (high pitch motor noise), then I close the black and flush it out with the grey.
All in all it's a very simple procedure that takes less time then the standard slinky setup.
I purchased the portable unit so that I could take it out to save weight if I felt necessary. It was also on sale at the time by $100, Camping World. It probably only weighs 20 lbs, but every pound counts on the Solara.
