How do YOU dump your tanks?
The normal (I think) dumping sequence is open valve black water tank and dump. Close valve black water tank. Open valve grey water tank and dump. Close valve grey water tank. Here's what I've been ...

I open grey first to check for 'leaks' then close it
Then open black...run flush or not. Not a every time occurrence
Then a close my downstream added extra valve and open both grey dumps
Greys backflow into black and then I open my downstream extra dump valve and let everything completely drain.
Close off dump valves -----3 tanks and the 1 extra
Add a few gallons back into black and stow hoses/adapters.
Unless using a dump station..then I just dump them all..every valve open and get it done ASAP. Add some water back to black/stow hoses etc and be on my way
But if somewhere that like my sisters place........Macerator. Pump it one tank at a time 75' to cleanout with a 2' rise. Black tank first then both greys and then clean water.
