So, here's how it works. The Flush King is valve A, Black Tank is Valve B, Grey tank is Valve C.
1. Open A and B initially and let all the contents of the black tank completely empty.
2. Close A (Flush King), and open C (grey) and let it back flush into B (black). Wait 10 seconds.
3. Close C (Grey)
4. Open A (Flush King) again and let the black tank drain again until nothing comes out any more.
5. Repeat until there is no more grey water left.
When I first woke up this morning, I was hoping someone would post pics of their poopy water. Wishes do come true! :)
So how big are your holding tanks? My tanks are pretty close in size, so your procedure wouldn't do much more than clean the very bottom of the tank. What I do cleans the entire tank since I know the black tank gets filled before re-flushing.
For me, when it is time to flush, I turn the valve for the in-tank black tank rinse on. Then I open the black tank valve, then I close the valve, let the tank fill up again, then I pull the valve again. Rinse and Repeat. Usually after the 2nd fill, the water is clear. Then I close the black tank valve, wait a minute or so, then turn the water off to the black tank rinse.
At the end of the season, I rinse and repeat a few extra times.
