OK, remember no dumb questions...part 2
I have been unable to find any info on this in the manual..
How does this work....?
I put the hose on it but just got a LOT of back pressure...
Bad picture, but I am sure somebody will recognize..

Sewer flush

Here is the bigger area..

Water area

Thanks again...
 
After emptying the black water tank, connect a hose (not your drinking water hose) to the fitting and turn on the water.  This will spray water around the tank, flushing out any remaining solids.  I close the drain valve for a few minutes to build up some fresh water in the tank, then open it to flush out the remaining solids.  Repeat as desired, I use a clear section of drain pipe and watch until the water coming out is nearly clear.

You will get some back pressure but should hear the spray nozzles at work.
 
If you don't hear the water running, it's possible that the check valve is stuck closed.  If it's working, you should easily hear it and see water draining if you use a clear drain extension.
 
Mine takes quite a bit of pressure to work. When we first had the coach I thought the tank flush wasn't working.
