The last flush I do before we leave a campground takes me 20 minutes or so. After the first dump I then close the valve while the tank flush is running to fill it so it refloats any solids, close it for maybe a minute or 2 max. It does the trick and I repeat that 3 to 4 times. I hate leaving "stuff" in the tank when it is sitting in the yard. If your wife is like mine and uses copious amounts of TP then consider doing this to get that paper out. The flow has stopped before with a gob of paper waiting to be pushed out. The tank bottoms are flat so it takes some patience but like I say, better out than in.
