I got around the dripping mess by buying a 3' hose and shutoff valve that I leave attached to the inlet. This way, I can drop it out of the basement along with my city water hose, connect my black water hose to the end with the shutoff valve, turn on the water, open the shutoff valve and flush! When I am done flushing, I close the black water tank valve, allow more water into the tank (maybe 3 gallons?) and shut off the short hose shutoff valve. Disconnect the hose from the short hose shutoff valve and you are done! no back draining, no mess, no dripping water and it is ready for the next time you need to flush. And a dangling 3' hose (permanently attached to the flush fitting) does not take up any space in the wet basement.
Great solution..Thanks!

So of course there is less pressure and water in this video then I normally see after I remove the water hose. Unfortunately, it was only one take for my wife since she has no patience and went back inside.

I would say normally there is at least double the amount of water and considerable more pressure. It was about an hour after I had actually flushed the tank that this video was recorded. My wife was on a business call so I had to wait until she was done.
