My tank flush hose has a ball valve where it connects to the RV so I can turn it on or off without having to drag my ancient bones to the hose bib several times. I leave the hose charged all the time, except if we leave the site.
I use a second hose mainly out of sheer laziness. I don't feel like disconnecting the white hose, connecting it to the tank flush, eventually disconnecting it and reconnecting it to the other connector, turning valves on and off several times, when I could spend all that time sipping a cold adult beverage and watching a football game.
