2016 dynamax force bh black water tank flush?
I finally took it out for the first time, and afterwords I emptied out the black water tank and then hooked up a hose for the flush system it has. It's supposedly has sprinklers inside he tank to rinse it out. But when I turned on the hose, I could not hear water being allowed into the tank, I waited 15 min, and during that time I was looking for switches or buttons to press to allow it to do this feature, but found nothing.
Anybody out there used this feature? Any advice would be gratefully appreciated.
