While using my black tank flush
For the first time it filled up the fresh water tank!!! There is no other valve to turn on-off so what gives? I’m traveling today ( yes I drained the fresh water tank). Look forward to your replies...

I suspect Chris3403 likely nailed the problem. Easy enough to mistakenly plug the flush hose into the city water inlet if they are close to each other and operator not paying enough attention. Still, since the OP has not responded with more specifics we are all left to just guess how that could have occurred.
