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...

Appreciate the feedback ... but considering how many different varieties of RV plumbing options there are ... still unclear just exactly where did you put the hose to flush out the black tank .... was it screwed to a dedicated and labeled receptacle for black tank flush ... or something else? Also, make / model / year of your RV might be extremely helpful for some of us to try to figure out just what was going on ....
