I bet you're one of those posters here that say that water is all you need for a black tank treatment.
I try to avoid absolute statements, but after using tank treatments and then reading here, have found that "just water" is usually good enough.
...Use a twist on valve to give the black tank a quick rinse from the gray side???
That sounds reasonably efficient and another potential use for those nifty screw on valves.
I was more focused on the time we had water but no sewer and filled the gray side one day too soon.
