Yes I do agree it is a simple way to flush tanks.
but even with a vacuum breaker it is possible for bacteria from the black tank to find a way into your fresh water system.
To be safe ALWAYS disconnect from the Black tank ALWAYS after flushing
One simple way to do that is with a set of Quick Connects. You may use the same hose (not recommended) but you simply move the hose from one to the other to flush.
Dump the Y
I use a Y, and a short hose with a quick connect DISCONNECTED when not in use.
