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.
I understand all of this but when there is pressure on the "Y" before and after flushing. There is a "Snowballs chance in he!!" that would happen.
I flush my tanks for 10 minutes at a time and the black get's it twice.
With your system the water that's left behind the VB is draining back and out your "Y" connection. mine can't drain back because I shut off the valves when flushing is complete. There "COULE" be bacteria in that water.
I like my system better!
The VB's and now PVC fittings are around 3-4' above the tanks.
