as a propane tank can and will let off pressure through the valve.

In context, this is a very misleading statement.
The only time a tank will bleed off pressure, is if it some how got over filled, which is near impossible in recent years w/ the use of OPD valves. And even then it will only bleed off if not being used, and even then only if day time temp is rising. A tank will NEVER bleed off while propane is flowing from it.
