Do your "2 cold low point drains & one hot low point drain" drain the tank when opened with water pump off? I mean materially draining the freshwater, not just the residuals left in line beyond the pump, and not necessarily 100% empty.
I can see my Freshwater tank as it is under bed, the way it is plumbed gravity will take it all @100% to the pump which is about 15 feet away in a lower compartment bay (actually my wet service bay). If the pump is on, then all of the water in fresh water tank will come out, when finished the other water already passed the pump in the fresh water supply lines will back drain & flow out one of my 4 low point lines (2 cold/2 hot). Given I drain the Water Heater separately, I am 100% drained after my blowout @ 40 psi.
