I am not following your description. I have yet to drain the WH or FW tanks down here, but would like to go see relatives in Philadelphia this winter if I thought we could winterize enough to do so.
I thought there is a plastic drain plug that you unscrew and the water comes out (hopefully missing some heater wires and components just below).
Are the little pull rimgs the way to drain the FW tank; there is one right by the tank hose under the dinette? There is one (maybe 2) more on the cabinet floor under the kitchen sink near the hoses in fron of the WH.
Could you add more info on Philly and the drain questions?
