If you saw PBS "Ask This Old House" the other week the plumbling
expert showed a rod for low ceilings that came in sections held
together by either a chain, rings, or a metal cable, not sure which
now. But it avoided having to empty the tank to tip it.
BTW I don't recall if he used teflon on the thread. Would that make
sense or it wouldn't matter?

I suspect Teflon might negate the electrical path that handles the
corrosion.
