Plumb every thing back to low points and drain there
My cabin is off grid and in the boonies and I have 4 valves to drain the whole system inside and one in the well it just takes some fore thought.

That's not a bad idea... run your supply lines with the same kind of slope as your drain lines.
It still wouldn't hurt to have some way to blow the lines out.
