Currently, I'm just plumbed in one leg of the IBS. At the end of the day, there is a little bit of water trapped in the opposite leg but we just "lift the leg" and drain it :). I think that decelerating and coming off plane pushes any leftover water forward and then at least half of that drains, I'm kinda surprised how much does drain - we probably only have a couple of gallons of water left. I've been meaning to add a T to the other side but it hasn't been enough of an issue to move it up in priority.
