I've never thought about doing that, as we turn on the pump and leave it on while at the campsite. Every once in a while it has a very quick cycle to bring the pressure up, as it fluctuates with heating up, and cooling. I would think you would need something like a three way switch arrangement like at the top and bottom of the stairs, like in a house. Maybe there's someone here who's done this.
Every day's a learning experience, though sometimes not what we expected.
