Swedish Steve,
You say that the CTR tank water scavenge pumps are ALWAYS running.
But you also state that their "power supply" comes from the tank booster pumps outlets.
My question is then - how can the water scavenge pumps run if there is no fuel in the CTR tank?
I suppose that they will shut down automatically, when booster pumps stop producing pressure due lack of fuel (at approx. 900 kg) - you see what I mean?
