Exactly. My mistake, I somehow missed them last time. But I am not sure that there is any cross-connection between the two pumps that are on as you have drawn? And there is a valve on the cross-connection between the two pumps that are off. Which are exactly the pumps a meant. The 5 l cited as collected were measured from this can, as far as I understand. But it looks like it was an airtight connection to it, why I am skeptical to the function of it. There would be a need for the air displaced by the condensate to get out of the jerrycan. I would have liked to see a second hose go back to the topside of the steam-pipe.
