Edge, looks like a cool system and easy to set up. Is it? How often do you have to add more water and restart the system? And is the check valve necessary?
Thanks,

It's very easy to set up. You don't have to worry about the Kalk clogging any valves. I probably fill the container every other day, just unscrew the top and pour your top off solution inside, screw the cover back on tight so that it makes a good seal. Blow hard into Tube A and away you go. Takes less than five minutes.
I tried this without the check valve and it didn't work too well, I don't think enough suction was being created in Tube A without the check valve. What prompted me to try that? I'm not sure but it works. This is just the prototype, looking back I would have rather used something more ridgid and air tight to begin with. This works, and works well, but there's always room for improvement.

Peace

try putting a clamp on tube A or the other end.

so it ll hold water and not lose it when you open it, then put cap back on, put underwater and unclamp it.
