Default Placement of Check Valves DIY CO2

Hello guys, I had a question about where to place the check valves for DIY Co2. I am going to be using the schematic in this link below.

http://www.plantedtank.net/forums/sh...d.php?t=152916

The air lining in the 2 liters doesn't come into contact with the actual yeast/sugar mixture right? I read it is supposed to be a few inches above the actual liquid. (Please correct me if I am wrong)

This lining doesn't connect to the tank straight, so do I need the check valves between the 2 liters and the separator bottle or can I just place one between the separator bottle and the lining into the tank?
(The lining doesn't directly connect to the 2 liters, so I was wondering why are those check valves needed? Wouldn't I just need a valve between the separator bottle and tank to prevent siphoning of tank water into the bottle?

Thanks for the help guys!
