    What is the point/justification for the 5 foot coil of unused tubing at the bottom?

    1. When the water line is too short, it’s too easy for air to flow back into the reservoir bottle rather than up into the lift tube, and you just get an air bubble generator. You have to convince the air that going up the lift tube is easier than going down the water supply line into the 1 liter bottle.

      Raising the height of the reservoir bottle accomplishes the same task, since gravity helps, but I didn’t really want to have any more ugly soda bottles hanging in the window.

      Another option would be to have a check valve on the water supply lines, but those are considerably more expensive than the 5′ length of hose.

        Plus, check values can break.

    Thank you for this diagram! I found you by way of one of your windowfarms comments. It helped me solve the escaping air bubbles problem. I’ve got the first column up and am trying to figure out how to add in a second column if I split the air flow tube.

    Great idea, thanks. I am using a larger water tank so I think I will try your idea. Where did you find the T-joint? T think that you live near Toledo, the same as me.

    Followed the link over from your posts on the Window Farm site and I wanted to say thanks for the pointer to the aquarium gang valve. I now have 5 columns going off 1 small air pump.
