Here is a short explanation of how I built my ATO. It works great, it's worth the time to save money, trust me.

Pretty ingenious! The old water cooler jug method for ATO....no pumps, no sensors, no electricity.

The only issue I see is that I go through about 1 to 1 1/2 gallons a day. I'd have to top off that 20 ounce bottle you are using too many times!

Nicely done video.
