I made another video and basically I ran out of pipe and ladder and because of that I couldn’t pump any higher but I am curious. How high can you go? I went 13 ft but there was no problem whatsoever pumping that high! So, maybe, if you have a 2 story house or an available high place you could find out how high it is possible to go? So the contest rules are in the picture below and in a video
(You might get some extra hints and ideas if you watch the video)
Basically you use your aquarium air pump, and a T joint set at 2 ft below your liquid reservoir height.
So the rest of the post is from a couple of days ago and has a little different version of the video. (I am too Lazy to write a new post)
I made a new video about the pulser pump and Eileen suggested that a “pulser pump nano” (a smaller version) might be useful. The pulser pump is my little “invention” from over 20 years ago. Anyway, I no longer live near a river so I cannot do a nano. But because of my involvement in windowfarms, I can at least test how high a tiny pulser pump can pump. Today I used the T-joint method and an extendable ladder to go pretty high. With an aquarium air pump and 22 inches of submergence, I pumped to 13 ft high today! I bet it can go a lot higher but thats it for me.
Here is the video (which may be of some use to windowfarmers)
