Hi, I have usually just joined up old tubes to make my windowfarm airlift demo’s and I did not really understand why other people were having problems. Then I did this experiment today pumping water to 18 ft high with a T joint and 2 ft of submergence. (I did it). But there was the blocked tube problem over and over. I had to put detergent in the tubes to help get off whatever grease or coating that new tubes have! Finally it started working but was still stopping at times.
I think windowfarms need to issue an advisory about this. So many people had a similar problem and after a day or 2 it went away. Perhaps detergent is the answer, perhaps washing soda, perhaps dish soap. A few quick experiments need to be done to find the best solution because it really seems to put new people off. Thanks Brian. The new video is at http://www.youtube.com/watch?v=6_88_xUd5Zs
