Finn, did you use dish soap or some type of 'water wetter' to kill the surface tension of the water? I've also used water levels and found that using a larger pvc hose on the ends than is used on the center worker pretty well. I think it has to do w/ the mass of the water in the larger hose easily overcomes and friction in the smaller middle hose. Also the smaller hose is usually cheaper. Oh.. and it then reacts slower so it doesn't occilate back and forth for-forever.. [kind of a dampening effect forcing all that water through the smaller hose].
