But at the turnover (start level) you want the bottom of each tap's turnover to be about as high as, or higher than, the top of the next lower one's, so all the flow goes into starting one siphon, rather than getting distributed over several and thus never sucking the bubble out of any of 'em. Similarly you'll want SOME difference between the height of the lower ends so they "suck out" cleanly and one at a time. [ Parent ]
