Let me try explaining my question this way: Baz says drip volume is the same at every emitter, even along a LONG line. Others say drip volume is uneven. I say that when I chain three soaker hoses together and operate them at a proper low pressure (low enough for them to dribble instead of spray) the last of the three soaker hoses does a poor job of emitting. Most of the water comes out the first of the three hoses. This is why I imagined that a system designed to dribble slowly, despite higher pressure (as I think someone said the Rain Bird system does) would in fact deliver a same or similar volume at the LAST emitter along a 200' line as it delivers at the first emitter.

Somebody said these systems can have fairluy LONG lines with all emitters doing their jobs. I think some pressure would be needed in order to accomplish this.
