|For running irrigation lines up a slope... I don't think you have to put pressure regulators at every "T." It's just the drip or soakers that can't go up/down-hill (unless they're teh pressure compensating type). Get out your electrical diagrams from high school physics... you can connect pretty much all you want to IN PARALLEL without building up too much resistance in the line... it's when you start connecting things in SERIES (end to end) that things can go haywire in a hurry.
When you run a supply line out from your faucet, you can put X or T connectors along that line and then run 50 foot soaker hoses (or drip irrigation lines) out from each connection. You could do that with hundreds of feet of soaker hose, as each section connected to the supply line is in parallel with the other sections. But any individual sections -- any of the soaker lines going out from the supply line -- can't be more than 100 feet long or go up & down hill more than a couple of feet in elevation. You could connect a 50 foot soaker to the supply line and connect another 50 foot soaker to that one (in series, see?), but that's the limit.
At least, that's my understanding and the easiest way I can think of to explain it... even if I was awful at physics!
