Since the lines will be pretty much level, and I can't 100% say that there will be a significantly "lower" point, could I install the flush caps at the furthest end and then remove the caps in the Fall and blow air thru the main lines? I don't plan on having any spagetti tubes, just the emitters poked right in the main lines. 25 trees, laid out in a grid of 5 rows of 5 trees. The trees are semi-dwarf, and I was planning on two 1 gph emitters/tree. I was going to make a perimeter line, and then "T" from one side to the other to get water to the trees in the middle of the box. Will I have to control the air pressure that I use to not damage the emitters until the majority of the water is out of the line?
