I brought back a Xerigation manual from Rainbird, when I was visiting California, back in the 20th Century. It's very detailed, as might be needed by agricultural usages. What I'm wondering, does anyone actually install any of this 'textbook' drip irrigation? I mean the type with discrete emitters, color-coded for gallonage, with quarter-inch tubing connected to the emitters' outlets, with the end supported above ground, complete with 'bug cap' The above-ground termination would be essential for an ag install, I would think, because someone would be visually confirming that the system was working 100 percent. Cash crops, and all that. The one thing that the manual recommends, which I rarely see, is the application of a full six inches of mulch covering, so that the emitters don't get crunched by foot traffic. That runs into money. An alternative to the color-coded emitters, would be the multi-emitter devices, which would allow common pipe (PVC, I'd expect, for critter resistance) to be used for the drip main, and multiple outlets could be dedicated to a single plant, if it needed more water than its neighbors. The main could also be buried, and the mulch requirement avoided. Rainbird had a display rack for all this varied drip stuff, and I only saw one distributor in these parts with one, and it didn't last long. So, anyone here do their drip by the (ag standards) book?
