In general I agree that drip stinks, but not for all the same reasons. The biggest issue is that 90% of it is not installed correctly. HO's don't know how pressure compensation, water pressure, and water volume play a part in drip. They go into their local home depot and start buying parts and slap them together haphazardly. "I can do my whole property on one zone at different elevations." Drip also causes saline build up at the point of emitters, especially because they aren't moved. I read an article about redwoods planted in landscapes are distressed in 5 to 6 years because of saline concentrates directly located below unmoved emitters. BUT in my area drip is part of the irrigation business like it or not. In spring I get a lot of service calls from people that had their drip installed by a LCO and it is failing after being installed for a few years. Drip is planned obsolescence that requires yearly maintenance, especially because HO and some contractors by the crap parts.
