My experience with drip irrigation systems is limited to Arizona where my mother lives. Drip irrigation is almost a necessity there, because of the constant heat. Her system is a mixed blessing. It springs leaks constantly. Animals constantly chew through the hoses. Because of the extreme variation in temperatures (there is a 40 degree differential between night and day), the connectors become lose, from expansion and contraction and often leak. We put cables ties around all the places where hoses fit over connectors, which helps somewhat. Because of the constant sun there, her hoses are starting to decompose from UV exposure (on a 10 year old system), and need replacement. Water is expensive there, so if she is out of town and a drip system springs a leak, it can be pretty costly. Anyhow, it may sound like the system is a total PIA (which it is), but for the most part it works, and I would say 80% of the problems she has experienced have to do with the extreme environment. There are however, a lot of parts to fail.
