I am a Louisiana state licensed landscape contractor and have been subbing out the irrigation jobs. I am interested in learning the installation myself but as you might know, no one wants to really show you how because it takes away their income which i understand. I cannot go to a class far away and learn. The irrigation supply stores here ( 2 of them ) don't offer classes either. Any books or ideas from any one would be appreciated.As I said, I am only interested in my own lanscape jobs that need irrigation.
