I've been doing primarily lawn and landscape maintenance for the past 4 years. However, the past few days i've been learning about Winterizing sprinkler systems. I've known for some time the components in a sprinkler system and how they work together to get that wet stuff onto the green stuff. The Sprinkler Tech i've been working with has been complimenting me on how quick I leran and that I seem to have that common sense factor that some employees never attain. He's wanting to train me to be another service tech next year. I know it's better money then lawn maintenance and the demand is growing greatly. So I'm considering it. I'll get backflow certified and all that stuff but I was wondering if any of the manufacturers make a how-to book or guide that begins to explain basic and indepth service of irrigation. I figure I can be Tim's "trainee" all winter and most of next spring or i can read up and get an idea of whats goin on before we work so i can catch on quicker and be ready before start-ups next year. Any info or insight would be great. I'm in Wichita, KS so I dont know if there are any training programs here. but for now I'm doing blow-outs for the next 2 weeks or so. Thanks guys!
