Mods please don't delete this because I mention a specific trade magazine here. In the latest Lawn & Landscape magazine there are 2 good articles on irrigation - finally. I got tired of the articles on what type of heads to use, why use a valve box, how to design a system for the millionth time. But these 2 articles actually interested me. One was on whether you should do installs, service and repairs, or both. All we do is service and repairs so it was good to here other reasons for and against it. One good point was that overhead for service is much lower than installs. No trenchers, pipe pullers, boring machines, bigger trucks, trailers, labor (many install companies have lots of entry level laborers, big shop, etc. The other was on how to charge accordingly for service and repairs. Although I never went through the technical aspect finding what I should charge, I am charging just about what the author describes in his scenarios. A few of you on this site pushed me toward the service call fee a few years ago and it has paid off. Thanks. I recommend these two articles for all you irrigation guys/gals (any irrigation women on this site? That could be another topic as well).
