Well I read the thread at the top of the page about getting into irrigation but it really did not help much. I live in KS and would like to spend my extra time this year studying about the irrigation field and next year getting into repairs. Here is what I know. I spent 2 years after HS working as a plumbers apprentice so I know my way around pipes. From plastic to copper to steel. I know a little about programming a system just from experience in the field. I know how to replace heads and how to position them. My question is what can I study to increase my knowledge? Im looking for websites or books. For now I just want to do repair for my current mowing customers and maybe down the road do installs. Start slow for now. I checked with my local community college but they dont appear to offer anything related to it. Also what state office would I need to check with? Dept of Ag? Thanks.
