Hi! I’m Mr. Greensman. Thanks for stopping by.

I Have been working with, maintaining and installing commercial and residential landscaping and sprinkler systems for well over 20 years.  The one aspect of my work that I have found to be increasingly frustrating is the lack of tool and resources for sprinkler installation and repairs.  What I have strives to provide is a set of tools to help the sprinkler installer/repair man to save money and time.  I have been testing this tool for several years in the commercial and residential field.  They have saved me thousands of dollars in time and unforeseen likely complications.  As I state in the Calculators, these are the calculations I use, and the installer needs to use them at their own discretion.  In an attempt to provide these formulas to everyone, I have spent countless hours learning to code.  This site and the coding that went into the calculators and formulas came from my experiences and research over the past 20+ years.  However, there are aspects that may not work in your environment, my experience is limited to cool season turf.  

Feel free to contact me, I will make every effort to respond to questions, but keep in mind that this is site is maintained during my time off as I intend to keep it an entirely free service.

Mr. Greensman
