Also, always use my analogy that a sprinkler system is just like a vehicle. There will always be repairs and upkeep as there are moving parts, electrical systems that fails, routine maintenance just like changing oil, etc. Plus there are always upgrades to make the system/vehicle better, more efficient, and more shiny! Maybe that's my next calling, creating some unnecessary BLING for a sprinkler system. Something to shine it up, but does absolutely nothing.
