I was called out once by a landscape contractor who relied on his employees to do any actual work, including irrigation design and installs. His customer was complaining about high water bills and he wanted me to check for leaks. It was all programming errors. 12 zones, every day x 30 min per day. Mowers left wheel ruts and mushrooms abounded.
