Just called to look at timer settings last week on a home built 2 years ago. they were using 30% more water than Apr May Jun of last year. The lawn tech had turned off the rain sensor. Not the brightest idea considering the rainy summer , and Zoysia being very susceptible to fungus.
9 out of 10 problems I find with timers and sensors, were inflicted by a person that thinks they know what they are doing . Lightning takes up most of the last 10% w/ mechanical failures not absent, but quite rare.
By the way, I have 35 years of irrigation experience... residential, commercial, agricultural and golf course.
