Next on the list is the yard; it was wilting in a dry June summer. This time, the controller was “blown up”; you could see blackness around the electronics controller, and its door blown open, and its surge protector fried. Something slightly less dramatic occurred a year ago, and you can’t really get old fashioned mechanical controllers any more (that had run the irrigation system for so many years). I call up the contractor who had installed it, and ask them to come fix. He installed a new controller, but was completely incapable of figuring out why 1/4 of the zones wouldn’t work. The guy they sent had no idea how to use a multimeter to debug the problem. I got to teach him how to use a meter, to figure out the common on that cable was open causing all zones on that cable to not work. (that cable went near the tree that came down in the storm when the lighting struck; the two may be related). And then I taught him to do a binary search to determine which segment of cable was damaged… Of course, this defeats why you call repair people in the first place; one might hope you don’t have to teach them how to do their job. He should have been paying me for the lesson in repair; rather than me, paying his employer… After much hassle and a day of wandering around the yard, water was flowing again (though I still have a few zones to fix).
