One leg of my sprinkler system's flow switch that triggers an alarm failed due to getting wet. A contractor wanted $1200 to replace the switch. Gee, I take it apart and find there's a diaphragm type damper to prevent it from being touchy. The spring on the diaphragm is bound-up with white zink type corrosion preventing the switch from operating. A bit of cleaning and lubrication and it's back in service. When I asked the ADT repair guy and the sprinkler contractor about servicing the switch rather than replacing it, the both looked at me like I was nuts! "Oh, those switches can't be repaired, that would be sacrilegious! And, it's obsolete and we have to open up the 8" pipe to put a new paddle in...and chances are we'll break something." WTF!!! Does nobody repair stuff anymore? This was a VERY simple, straightforward job I did at my desk in 20 minutes.
