Yes, they wear out. By that I mean, occasionally they will trip to off for no apparent reason -- I presume due to an increase in water pressure.
I know a lot of folks will have a problem with my solution, but .... I have done this on most all of my valves and the fix works perfectly and costs almost nothing. I drill a hole in the valve and then use a cable tie so the valve cannot trip unless the cable tie is removed.
The valve can be tripped manually when needed -- cut the cable tie! Then use a new tie as needed!
Simple, easy to do and costs close to ZERO!
Remember, these valves serve one purpose, only. They allow you to shut the water off to whatever appliance (sink, toilet, ice maker, etc) they provide water to. They do NOTHING else.
