Anyone have an auto shutoff leak detector system?

[John Lanciani]

Interesting, I'd like to hear more about the rational that well water and municipal water would have differing solutions. In my experience a shut off valve is a shut off valve, as long as it's rated for the systems pressure it shouldn't care where the water is coming from.

The system for my well shuts off the electric supply to the pump, the system for municipal water uses a valve to shut off the water.

ETA; the nice thing about shutting off the pump is that no matter where the leak is it gets mitigated (and saves the pump). With a valve, if the leak is on the supply side of the valve it is useless.
