Recently I purchased a quarter inch water supply hose for the ice maker in a refrigrerator. I was surprised to find the hose has a "burst protector" built into it. How convenient are these things? Do they trigger accidentally - such as when a plumber (or the city) shuts of the main supply and then turns it on again? The directions say that the burst protector is reset by disconnecting and reconnecting the hose. Is that really the only way?
