We've been getting these insurance offers from the local water company to the effect that the service from the main to our house could fail at any time and that we should pay a few bucks per month to avoid repair costs.
My kneejerk is that this is a cash cow for the water company.
This neighborhood was built in the mid fifties. I've never heard of anybody's service failing.
Is there an average lifetime for this stuff?... Or are there different constructions/water compositions that make comparison impractical?
