An elderly friend showed me a letter she got.
It was a very official looking "notice" about the water line to her house. It looked like something that was from the local water utility, but it was actually an ad for insurance for problems in your water line.
It was very carefully crafted to make you think it was official and that it was something you should have, although if you read the fine print, it did say it was not connected to the utility and wasn't necessary.
Stuff like this really gripes me. Warn any vulnerable loved ones or friends you have. And don't fall for such things yourself.
I wonder how good this coverage ends up being if you ever have to actually use it?
