A friend's house was designed by an architect to be his own house, about
8 years ago, until he sold it last year.It has all kinds of gadgets, including a generator hard wired in, solar panels in the back yard, alarm installed when the house was built, Rinnai hot water (that I didn't understand), two big breaker boxes, only half full but still with 45 breakers total,
Probably some garden faucets were hiding behind bushes, but the one on the patio was a pipe, almost an inch in diameter that came out of the wall one inch and then turned downwards. That part was 4 or 5 inches long with a ball valve in it. And not the standard garden threads on the end of that. Despite that there was a garden hose not connected to but right next to this spigot. (I wish I had looked at the ends of the hose.)
What was I looking at?
My friend told me she thought she had freeze-proof garden faucets but she must be totally confused. Her pipes didn't burst last winter, but future winters may be colder.
