I also don't like the anti-siphon spigots. Had the exact same ones and nothing but trouble with them. Just had the plumber replace all of them for leaking profusely. They freeze and break, then leak everywhere including back into the crawlspace and down the face of the house. Only one of four wasn't broken, but I went ahead and had it replaced too because it was just a matter of time. House was built in '07.
I imagine anti-siphon spigots are code, even though he has a well. On city water systems that often extend out into the country, it is required so some idiot won't leave a hose hooked up with the business end stuck in some contaminated puddle of something while some nearby water line is drained for maintenance. That's a long straw but it could happen. Out in the country on a well, they really shouldn't care if a homeowner poisons himself, but the theory is that as suburbs develop the near by city is usually petitioned by the residents to get city water and sewer. The recovery cost of the extensions won't be recovered by the cities for many many years if ever, but they have to do it. Then they move the city limit sign out beyond the project in some cases, usually only if there is industry or dense population, to get more recovery from taxes.
Anti-freeze spigots are a different topic. That is related to local climate. Up north we have anti-freeze spigots where the shutoff plug and washer are as much as 2' back inside the house.
In the Carolinas they may not be a normal install, I don't remember.
Funny thing about water. I was stationed at Myrtle Beach AFB for a few years, many many years ago when my kids were real little. The water system there had an excess of flouride so all the mothers were instructed not to give babies and little kids the base water as it might blacken their teeth. My kids did drink some of the base water along with bottled water, which was almost an unheard of product in those days. Anyway, they have never had a cavity and their teeth are as white as normal some 40+ years later.
I am glad to live far enough away from any city that has water and sewer to never have it out here. The taste of chlorine in city water is enough to keep me from drinking it.
