Hose bib vacuum breaker acceptable backflow prevention?
Back when I bought my house, I believe the inspector mentioned something about the outdoor spigot not having any backflow prevention. After doing some searchign online, I found out a hose bib vacuum breaker which I just screw on my outdoor nozzle. Is there any reason why that would not be a satisfactory backflow prevention device?
In my mind, I imagined something integrated into the plumbing, but that was pretty much a guess.

Those screw on types are fine. Alot of people remove them when they fail. Keep a couple on hand for when they do. They are for your saftey and pretty much code every where that I know. Keeps you house water from getting contaminated if there was a pressure loss in the home. And of course the hose bib left open, and the hose in a puddle of water.
It seems like it cant happen and is rare, but it could.

But don't break off the setscrew! Unless some city inspector requires it...and even then I'd try and put an allen setscew in and remove it after it's inspected.
If you break off the setscrew, it's a royal pain to replace it when it fails.

It's not the hose thats the issue...it's the possibility (as Mike outlined) that contaminants can be drawn back into the water system.
My parents used regular garden hoses for filling their travel trailer tanks and connecting to campground water for years. None of us ever got sick.
But the regs aren't really to protect US, it's to protect the neighbors and municipal water system...though the odds are VERY long, the cost can be really bad if it did happen...especially in our litigious era.
