I just replaced a 19 year old Mansfield anti-siphon hose bib with an Arrowhead 456-12BCLD from Ace.

The Arrowhead unit just has the faucet, not the external valve on top, so the anti-siphon valve must be inside, right?

Is this model considered to be good quality?

Thanks.

Actually, by looking at the picture i don't think that particular one is an anti-siphon version, just frost free. I could be wrong-wouldn't be the first time.

I looked into this some more, so I will answer my own question:

They are using a new type of built-in vacuum breaker.
