I will have to disagree as nationally certified ICC residentail plumbing code inspector with Gary Beaumont’s comments regarding ‘replacing’ and ‘rebuilding’ atmospheric type vacuum breakers.

While such ‘vacuum breakers’ might be able to be rebuilt, they will certainly lose their listing and labeling by their manufacturers if so done…and therefore become an illegal appliance if continued in use unless recertified by the 3rd party listing and labeling agency.

That said, the ONLY correct action is this case is to replace the entire hose bibb completely so that the new one is listed and labeled for its use.

‘Rebuilding’ is not code compliant under the IRC plumbing code provisions even in Florida unless Gary Beaumont can show otherwise.

What I see is a code violation and the entire hosebibb assembly needs to be replaced not “repaired”…
