Even had to replace the valve seat twice, the valve body remained.

If the vacuum breaker is causing the leak, you can cut it off and replace it with another vacuum breaker and still be legal. You can screw a new vacuum breaker on and not use the set screw. The problem with the set screw is that it is designed to be non-removable. So, when you screw it tight and then try to remove it, the top part will break off making it almost impossible to unscrew.
