Never needed a vacuum breaker b4, why now? Seems an unnecessary gimmick/gadget to me. Jmho.
As for code requirement, wonder which politician's brother made millions off manufacturing of this thing? ������������

The purpose for the vacuum breaker is to prevent contaminated water from backing up into your house. For example, suppose you connect a hose to the spigot and then put the other end into a bucket of toxic chemicals. Or, you have a contaminated material inside the hose. Then, you have a leak or a pressure drop inside your house. The reduced pressure could suck contaminated water into your house. If you notice, none of the faucets in your house have a threaded hose connection, and all of the faucets discharge water above the sink or tub rim. This prevents water from backing up into the faucet.
If you want to prevent getting soaked when you turn off the spigot, the easiest way is to buy a secondary brass or plastic valve that will screw onto the spigot, and just leave the spigot with the vacuum breaker open all the time.
