What is the Purpose of a Vacuum Breaker in Faucets
Question:
What is the purpose of the vacumn breaker. When the faucet is shut off, it weeps water out of it still
asked by: Tom I
Expert Reply:
A vacuum breaker is an attachment commonly placed on a bibcock valve or toilet or urinal flush valve, that prevents water from being siphoned backward into the public drinking water system. This prevents contamination should the public drinking water system's pressure drop.
A vacuum breaker typically contains a plastic disc that is pressed forward by water supply pressure, and covers small vent holes. Should the supply pressure drop, the disc springs back opening the vent holes (which let in outside air), and preventing backflow of water.
A leaky faucet is not typically tied to a vacuum breaker.

I have found a full brass fixture with no breaker Item # PF213321. What are the downfalls to not having the vacuum breaker?

Thanks for clarifying Jacob. My concern is that I want to put a on/off at the vacuum breaker, which Im sure would end up snapping after some use. Any ideas for that issue?
