What does a vacuum breaker do on a flushometer?
Flush-valve vacuum–breaker repair parts are components for replacing the vented sleeve that stops backflow to prevent contamination of the water supply.

Backflow preventers prevent the possibility of pollution in the water systems. Thus, the good water does not come into contact with the sewage or other pollutants. This is the same function that the vacuum breakers play. Therefore, in essence, vacuum breakers are types of backflow preventers.
What is the most effective type of backflow preventer?

How does the vacuum breaker work?
How It Works. A pressure vacuum breaker consists of a check device, or check valve, and an air inlet that is vented to the atmosphere (open-air). When the air pressure is greater than the water pressure, the vented chamber opens and breaks the suction effect of the low pressure, thereby preventing the backflow of water
Does a vacuum breaker prevent freezing?
I call this “two wrongs making a right.” It’s certainly not a reliable method of preventing freeze damage, but it does seem to work. Vacuum breakers complicate things . The problem with external vacuum breakers (aka backflow preventers) is that they don’t allow all of the water to drain out.
What causes a vacuum breaker to leak?
The culprit is often a leaking pressure vacuum breaker (PVB). 1) Wear and tear: Over a certain period of time, things just wear out. The same goes for a PVB. Undergoing normal use of pressure over time, a PVB is susceptible to leaks.
How does a vacuum breaker for a hose bib work?
Hose Bibb Vacuum Breaker
