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.
Why is my vacuum breaker leaking from the top?
If water flows the reverse direction, the pressure vacuum breaker will open and prevent the water from going back into your house (and you drinking it). So if something is blocking the O-ring from making a good seal, then you could end up with a leak.
