Where to install an atmosphereic vacuum breaker for my fire pit spigot
I have always put a vacuum breaker at the faucet. It would be silly to put it at the house, the water would drain from the line every time turned off if properly installed. The vacuum breaker prevents a hose from sucking up ground water contaminating the supply. So as long as the breaker is at the faucet or part of the faucet and it is higher than the outlet you would meet the reason for the vacuum breaker in towns I have lived That were connected to city water this met there requirements.
