Pressure vacuum breaker (PVB) and atmospheric vacuum breaker (AVB) are both designed to relieve backflow1.The main differences between PVB and AVB are12:PVB is designed to be under constant pressure, while AVB is NOT designed to be under constant water pressure.AVB opens when the pressure drops to atmospheric pressure, breaking the vacuum and opening the poppet.AVB is less dependable than a reduced pressure zone valve, double check valve or other backflow prevention device.AVB costs less money and does not require yearly inspections and testing.Learn more:✕This summary was generated using AI based on multiple online sources.
