Reliable Venting of Tanks and Piping Systems
Hayward's all-plastic, corrosion-resistant Vacuum Breaker allows quick and troublefree draining of tanks and piping systems. The vacuum breaker is normally closed at positive internal pressures. As the tank or piping system is being drained the Vacuum Breaker automatically opens and allows air to enter the tank or system.
