Vacuum Breaker (3/4", PVC)
GENERAL DESCRIPTION
Reliable Venting of Tanks and Piping Systems: Hayward's all plastic, corrosion resistant Vacuum Breaker allows quick and trouble-free 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 open and allows air to enter the tank or system.
Advanced Design for Fast Draining: These vacuum breakers allow a tank or piping system to be drained at the rate of up to 300 gpm. For even faster draining requirements, just install additional vacuum breakers. For instance, three installed on a tank would allow a drainage rate of 900 gpm with properly sized drains.
