Protect tank walls from collapsing during draining
Hayward's all-plastic, corrosion-resistant vacuum breaker allows
quick and trouble-free draining of tanks and piping systems.
Normally closed at positive internal pressure, it automatically
opens and allows air to enter the tank or system during
draining at a rate of up to 300 GPM.
This vacuum breaker has a 3/4" FNPT connection. For mounting
on tanks, you can also solvent weld it in the optional 1-
1/2" Hayward bulkhead fitting, which is sized to accept 1.90"
outside diameter of the vacuum breaker. PVC body with FPM
internal membrane (comparable to VitonT) provides excellent
corrosion resistance. Pressure rated at 150 psi @ 70°F.
