- 【Heavy-Duty Brass Construction for Long-Lasting Performance】Crafted from thick-walled, corrosion-resistant brass with stainless steel internal components, this 3/4" pressure vacuum breaker withstands up to 400 PSI and delivers superior durability in harsh outdoor environments—ideal for residential, commercial, and agricultural irrigation systems.
- 【Reliable Backflow Prevention Against Backsiphonage & Backpressure】This pressure vacuum breaker automatically admits air into the system when water pressure drops, breaking the vacuum and stopping contaminated water from siphoning back into your clean water supply—making it essential for lawn sprinklers, garden hoses, and outdoor faucets.
- 【Easy Installation & Field-Testable Design】Features standard 3/4" NPT female threads for straightforward connection to existing water lines. No Teflon tape needed—use pipe sealant for a reliable, leak-proof seal. The field-testable design lets you check valve performance without disassembly.
- 【Versatile Applications Across Multiple Water Systems】Perfect for irrigation systems, greenhouse watering, cooling towers, fire sprinklers, and outdoor spigots. Protects potable water sources in compliance with plumbing codes requiring backflow prevention devices in non-potable water connections.
- 【Built-In Freeze & Vacuum Collapse Protection】When installed above ground and properly winterized, the valve prevents pipe collapse during rapid drainage or line breaks by allowing air intake—adding an extra layer of system safety in cold climates.
