Zurn Wilkins 720A Pressure Vacuum Breaker (1-1/4 in FNPT) - 114-720A

• Reliable irrigation backflow protection: The Zurn Wilkins 114-720A 1-1/4" Pressure Vacuum Breaker (720A series) is designed to prevent backsiphonage in high-hazard, non-potable systems like irrigation and outdoor water supply lines.
• Complete protection design: Includes an approved check valve, vacuum relief valve, and test cocks, ensuring proper atmospheric protection when system pressure drops.
• Durable all-bronze construction: Built with a cast bronze body and corrosion-resistant internal components, making it suitable for long-term outdoor exposure and light freeze conditions.
• Consistent performance standards: Rated for up to 150 PSI working pressure and typical operating temperatures of 33°F to 110°F, matching standard irrigation system requirements.
• Installer-friendly layout: The 1-1/4" FNPT configuration and centered test cocks improve installation flexibility in tight mechanical setups.
• Code-approved and widely accepted: Meets major certifications including ASSE, CSA, and USC Foundation approval, ensuring compliance for regulated installations.
• Best fit use case: Ideal for residential and commercial irrigation systems where health-hazard protection is required but full RPZ-level protection is not necessary.

Q: What is the Zurn Wilkins 114-720A 1-1/4" Pressure Vacuum Breaker (PVB)?
A: The Zurn Wilkins 114-720A is a 1-1/4-inch pressure vacuum breaker assembly designed to prevent backsiphonage in potable water systems, especially irrigation and other high-hazard, non-potable applications.

Q: What does it protect against?
A: It protects drinking water systems from contamination caused by back-siphonage (negative pressure pulling contaminated water backward into the supply).

Q: What applications is the 720A series used for?
A: It is commonly used in irrigation systems, commercial plumbing, and outdoor water lines where backflow protection is required for health hazard situations.

Q: What are the key features of the 114-720A?
A: It includes an internal check valve, atmospheric vacuum breaker, test cocks, and full-port shutoff ball valves for easier isolation and servicing.

Q: What are its performance limits?
A: The 720A series typically operates up to 150 PSI maximum pressure and around 33°F–110°F temperature range, with corrosion-resistant bronze construction for durability and freeze resistance.

Q: Is the Zurn Wilkins 114-720A ?
A: Yes. It is ASSE-listed, IAPMO/CSA certified, and approved by cross-connection control standards (including USC Foundation approval) for backflow prevention use. 

• Perform annual inspection and testing by a certified technician to ensure proper backflow protection.
• Check for leaks, cracked body, or worn seals, especially after freeze exposure or pressure surges.
• Ensure the air inlet and poppet assembly move freely and are free from debris or mineral buildup.
• Flush the system periodically to prevent sediment accumulation that can affect sealing performance.
• Protect from freezing temperatures using insulation or seasonal drainage when installed outdoors.
• Replace worn internal components using genuine Zurn Wilkins repair kits only.
• After any service, verify proper operation and retest before returning the unit to service.
