Zurn Wilkins 34-720A 3/4 Pressure Vacuum Breaker Assembly

The 720A Pressure Vacuum Breaker Assembly, a 3/4 in. device, is designed to protect against backsiphonage in high health hazard, non-potable residential and commercial irrigation applications. Featuring an approved check valve, vacuum relief, two test cocks, and inlet and outlet full port resilient seated shut-off valves, the 720A offers a maximum pressure of 150 psi and a temperature range of 33°F to 110°F. Constructed with corrosion-resistant internal parts and a durable all-bronze bonnet and body, this assembly provides added strength and protection against light freezes. The strategic placement of the test cocks on the center line of the valve allows for installation versatility.

Designed for installation on potable water lines, the Wilkins Series 720A pressure vacuum breaker assembly is engineered to safeguard against the back-siphonage of contaminated water into the potable water supply, offering protection where a potential health hazard exists. The visible serial number in any installed orientation reduces labor time during installation.

Consistent and reliable performance, along with the assembly's corrosion-resistance, strength, and winterization protection, make it a world-class solution for backsiphonage prevention. The 720A is ASSE Listed, IAPMO Listed, and CSA Certified, and is approved by the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California.

The main valve body is made of cast bronze (ASTM B584), while the fasteners are constructed with stainless steel, 300 Series, ensuring durability and long-lasting performance.
