Description
The Zurn 1-375 Reduced Pressure Principle Assembly provides high hazard protection against backsiphonage and backpressure in non-potable water applications. Designed specifically for high-performance needs, this 1 inch backflow preventer is a top choice for irrigation contractors seeking reliability and low lifecycle costs. It is built to function effectively even in the most corrosive water environments, offering the same robust performance found in the 975XL model. Efficiency is at the core of this assembly. The innovative EZSwap Pressure Vessel is removable, allowing for easy access and added convenience during maintenance. This design, combined with the included Flush Tool (FLUSH), simplifies line flushing and quick winterization. By streamlining these processes, you can save up to 15 minutes per installation or repair. With a high pressure rating of 175 psi and a durable construction that resists corrosion and mineral build-up, the Zurn 1-375 ensures long-term protection and ease of use in demanding plumbing and irrigation systems.
