The Watts LF919-Qt-S-FS Backflow Preventer is a high-end solution designed to protect water supply systems from contamination. This device is a must-have for commercial, industrial, and residential applications that require the highest level of water safety and compliance with regulations enforced by local health departments and authorities. In this product description, we will provide a comprehensive overview of the Watts LF919-Qt-S-FS Backflow Preventer, discussing its key features, benefits, and applications.
Design and Construction:The Watts LF919-Qt-S-FS Backflow Preventer is a double check backflow preventer, featuring a dual protection mechanism that ensures uninterrupted water flow while maintaining a foolproof barrier against backflow. It's manufactured from durable, corrosion-resistant materials, such as brass and stainless steel, ensuring longevity and reliability even in the most challenging environments. Moreover, the device is approved by the American Water Works Association (AWWA) and meets or exceeds the requirements of the NSF International, NSF 61/ANSI 61, and NSF 372 standards.
Functionality and Performance:The Watts LF919-Qt-S-FS Backflow Preventer operates based on the principle of maintaining water pressure to prevent backflow. It consists of two independently acting, spring-loaded check valves. When the water pressure is higher in the downstream side, the first check valve is closed, and the second check valve remains open. Conversely, when backpressure occurs upstream, the first check valve opens, and the second check valve closes, preventing contaminated water from entering the clean water supply system.
Installation and Maintenance:Installing the Watts LF919-Qt-S-FS Backflow Preventer requires a certified and experienced plumbing professional to ensure proper connection to the water supply line and the adherence to local regulations and codes. Regular maintenance and testing are crucial for the optimal performance and longevity of the device. The Watts LF919-Qt-S-FS comes with a built-in test port that allows for easy access to perform periodic backflow prevention assembly tests.
