Description

The FEBCO Series LF860U-QT is a 1 inch Lead Free Reduced Pressure Zone Backflow Preventer Assembly, engineered to protect potable water systems from high-hazard cross-connection contamination. This robust unit prevents backpressure and backsiphonage of toxic fluids, making it essential for industrial plants, hospitals, and irrigation systems. It features a durable Lead Free cast copper silicon alloy body, union ball valves with quarter-turn shutoff, and a flood detection sensor for enhanced monitoring. Approved by ASSE 1013 and CSA B64.4, this assembly ensures reliable performance and compliance with national plumbing codes.

Help Me Connect

The 1 inch FEBCO Series LF860U-QT backflow preventer features union end connections with NPT ANSI/ASME B1.20.1 threads, making it compatible with standard plumbing connections of the same size. The integrated quarter turn ball valves allow for easy isolation during installation or maintenance.

For proper installation, ensure a 12 inch minimum clearance to any fixed structure around the assembly. The gap drain is designed to handle normal discharge or nuisance spitting from the relief valve; however, the floor drain size may need to be carefully designed to prevent water damage from a catastrophic failure. Do not reduce the size of the drain line from the air gap fitting.

You are required to thoroughly read all installation instructions and product safety information before beginning the installation of this product. Inquire with governing authorities for local installation requirements.

Additional Details

The FEBCO Series LF860U-QT is a 1 inch Lead Free Reduced Pressure Zone Backflow Preventer Assembly designed for critical health-hazard applications. It prevents the reverse flow of high hazard (toxic) fluids into potable water supplies due to backsiphonage or backpressure conditions.

This assembly is ideal for use in industrial plants, hospitals, morgues, mortuaries, chemical plants, irrigation systems, boiler feed, and water lines, or any installation requiring maximum protection against cross-connection contamination.

Features and Components

  • Features a Lead Free* cast copper silicon alloy body for compliance with lead content requirements.
  • Includes threaded quarter turn ball valves with union connections for easy installation and maintenance.
  • Equipped with spring-loaded check valves and a pressure differential relief valve for reliable operation.
  • Incorporates a top mounted flood detection sensor on the relief valve to detect excessive water discharges.
  • The flood sensor, when activated with an add-on connection kit, can trigger notifications to facility personnel, compatible with BMS and cellular communication.
  • Designed as an inline serviceable assembly, requiring no special tools for maintenance.
  • Provides potable water protection against contamination of high hazard (toxic) fluids in water services.

NOTICE: An add-on connection kit is required to activate the flood sensor. Without the connection kit, the sensor is a passive component that has no communication with any other device. Use of the flood sensor does not replace the need to comply with all required instructions, codes, and regulations related to installation, operation, and maintenance of this product, including the need to provide proper drainage in the event of a discharge. Watts® is not responsible for the failure of alerts due to connectivity or power issues.

FAQs

What is the primary function of the FEBCO LF860U-QT backflow preventer?

This assembly is designed to prevent the reverse flow of high hazard (toxic) fluids into potable drinking water systems. It protects against contamination caused by backsiphonage and backpressure.

What does 'Lead Free' mean for this product?

The 'Lead Free' designation indicates that the wetted surface of this backflow preventer, which contacts consumable water, contains less than 0.25% lead by weight. This complies with installation requirements for reduced lead content.

Are shutoff valves included with this LF860U-QT assembly?

Yes, this model includes two threaded quarter turn ball valves with union connections. These allow for easy isolation of the assembly for testing or maintenance.

How does the flood detection sensor work?

The flood sensor is installed on the relief valve to detect excessive water discharges. When an add-on connection kit is used, it can activate flood alerts, sending signals to facility personnel or building management systems for corrective action.

What are the maximum operating pressure and temperature for this backflow preventer?

This 1 inch backflow preventer is rated for a maximum working pressure of 175 psi (12.1 bar). It can operate within a temperature range of 32°F to 140°F (0°C to 60°C).
