Description

The Febco 905-532 Series 601-M air gap drain fitting provides a crucial connection for 1/2 to 1 inch Febco 860/LF860 and 860U/LF860U reduced pressure backflow preventers. Constructed with a durable ASTM A48 funnel and ASTM B26 Alloy 356 connector, this metal drain fitting is coated with black Vitralon polyurethane for corrosion resistance. It effectively funnels moderate relief valve discharge from pressure fluctuations or minor check valve fouling, reducing splashing. The unit features a 1 inch Female NPT connection for direct piping to a drain, ensuring proper water management in non-health hazard applications.

Backflow Assembly Connection

  • The air gap drain attaches directly to the relief valve port of 1/2 inch to 1 inch Febco Series 860/LF860 and 860U/LF860U reduced pressure backflow assemblies. Use the provided self-tapping screws to join the funnel halves over the tabs on the relief valve port.

Drain Pipe Connection

  • The bottom of the air gap drain features a 1 inch Female NPT connection for piping discharge to a suitable drain. Ensure the drain line diameter is not reduced from the air gap fitting.

Additional Details

The Febco Series 601-M Air Gap Drain is designed for installation on 1/2 to 1 inch reduced pressure assemblies to manage moderate relief valve discharge.

This metal drain fitting reduces water splashing and funnels discharge from backflow prevention devices into a drain, specifically for Series 860/LF860 and 860U/LF860U models experiencing pressure fluctuations or minor check valve fouling.

Features

  • Reduces water splashing around the reduced pressure assembly.
  • Funnels moderate relief valve discharge directly into a drain.
  • Constructed of corrosion-resistant material with stainless steel mounting fasteners.
  • Designed for non-health hazard applications.

A CAUTION: This drain is intended to catch moderate relief valve discharges. Under certain conditions, relief valves can discharge water at rates greater than the drain capacity. Consult local codes for installation requirements.
