Fleck (61451-25) 1/2" BLFC 0.25 GPM

The Fleck 61451-25 drain line flow control is a precision-engineered component that restricts backwash and regeneration drain flow to exactly 0.25 gallons per minute through a 1/2" connection. This BLFC (Brine Line Flow Control) ensures your Fleck control valve maintains proper cycle timing and prevents drain line overwhelm during softener regeneration.
SPECIFICATIONS

Technical Details

Manufacturer Fleck
Model Number 61451-25
Connection Size 1/2 inch
Flow Rate 0.25 GPM
Component Type BLFC Drain Line Flow Control
Application Water softener control valves
Material Durable polymer construction
Thread Type Standard 1/2" MPT
INSTALLATION & USE

Installation Steps

  1. Shut off water supply to the softener and relieve system pressure before removing the existing drain line flow control or plug from the control valve drain port.
  2. Thread the Fleck 61451-25 into the 1/2" drain port opening, hand-tightening first, then snug with a wrench without over-torquing the plastic threads.
  3. Attach the drain line tubing to the outlet side of the flow control, ensuring a secure connection that won't work loose during high-flow regeneration cycles.
  4. Restore water supply and initiate a manual regeneration cycle to verify proper drain flow rate and confirm no leaks at the connection points.
COMPATIBILITY

System Requirements

The Fleck 61451-25 flow control is designed for use with Fleck control valves including the 5600, 5600SXT, 7000, 9000, and 9100 series. This component is essential for systems where drain line capacity is limited or where precise control of regeneration discharge is required to prevent backflow or drain overflow. Compatible with both upflow and downflow softener configurations using standard 1/2" drain line connections.

🔧 Pro tip: If your softener cycles are completing too quickly or you're experiencing drain line backup, verify you have the correct GPM-rated flow control installed. The 0.25 GPM model is ideal for smaller residential systems with limited drain capacity, while larger systems may require higher flow models to prevent extended regeneration times.
