Clack Drain Line Flow Control (DLFC), 1.7 GPM (V3162-017)

Description

The Clack V3162-017 Drain Line Flow Control (DLFC) is a replacement flow-control washer designed for compatible Clack control valves. It regulates the flow of water discharged to the drain during the backwash, regeneration, and rinse cycles, helping ensure the filtration media receives the correct cleaning flow rate.

With a controlled flow rate of 1.7 GPM, this DLFC is ideal for appropriately sized water softeners and filtration systems where a lower backwash flow is required.

Why Is the DLFC Important?

The DLFC controls how quickly water exits the valve during backwash. The correct flow rate is important because:

• Too little flow may not properly clean the media bed.
• Too much flow can cause excessive media expansion and potentially carry media out of the tank.
• The correct flow helps provide consistent regeneration and filtration performance.

Important: The correct DLFC size should be selected based on the tank diameter, media type, water temperature, and manufacturer's recommended backwash rate. Do not select a DLFC based only on the control-valve size.

Installation

1. Place the water treatment system into bypass.
2. Relieve pressure from the valve.
3. Remove the drain line elbow or DLFC retainer.
4. Remove the existing flow-control washer.
5. Install the V3162-017 1.7 GPM DLFC.
6. Reinstall the retainer and drain connection.
7. Restore water pressure.
8. Run a manual backwash or regeneration cycle and check for proper operation.

Maintenance

Inspect the DLFC during routine servicing. Sediment, iron, or other debris can restrict the opening and reduce drain flow. Clean or replace the DLFC if the backwash flow is lower than expected.

Why Choose the Clack V3162-017?

The Clack V3162-017 1.7 GPM DLFC provides precise drain-flow control for compatible Clack water treatment systems. Replacing a worn or incorrect flow-control washer helps maintain the proper backwash rate and ensures the filtration media is cleaned effectively.
