Product Description
The Fleck 2750 DLFC (Drain Line Flow Controller), covering parts 24212 and 24202, is the small but essential component that regulates the rate at which water flows to drain during your Fleck 2750 valve's backwash cycle. WrekinWater supplies this genuine part for softener and filter owners whose backwash cycle is running too fast, too slow, or not clearing sediment properly, which is a common cause of resin loss or poor regeneration even when the rest of the valve is functioning normally.
Technical specifications
| Part Number | 24212 / 24202 |
| Compatible Valve | Fleck 2750 |
| Component Type | Drain Line Flow Controller (DLFC) |
| Brand | Pentair Fleck |
| Material | Moulded plastic disc with calibrated orifice |
| Function | Regulates backwash drain flow rate |
Symptoms that mean you need this part
- Resin or media appears in the drain line or overflows into the drain during backwash
- The backwash cycle sounds noticeably weaker or stronger than it used to
- Media bed looks compacted or channelled after regeneration, reducing softening performance
- The old DLFC disc shows a worn, enlarged or cracked orifice when removed
Why it fails / why it matters
The DLFC is a precisely sized orifice disc that controls exactly how much water is allowed to flow to drain during backwash, matching the flow rate to the specific media and tank size fitted to your system. Continuous water flow, mineral deposits and general age can wear or clog the calibrated opening, and mishandling during a previous service can crack or dislodge the disc. Once the orifice size changes, the backwash flow rate is no longer correct for your media bed, which can either fail to lift and clean the media properly or wash it away entirely, leading to poor water quality and gradual resin loss.

How to fit it
- Isolate the water supply and switch the valve to bypass if fitted.
- Locate the DLFC housing, typically on the drain line fitting at the back or base of the valve.
- Unscrew or unclip the drain line fitting to access the flow controller disc.
- Remove the old DLFC disc and check the number stamped on it against your new part.
- Fit the new DLFC disc into the housing, ensuring it sits flat and the seal is intact.
- Reassemble the drain line fitting, restore the water supply, and run a manual backwash to confirm normal flow.
