Product Description
The 1000214 is a fixed-orifice backwash flow controller sized for 13in diameter resin vessels, rated at 4.1gpm (15.5lpm), and fits into the drain line flow control (DLFC) housing on Autotrol control valves without needing a separate ball. It regulates how fast water leaves the vessel during backwash so the resin bed lifts and cleans correctly without being washed down the drain. Anyone rebuilding a 13in softener or filter vessel, or seeing resin loss during backwash, needs the correctly sized controller from WrekinWater.

Symptoms that mean you need this part
- Resin or media escaping into the drain during backwash
- Backwash looks weak and the resin bed isn't fully lifting or expanding
- Softener performance declining despite correct salt dosing, suggesting the bed is compacting rather than being cleaned
- The flow controller washer is missing, cracked or warped inside the DLFC housing
Why it fails / why it matters
The drain line flow controller fixes the backwash flow rate to a value matched to the vessel diameter, resin type and typical supply pressure, so the bed expands enough to release trapped sediment and iron without resin being carried out to drain. Fit a controller rated for the wrong vessel size, or run with a worn or missing washer, and you either under-clean the bed or wash resin away, both of which show up as declining softening or filtration performance over time.
Why buy this from WrekinWater

How to fit it
- Isolate the softener at the bypass and shut off the mains supply
- Locate the drain line flow control (DLFC) housing on the control valve body
- Release the retaining cap or clip and remove the old flow controller washer
- Fit the new 1000214 controller into the housing, checking the o-ring is seated and undamaged
- Reassemble the DLFC cap and restore the water supply
- Run a manual regeneration and observe the backwash flow at the drain to confirm the correct rate
