Autotrol Brine Refill Controller 1.3 gpm. p/n 1000519 for 255, 263, 268, 278, Magnum - Logix Valves (No Ball included)

The 1000519 is the 1.3 US gpm brine refill flow control washer used in the refill flow control assembly on Autotrol 255, 263, 268, 278 and Magnum-Logix control valves. It meters the rate at which water refills the brine tank at the end of regeneration, and the higher 1.3 gpm rating suits the larger brine tanks and higher-capacity resin volumes typical of this valve family compared with the smaller ECO-series valves. This is the master flow washer only, without the check ball, for reuse of your existing ball or systems that don't fit one. It's stocked by WrekinWater as a precision replacement part.

Technical specifications

Symptoms that mean you need this part

• The brine tank is filling with noticeably more or less water than usual at the end of regeneration
• Softening performance has dropped and the brine solution looks weaker or stronger than normal
• The refill flow washer is visibly cracked, chewed, or has lost its calibrated orifice shape
• You're servicing the refill flow control housing and find scale or debris built up around the washer

Why it fails / why it matters

Brine refill flow controls are precision-calibrated orifices that set the exact volume of water refilling the brine tank, which in turn determines the strength of the brine solution for the next regeneration. On 255, 263, 268, 278 and Magnum-Logix valves that 1.3 gpm rating matches the larger brine draw these valves are typically sized for. Scale and grit gradually erode or partially block the orifice even when the washer still looks sound, and the result is an incorrect refill volume that shows up as weak brine, salt bridging, or a brine tank filling to the wrong level. Fitting a fresh, correctly rated washer restores the intended flow rate.

How to fit it

1. Isolate the softener at the bypass valve before opening the refill flow control housing
2. Locate the refill flow control assembly, typically housed in the brine well fitting or valve head depending on your softener
3. Unscrew the retaining cap and withdraw the old flow washer, keeping your existing check ball to refit if your system uses one
4. Fit the new 1.3 gpm 1000519 washer into the housing in the same orientation as the original
5. Reassemble the retaining cap, tightening by hand only to avoid cracking the housing
6. Run a manual brine refill cycle and check the brine tank fills to the correct level with no drips at the fitting
