COMPATIBILITY & APPLICATIONS
Works With Fleck 5600 Series Control Valves
This flow control washer is designed exclusively for Fleck 5600 and 5600SXT mechanical and electronic control valves. It installs in the brine line to meter the exact amount of saturated brine drawn from the tank during regeneration. The 0.25 GPM flow rate is calibrated for standard residential water softener applications. Over time, these washers can wear or become obstructed by sediment, leading to incomplete regeneration or salt bridging. Replacing the 12094 washer restores proper brine flow and ensures your softener delivers consistently soft water. This is a genuine Fleck OEM part, not an aftermarket substitute.
💧 If your softener isn't using salt as expected or you're experiencing hardness breakthrough, check the brine line flow control washer first — it's a small part that has outsized impact on regeneration performance.
