Fleck 5600 Standard Piston Assemblies – Mechanical Control Valves
These Fleck 5600 standard pistons are genuine replacement parts designed specifically for older-style Fleck 5600 mechanical control heads. Available in multiple colour-coded options, each piston is matched to a specific valve configuration to ensure correct operation, efficient regeneration, and long-term reliability.
⚠️ Important: Fleck pistons are colour-coded for a reason. Always replace your piston with the same colour as the existing piston fitted to your valve. Fitting an incorrect colour piston may result in poor performance or regeneration issues.
Available Fleck 5600 Mechanical Pistons
FL24116 – White Cap Piston
FL18089 – Blue Cap Piston
FL24117 – Grey Cap Piston
👉 Please refer to the second product image and match the colour of your existing piston before ordering.
Compatibility & Important Notes
✔️ Suitable for Fleck 5600 mechanical (non-electronic) control valves
❌ Not suitable for Fleck 5600 SXT or SE electronic valves
Electronic Fleck valves require electronic piston assemblies and seal kits, which are listed separately
Different motor generations were used during production – colour matching is essential for correct function
Key Benefits
Correct regeneration performance when the correct colour piston is selected
Reliable water softener operation using genuine Fleck components
Direct replacement – no modification required
Restores efficiency in older mechanical Fleck 5600 valves
Typical Applications
Domestic water softeners using Fleck 5600 mechanical timers
