Simple, reliable and easy-to-use, the Fleck 5800SXT Electronic Meter-Demand Valve is newer system used throughout the world today.

Advanced technology for advanced performance! The Fleck 5800SXT gives the user the benefit of unique programming and diagnostic features. One key NEW feature is the on-board super capacitor, which keeps the correct time during a power outage up to 48 hours! The programming is stored in memory and will not be lost due to power outages. You may also program the system’s regeneration sequence individually to maximize the efficiency and keep water use to a minimum. Another characteristic is the system keeps time electronically, so the drive motor only runs during regeneration, saving the possibility of motor burn-outs and running more reliably.

The 5800SXT Electronic Meter-Demand system can cut salt and water use by as much as 40%! Unlike timer-based systems, the meter-demand system regenerates only when necessary. The end result? Significant savings in both water and salt.**

** Compared to a system with a timer-based regeneration.
