Fleck 5800 SXT Digital Metered Whole House Water Softener
The Fleck 5800 SXT Digital Metered Whole House Water Softener
Next-generation Fleck valve with DC motor drive and meter-initiated regeneration — only runs when you need it, saving salt and water every cycle.
Upgrade over the 5600 SXT: The 5800 SXT features a DC motor for faster and stronger gear changes, an improved circuit board for more efficient salt and water usage, and the same intuitive programming interface. If you've run a 5600, you'll feel right at home.
Built to Perform, Designed to Last
Clear LCD Display
Easy-to-read backlit screen with no-hassle programming. Set your hardness level, capacity, and regeneration time in minutes.
Meter-Initiated Regen
Regenerates only after a set volume of water is used — not on a timer — so you're never wasting salt or water unnecessarily.
DC Motor Drive
Stronger and faster than previous generations. The 5800 SXT's DC motor ensures reliable gear changes cycle after cycle.
Day Override Option
The day override prevents you from ever running out of soft water — ideal for higher-usage households.
Downflow Brine Draw
12V downflow brine system delivers thorough resin bed regeneration for consistent softening performance over time.
Fittings & Manual Included
Comes complete with brine line installation fittings and a full owner's manual. Ready to install from the box.

System Requirements
The Fleck 5800 SXT is compatible with standard mineral tank configurations for whole house water softening. Works with all major resin media types including standard strong acid cation (SAC) resin, fine mesh resin for iron reduction, and specialty media. The 3/4" inlet/outlet with included 1" NPT Noryl bypass fits most residential and light commercial plumbing configurations. Available in multiple grain capacities to match your household size and water hardness level — consult your water test results before selecting tank size.
Salt Savings
Meter-initiated regeneration means the system only runs when needed — not on a fixed schedule — reducing salt and water consumption.
Easy Programming
The backlit LCD and intuitive interface make setup straightforward. Most installations are programmed in under 10 minutes.
Whole House Coverage
Six grain capacity options ensure you can match the right system size to your household water usage and hardness level.
Proven Reliability
The Fleck 5800 SXT builds on decades of Fleck valve engineering with upgraded DC motor technology for long-term performance.
