Our verdict

A complete on demand softener with stated flow, resin volume and warranty. The listing also carries stray spec fields that do not apply, so rely on the description.

Overview

Metering water use instead of following a timer, this Fleck 5600SXT softener regenerates on demand, and the complete system ships with the digital control head, resin tank, brine tank and an overflow assembly.

Reason to buy is completeness and clear numbers: control, resin, tanks, bypass and overflow are named, with flow rates and warranty. The limitation is a messy spec sheet and brine tank sizing that the listing words ambiguously.

Who it's for

Homeowners who like set and forget operation, with settings retained through outages, get a digital metered system. Those who want no electrical connection should look at a mechanical model.

Pros and cons

Pros
  • Metered on demand regeneration
  • Settings retained through outages
  • Complete system with tanks
  • Stated flow rates
Cons
  • Needs a power supply
  • Stray spec fields in listing
  • Brine tank size wording unclear

Performance notes

The meter tracks gallons used and starts regeneration only when the resin is spent, which cuts salt use. A capacitor holds the clock through an outage, and non volatile memory preserves programming. Service flow is stated at a pressure drop, which governs how many fixtures can run at once.
