DuraWater Fleck 5600SXT

Expert Review Analysis

The DuraWater USA Fleck 5600 SXT is a 48,000-grain whole-house water softener featuring a digital metered valve for on-demand regeneration based on actual water usage. It utilizes high-capacity fine mesh resin in a fiberglass tank to remove calcium and magnesium, offering significant salt and water efficiency compared to traditional timer-based systems.

✓ Best for: Medium households (4-8 people) with moderate-to-high water hardness (10-20 gpg) and daily usage between 200-400 gallons. Ideal for homes with three or more bathrooms where simultaneous shower usage is common, and for extending the life of plumbing and water heaters in areas with well water or municipal supplies causing scale damage. Suitable for areas with iron content below 3 ppm.✗ Not ideal for: Very large households with more than 10 people who require higher capacity models (64K+ grains). Homes with low-flow needs where a smaller 32K model would be more appropriate. Users who cannot maintain minimum 20 psi inlet pressure or those who prefer timer-based systems without metering capabilities.

Pros

✓Metered regeneration adapts to household usage, saving up to 50% salt and water compared to timed systems
✓Fleck 5600 SXT valve includes NOVRAM memory and internal capacitor to retain settings during power outages

Expert Opinion

Professional reviewers and editors consistently praise the DuraWater USA Fleck 5600 SXT as a highly efficient and reliable whole-house solution. Experts highlight the metered regeneration capability as a key advantage for adapting to variable household water needs, noting it saves significant resources compared to timer-based systems. The proven engineering of the Fleck 5600 valve is commended for its durability and low failure rate, while the pre-assembled design is noted for facilitating easy, quick installation. Editors also appreciate the user-friendly interface and the system's ability to maintain settings during power outages, making it a top choice for medium-sized homes seeking balance between efficiency and performance.

What Users Say

Everyday consumers generally express high satisfaction with the DuraWater system, particularly appreciating the 'set-it-and-forget-it' nature of the metered regeneration. Users frequently report significant savings on salt usage and immediate improvements in water softness, noting the elimination of soap scum. The quiet operation and reliability during power outages are also common points of praise, with many users reporting years of trouble-free service. However, recurring complaints focus on maintenance issues such as salt bridging in the brine tank, occasional meter glitches, and the high water consumption during regeneration cycles. Some users also note that achieving full flow rates requires adequate inlet pressure.

Common Complaints

Salt bridging in the brine tank requiring manual intervention; occasional meter glitches needing system resets; high water consumption during regeneration cycles; installation adjustments needed for bypass fit; requirement for minimum 20 psi inlet pressure for optimal flow.
