Real-World Performance
In daily use, the AFWFilters Fleck 9100SXT excels at providing soft water nonstop. Because of its dual alternating tanks, one tank regenerates while the other is in service, so you don’t experience downtime. This seamless operation is a game changer—you won’t have soggy laundry or grainy soap residue in your sinks. One user shared an experience: "Since installing this system, my pipes feel cleaner and plumbing issues caused by scale have dropped dramatically." It consistently handles hard water without noticeable drops in flow rate. The system’s efficient use of salt and water during regeneration also means fewer refills and less maintenance overall.
Reliable Soft Water Flow Consistently
What Makes It Stand Out?
Compared to other water softener systems, the Fleck 9100SXT dual tank design stands apart by guaranteeing a continuous supply of softened water—no interruptions during regeneration. Many single-tank softeners can leave you with hard water during this process, but this system’s alternating tanks prevent that. Another popular competitor, the Whirlpool WHES40E, offers a single tank and simpler digital controls but doesn’t deliver the same uninterrupted soft water experience.
The digital control valve on the Fleck 9100SXT also outperforms manual valves and basic timers found on some models. It adjusts regeneration based on actual water usage, promoting efficiency. Against another competitor like the Eddy Electronic Water Descaler, which uses no salt or resin but only conditions water, this AFWFilters system physically removes hardness minerals, providing true soft water benefits.
