Score: 88/100Rankings

The Fleck 9100 SXT is a dual-tank, meter-initiated water softener designed to provide continuous soft water 24/7 by alternating between two resin tanks. It regenerates automatically based on actual water usage rather than a preset timer, utilizing 8% cross-linked resin for high efficiency. The system is engineered for homes and small commercial applications requiring reliable, uninterrupted soft water delivery.

The AFWFilters Iron Pro 2 is a combination water softener and iron filter designed for whole-house treatment of hard water and ferrous iron. It utilizes fine mesh resin and a Fleck 5600SXT digital metered control valve to remove hardness minerals, iron, and manganese while regenerating on-demand based on actual water usage. It is best suited for homes with 2-5 people dealing with both hard water and ferrous iron contamination.

Professional analysis highlights the system's efficiency in combining softening and iron removal with metered regeneration to reduce resource consumption. The fine mesh resin is noted for its durability in iron-rich conditions, though experts caution that it is strictly for ferrous iron and requires separate solutions for ferric iron issues.
Data indicates that users value the all-in-one nature of the system and the convenience of DIY installation. However, there is limited consumer feedback available, making it difficult to assess long-term user satisfaction or recurring maintenance complaints beyond the standard salt refill requirements.




Professional sources emphasize the Fleck 9100 SXT's efficiency and reliability as its primary selling points. It is repeatedly described as the ultimate in twin tank soft water systems, noted for its ability to deliver continuous soft water while minimizing salt and water usage.
The search results do not include detailed consumer reviews or user feedback from platforms like Amazon, Google Reviews, or other retail sites. However, the product marketing emphasizes user satisfaction through its simple programmability, automatic tank switching, and the peace of mind of never running out of soft water.
