It features a high capacity 48,000 grain softening system with upgraded 10% resin media, making it suitable for households of 2-5 people with a maximum flow rate of 12 gallons per minute. The upflow carbon filtration system is eco-friendly and does not require backwashing, which means it saves on water and electricity, making it a more sustainable option.

The carbon media, derived from coconut shells, effectively removes chlorine, chloramines, pesticides, herbicides, and other chemicals, enhancing the taste and safety of the water. The Fleck 5600SXT digital meter valve, which controls the system, comes with a 5-year warranty, offering peace of mind regarding durability and reliability. The entire system is NSF certified, ensuring compliance with health and safety standards.

Additionally, the product includes a comprehensive installation package with a manual, technical support, and necessary accessories to facilitate installation. On the downside, the system requires professional plumbing installation, which might add extra cost and effort. The unit is also relatively heavy, weighing 100 pounds, which could pose challenges during setup. Although it might be more expensive than other similar systems on the market, its robust performance, comprehensive filtration, and long-term warranties make it a worthwhile investment for households seeking an efficient and reliable water softening solution.

The Fleck 5600 SXT water softener is a strong option for households or light commercial use needing a high capacity system. It has an 80,000-grain capacity which means it can soften a large amount of water before needing regeneration. The system uses a meter-demand regeneration type, so it only regenerates when necessary, helping to save salt and water, which improves salt efficiency. Its control valve is the well-regarded Fleck 5600 SXT model, known for reliability and easy programming. The unit comes with an upgraded large brine tank designed to hold more salt and prevent overflow, which is handy for less frequent maintenance.

Installation is DIY-friendly with detailed video instructions provided, and the system is built in the USA, which can be reassuring for build quality. The system is relatively heavy at 95 pounds and quite tall, so space and handling should be considered. The 1-inch bypass fitting indicates it should handle typical home water flow well but may be less suitable for very large commercial demands.

This water softener is well suited for homeowners or small commercial settings seeking an efficient, durable system that balances water and salt savings with strong softening capacity.

The AFW Premium Fleck Whole House 64k Water Softener System is a robust water softening solution with a 64,000 grain capacity, suitable for large households. One of its main strengths is the upgraded 10% crosslink resin, which is more durable and efficient compared to standard 8% resin, making it resistive to chlorine and other chemicals for a longer lifespan.

The system’s Fleck 5600 SXT On Demand Control Head is another strong point, offering a digital, metered control that allows for precise programming and efficient regeneration cycles, saving water and salt. It includes a complete package ready for installation, which is a significant advantage for DIY enthusiasts, supported by clear instructions and technical support to help you through the process. The 1-inch bypass valve adds convenience, allowing maintenance without disrupting the home’s water supply.

However, at 119 pounds, the system is relatively heavy and might be challenging to handle during installation. Moreover, while the detailed setup instructions and online support are helpful, some users might still find the installation process complex and may require professional assistance. Additionally, the system's large dimensions (12 x 12 x 48 inches) may require ample space for installation. Despite these drawbacks, this water softener is a comprehensive and efficient choice, particularly for those looking for a durable, high-capacity system that maximizes salt and water efficiency.
