10 Best Fleck 5600 Sxt Water Softeners 2026 in the United States

The Fleck 5600SXT Water Softener system is a robust option for households looking to manage water hardness. It boasts a 48,000 grain capacity, making it suitable for average-sized homes. This system comes with a digital metered control head, which means it measures water usage and regenerates as needed, saving on salt and water. The 'set and forget' feature is particularly convenient, requiring minimal maintenance other than adding salt periodically.

The included installation kit and pre-loaded resin tank simplify the setup process, even for those not familiar with plumbing tasks. The upgraded 10% crosslink resin is a notable strength, as it better handles chlorine compared to standard 8% resin, potentially extending the system's lifespan in areas with chlorinated water. However, at 120 pounds, it is on the heavier side, which might make installation difficult for some users without help.

The 5-year warranty on the control head adds a layer of reliability. This water softener system, being a complete package, is ideal for homeowners seeking a long-term solution to hard water issues without frequent intervention.

The AFW Filters Built Fleck 5600SXT 48,000 Grain Water Softener with Upflow Carbon Filter is a comprehensive whole-house system designed to soften water and remove contaminants. 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.
