10 Best Fleck 5600 Sxt Water Softeners 2025 in the United States

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.
