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.

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 Fleck 5600 SXT water softener is a solid choice for households needing reliable water softening with its 40,000-grain capacity, which means it can handle moderate to heavy water hardness before needing regeneration. This capacity is supported by 1.25 cubic feet of upgraded 10% commercial-grade cation resin, which is effective at removing hardness minerals. It uses a digital metered demand control valve, so it regenerates only when necessary based on your water usage, helping improve salt efficiency and reducing waste.

The system includes a durable black mineral tank preloaded with resin and a brine tank with a safety float, which simplifies setup and maintenance. The 1-inch Noryl plastic bypass valve allows easy installation and maintenance without shutting off the entire water supply. Additionally, the manufacturer offers DIY video instructions, making it user-friendly for those comfortable with home projects. Weighing 53 pounds and measuring 10 x 10 x 44 inches, it’s a fairly compact unit suitable for many home utility spaces.

It offers a substantial 48,000-grain capacity, which is beneficial for households needing significant water softening. The metered softener regenerates based on water usage, improving salt efficiency and saving on operational costs.

The backwashing carbon filter effectively reduces particulates, tastes, odors, and chemicals, which enhances the water quality for drinking and household use. This dual-functionality makes it a valuable asset for homes relying on city water or well water that is free from iron, hydrogen sulfide, and bacteria.

The digital control valve, Fleck 5600SXT, is user-friendly and known for its reliability and ease of operation. However, at 180 pounds, the unit is quite heavy and may be challenging to install without professional assistance.

For those needing a comprehensive solution to both soften and filter water, and who don't mind the bulk, this product is a strong contender.
