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.

Combo Package Fleck 5600SXT 48,000 Grain Water Softener and Backwashing Carbon Filter

The Combo Package Fleck 5600SXT is a robust water softener and backwashing carbon filter system suitable for addressing common water issues. 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.

Buying Guide for the Best Fleck 5600 Sxt Water Softeners

Choosing the right water softener is essential for ensuring that your household water is free from the minerals that cause hardness, such as calcium and magnesium. A good water softener can help prevent scale buildup in your pipes and appliances, improve the efficiency of your water heater, and make your skin and hair feel softer. When selecting a water softener, it's important to consider several key specifications to ensure you get the best fit for your needs.
Grain CapacityGrain capacity refers to the amount of hardness the water softener can remove before it needs to regenerate. This is important because it determines how often the system will need to regenerate, which affects both water and salt usage. Grain capacities typically range from 24,000 to 80,000 grains. For a small household with 1-2 people, a lower capacity (24,000-32,000 grains) may be sufficient. For larger households with more water usage, a higher capacity (40,000-80,000 grains) would be more appropriate. Consider your household size and water usage to determine the right grain capacity for you.
Flow RateFlow rate is the amount of water the softener can treat per minute, measured in gallons per minute (GPM). This is important because it affects the water pressure in your home. A low flow rate can result in reduced water pressure, especially during peak usage times. Flow rates typically range from 7 to 20 GPM. For a household with 1-2 bathrooms, a flow rate of 7-10 GPM may be sufficient. For larger homes with more bathrooms, a higher flow rate (12-20 GPM) is recommended to ensure adequate water pressure. Consider the number of bathrooms and water fixtures in your home to choose the right flow rate.
Regeneration TypeRegeneration type refers to how the water softener renews its ability to remove hardness. There are two main types: time-initiated and demand-initiated. Time-initiated systems regenerate at a set time, regardless of water usage, which can lead to inefficiency. Demand-initiated systems regenerate based on actual water usage, making them more efficient and cost-effective. If you have a consistent water usage pattern, a time-initiated system may work for you. However, for most households, a demand-initiated system is preferable as it adapts to varying water usage and reduces waste.
Salt EfficiencySalt efficiency measures how effectively the water softener uses salt to regenerate. This is important because it affects the operating cost and environmental impact of the system. High-efficiency models use less salt and water during regeneration, which can save money and reduce environmental impact. Look for systems with a high salt efficiency rating if you want to minimize salt usage and reduce maintenance costs. Consider your willingness to manage salt levels and the environmental impact when choosing a system with the right salt efficiency.
Control ValveThe control valve is the component that regulates the water softening process, including regeneration. A reliable control valve ensures consistent performance and longevity of the system. Look for control valves that are known for their durability and ease of use. Some advanced control valves offer digital displays and programmable settings, which can provide more control and convenience. If you prefer a set-and-forget system, a basic control valve may suffice. However, if you want more control over the settings and monitoring, consider a system with an advanced control valve.
