Fleck 5600SXT is a top-rated whole house water softener and perhaps one of the most reliable models available on the market that come at a reasonable price. It’s a powerful and comprehensive digital system packed with a lot of incredible features that make it outshine its competitors.
The unit is one of the best models from Fleck which is a brand owned by Pentair Water Treatment Company. However, although it’s manufactured by Fleck, there are several other brands that are selling it under their name.
Fleck also has four other similar models under the 5600SXT series that offer different grain options. They include the 5600SXT 32,000 Grain system, the 5600SXT 64,000 Grain system and the Fleck 5600SXT 80,000 Grain system.
All these models employ almost the same technology and design with the only thing setting them apart is the capacity. It’s a thoughtful consideration that gives you the opportunity to choose the right size for your home but still get the same quality system as the rest. Even much better is the fact that you can also pick the brand you like.
This review is a thorough analysis of the Fleck 5600SXT 48,000 Grain water softener and it will show you exactly what propels it to the top of our list as well as how it compares to the other three models.
The Fleck 5600SXT is a 2-tank salt-based softener that uses the effective ion exchange process to get rid of water hardness.
The mineral tank comes filled with 8% cross-linked resin which is not only quite a powerful resin but it’s actually the industry standard.
In terms of softening performance, this high-capacity resin is very effective and will remove all the undesirable mineral ions like magnesium and calcium ions from the water which are the primary materials responsible for the formation of the damaging limescale deposits. It can efficiently handle very hard water with hardness levels of more than 30 grains per gallon.
Besides the impressive softening capability, this unit employs a smart regeneration process which is one of our favorite features.
It’s a meter based regeneration system featuring an advanced computerized flow meter that initiates regeneration automatically without requiring your presence.
The meter monitors and measures how much water you use in the house, then it self-regenerates the system based on these measured readings.
This clever approach simply means that it will regenerate only when necessary plus the meter is designed to modify its settings should there be any change in the water usage.
If there’s an increase in the water demand, it will adjust accordingly such that it’s able to regenerate more often to match the growing water needs.
In other words, whether it’s a time of low or high water usage, this system will always work at the right level translating to a reduction in the running costs as it saves salt and helps reduce waste.
The unit uses around 40 to 50 gallons of water during regeneration which is pretty decent considering that older water softeners that regenerate on a timer usually waste a lot of water and salt. The regeneration process takes a total of about 1 hour and 50 minutes.
As we mentioned earlier, the Fleck 5600SXT is a 2-tank water softener with a relatively large capacity to ensure you have softened water available 24/7. It’s a 48,000-grain capacity system which is sufficient for medium to large households with moderate to very hard water. It’s a perfect fit for a family of up to 6 people or more.
In addition to the large capacity, this Fleck system is capable of putting out about 12 gallons of water every minute. This is a high flow rate suitable for a whole house system like this and it’s enough to allow you to run multiple water sources without a drop in pressure in any of them.
The brine tank is equally large and can hold around 250 pounds of pelleted salt, so you won’t be replenishing it frequently like other smaller-sized units.
To keep the system operating smoothly, the 5600SXT is equipped with a safety float which helps prevent the overfilling of the brine tank. When the resin tank malfunctions, often the water held in the brine tank tend to rise too high or overflow.
It’s a rare scenario, but should it happen, it makes a mess or can even flood the house. The safety float will turn off the water going into the brine tank as soon as the level gets too high thereby preventing overfilling.
Fleck has also included an overflow drain alongside the safety float which serves as an additional backup to provide protection against overflowing or water spillage.
This unit as well comes with a bypass valve which is a thoughtful little feature that allows you to repair the unit without having to shut off the water for the whole house.
Furthermore, it helps ensure a continuous flow of water into the house throughout even during regeneration although it will be hard.
For larger houses or should you need more capacity, Fleck has two other options that offer higher capacity. The first option is the Fleck 5600SXT 64,000 grain softener which can serve 6 to 8 people while the second one is the Fleck 5600SXT 80,000 grain softener which offers the largest capacity sufficient for a family of at least 10 people.
There’s also a 32,000 grain model for those that need a smaller capacity softener for a family of fewer than 5 people. Other than the difference in capacity, the three models have almost the same features as the Fleck 5600SXT.
The most intriguing feature on this Fleck 5600SXT 48,000 grain softener has to certainly be the SXT controller. It’s the latest controller from the manufacturer, a very nice touch that’s packed with a contingent of useful features you want most in a water softener system.
It includes a backlit LCD display, touchpad controls and best of all, an internal power backup that can last up to 48 hours.
The LCD display has a very user-friendly interface that makes it easier to operate the system. It’s a helpful feature, especially for first-time softener owners. You can check the system’s status, the time left for regeneration or any error codes that might need troubleshooting.
The included touchpad controls allow you to fully program the system to your preference. It has a good range of customizable options for the regeneration process.
You can set the time at which the system will regenerate, and the days you want it to run after every regeneration cycle (default is 14 days). There are 4 modes of regeneration you can choose from as well which include immediate, delayed meter, delayed time and day of the week.
There’s also a double backwash option which is another helpful feature, particularly for those whom their water has high iron content or is extremely hard.
In simple terms, by allowing you to program the system, this Fleck softener gives you a great advantage as you are able to set the best time for it to run.
This way, you get your softened water whenever you need it and during the time that you don’t need it, the system is regenerating which is basically a win-win situation.
The best part about this SXT controller is that although you can configure the time it will regenerate, the computer is intelligent enough to learn for itself. It will learn your household’s water use and determine how often it has to regenerate, then schedule itself accordingly.
Generally, while controllers tend to be an issue when it comes to such type of water softeners, this Fleck’s SXT controller by far provides a more convenient and efficient system of scheduling.
What’s more, is that it’s equipped with an internal power backup which is a safety net in case of a power failure. It can effectively run the system for up to 48 hours.
Installation and Maintenance
Installing the Fleck 5600 SXR softener requires some basic plumbing skills. It’s not super easy nor is it super hard. All you need is a bit of plumbing know-how and you will have not much to worry about.
The kit includes everything needed for installation plus a detailed instruction manual and the resin comes preloaded in the tank. If you get stuck, there are several helpful videos on YouTube you can refer to.

The amazing thing though is that Fleck has designed this unit for easy operation and maintenance thanks to the simple and user-friendly digital controller as well as the meter-based regeneration process.
The only regular maintenance you will need to do is replenishing the salt in the brine tank every once in a while of which the digital display will show you the time remaining before you can do this.
The tanks are made out of a strong poly glass that’s highly durable and they are further backed by a 10-year warranty while the control head is backed by a 5-year warranty, all of which represent remarkable quality and reliability.
