We were able to find a few places online where the Fleck 5600 SXT could be purchased, including Amazon, the manufacturer and other resellers. The company doesn't indicate if the warranty is voided if sold by third-party vendors, so we are left to assume that it is not.

Whirlpool Pro Series Filter + 31000-Grain Water Softener


  • The Whirlpool Pro Series is a water softener and whole-home water filter in one unit.
  • Smart sense learning technology (6th Sense patented) learns your home's water usage and predicts when more salt is going to be added.
  • Predictive modeling also allows it to know when to start recycling water.
  • Water filter never needs to be replaced.


  • It is recommended to use a water softener cleaner, which can get pricy.
  • Whirlpool advertises free installation with the purchase of the system, but it turns out to cost money.
Krystal Pure KS 64000-Grain Water Softener


  • The Krystal Pure KS is an upgraded model to the company's previous offering. It features an extended tank to process more water at a higher rate of speed.
  • Smart meter tech allows the system to conserve sodium by learning the household's habits.
  • The system is virtually maintenance free.


  • Like some technology, the smart usage meter doesn't always run efficiently and isn't always accurate.
  • The manufacturer does not get great marks for customer satisfaction with resolving issues.

The Benefits and Drawbacks

The Fleck 5600 SXT has some features that put it above the rest and some that aren't as great. Let's take a closer look at the good and the bad.

First off, the LCD screen is the best in the industry by far. It beats out the three models compared above hands down. The screen allows the user to easily and quickly assess the water quality running through the system at any given time. You don't have to wait for the system to test it; it's always monitoring the level and displaying it, which makes it unique in comparison to other models. It also monitors the salt level and the amount of fresh water available at the time of reading. It can give you an accurate reading of how much you have left before the system needs to start cycling again. Only the Whirlpool model above gave a comparable reading of the salt levels.

You can also program the system to automatically clean the water in certain intervals of time. For instance, if you decide to cycle the water and regenerate it on Wednesdays and Sunday mornings because your house is empty during those times and no one will be affected by the regeneration, then you can set it to complete the cleaning at those points during the week. This doesn't mean that it won't regenerate as demand calls for it to. It just means it will take the time to recycle and clean also during the times you tell it to. This feature is an improvement on the other models, as they don't necessarily allow you to choose a regeneration cycle.

Now to discuss some of the negative points about the 5600 SXT, the main negative is that the system has to be hooked up through the plumbing in your home. There are water softening systems, like the Pelican system reviewed above, that do not require installation by a plumber but gain access through a pipe that you can install yourself. The 5600 SXT does involve some measure of know-how to hook into your plumbing system.


  • Bright LCD meter makes it easy to know how much soft water is remaining
  • The regeneration rate can be scheduled, or you can let it run manually
  • The system is quick to process water and uses less salt to do so
  • Excellent warranty, although not as thorough as the Pelican model


  • Needs to be installed by a plumber, unlike other systems
  • The system can be pricy compared to other options, although the Pelican system is pricier


If your home is suffering as a result of hard water, it's time to consider investing in a Fleck water softener. One of the models offered, and the model reviewed in this article, is the 5600 SXT. After reviewing the product thoroughly and comparing it to like products, we conclude that the system is more than adequate in cleaning mineral deposits out of a household water supply. With all the features, ease of use and warranty, we conclude that the Fleck 5600 SXT is a great option to consider when shopping for a water softening system for your home.

Final rating: 4.5/5
