Fleck Water Softener is NOT Worth It! Here’s Why…

Why You Should NOT Invest In Fleck Water Softeners (2023 Update)

Although this article was originally comparing the best fleck softener out of the top 3 models, I have added this update because I am no longer recommending Fleck and here are my reasons:

Red Cross

Basic stand-alone Fleck softeners do NOT filter your water. This means that even though they only cost upwards of $1100, you will still need to pay for a plumber and for a filter otherwise your water is undrinkable. The final costs will be something closer to $1600 – $2000. The final solution will be complicated with different machines doing different things.

Meanwhile there are better all-in-one softener + filter combinations from brands like Aquasana that will treat everything that affects your water NOT just hard water.

Red CrossFleck softeners don’t usually come with filters. However, the few Fleck units with integrated filters typically come with extremely basic filters.

They are likely to only filter sediments and some common contaminants. Whereas the filters that come with other salt based softener systems like the SpringWell whole house softener and filter treat everything. This includes chlorine, viruses, mercury, bacteria and even pharmaceuticals.

Red CrossInstalling a Fleck by yourself can potentially void any warranty that you have. However, other whole house water systems like Aquasana provide you with a professional grade installation kit. This means you can potentially save yourself a small fortune and install it yourself.

The Fleck Corporation

If you are currently in the process of researching water softeners then one brand you will see a lot of is Fleck.

lazy placeholderThis is because it is one of the most well established water softener brands on the market today.

It has raving customers and many of their softeners come with a 5 year warranty.

But the most important question is Fleck any good?

I will answer this question by quickly going through all of their top models. The result of this will be a relatively short post that goes through all the different Fleck models and the different configurations available.

It is only after all this that we can really see the true worth of Fleck.

By the end of this article, you will know if Fleck is right for you and if yes, which model you need to buy.

Why Is Filtering Tap Water So Important?

Effects of Hard WaterYou should not underestimate how much you use water from the tap and how much it actually affects your life, health and well-being.

Think about all the things you rely on tap water for.

Cleaning, cooking, washing your hands, washing dishes, drinking, filling up the kettle or coffee maker, washing expensive home appliances, mixing tap water with food and drink etc.

How do you feel about using hard or contaminated water to do these things?

If you’re reading this article then chances are that you’re the type of person that cares deeply about what you put in your body and the quality of your surroundings.

Still not convinced? Here are some concrete reasons why filtering your tap water is very important:
  • Hard water leaves white residue on your kettle, pots, around your sink and in your expensive kitchen appliances. This not only ruins the appearance of these items but sometimes stops them from working properly.Is Hard Water Bad For You
  • Overtime, your pipes can become clogged and shower heads suffer from residue build up if you don’t filter out water hardness.
  • Water companies and government agencies can sometimes add things to the drinking water supply of a population. Things like fluoride or chlorine. You may want to give yourself the option of not consuming this.
  • No more ugly limescale and residue buildup ruining the look of your kitchen. (Continue Reading: Is Tap Water Safe To Drink?)

The Best Fleck Water Softeners

Here are the top 3 Fleck water softeners that are available on the market. The best one for you will depend on your household’s configuration.

How hard is your water?

Once you have a basic answer to these questions then selecting the right water softener will be a piece of cake.

The process is very simple:

  • Order the test.
  • The testing equipment will then be shipped out to you with a self addressed envelope.
  • Collect your water sample and send it back.

The 3 Top Fleck Water Softeners

1. Fleck 5600 SXT.
2. Fleck 9100 SXT.
3. Fleck 7000 SXT.
Double Line

Fleck 5600 SXT 48,000

This is by far one of the most popular water softeners on the market. Period. Not just a best seller for Fleck but a best selling water softener across all brands.

lazy placeholderAnd it’s not hard to see why.

The Fleck 5600SXT has 48,000 grains and can treat flow rates of up to 12 gpm.

All this geek speak essentially means that it is good for homes with a medium to high hardness level. And it can provide soft water for a 3-6 person home.

This pretty much covers 70-90% of all family homes.

Apart from being suitable for most family homes, it has some cool features:

  • It comes with an easy-to-use electronic controller on a back-lit LCD display.
  • It is easy for you to program the water softener with its touch pad controls.

In terms of softening, the 5600 uses the standard ion exchange process. This means that hard ions like magnesium and calcium are removed from the water.

This regeneration process (i.e. when it produces soft water) is based on a meter. Thereby allowing the machine to only regenerate when it needs to according to your actual water usage.

This machine’s brine tank is a small square box that holds up to 250 pounds of pelleted salt. If you are environmentally conscious then you might prefer to opt for potassium chloride pellets, read my review of water softener salts).

Check Prices & Read Customer ReviewsThis unit has a cool safety feature in the form of a float and overflow drain, which prevents overfilling.

One of the best things about the Fleck 5600 is its two separate warranties:

  • 5 year warranty on the head and,
  • 10 year warranty for the tank.

Fleck 7000 SXT

The higher the Fleck model number the higher the capacity. And indeed the 7000 SXT is designed for a bigger capacity than the 5600SXT. Because it can handle up to 64,000 grains.

Fleck 5600SXTAnd there’s more.

This unit uses one of Fleck’s newer 7000 valve. A 1.25 valve that can handle high pressure flow and can deal with 35 gpm.

The Fleck 7000 water softener’s control is based on an integral microprocessor.

This means that you can program it for very high efficiency. Check Prices & Read Customer Reviews

And by high efficiency I mean it produces soft water with minimum salt consumption.

Fleck 9100SXT Dual Tank Water Softener

This is a water softener machine for heavy duty hardness and high capacity households.It is able to do this because it uses a twin tank system. This means that the Fleck 9100SXT alternates between both tanks.

Fleck 9100SXTThe result? You NEVER run out of soft water.

As I have already mention, if you have a high level of hardness in your home, this is your best bet.

It is able to deal with problem water hardness because of its configuration. The machine’s resin for BOTH tanks have a 1.5 cubic feet capacity.

The fact that the Fleck 9100SXT is capable of producing soft water 24-7 doesn’t mean that it is wasteful.

Check Prices & Read Customer ReviewsThe machine has an On-Demand Flow meter. This is responsible for measuring your water usage so the machine only produces soft water only when necessary.
