Having looked at many genuine Fleck water softener reviews online, I will quickly discuss the pros and cons of all the top models. I will look at their different configurations and features.

However, I’ll start by explaining their benefits because you’re probably more concerned with why this brand is worth the cost, right?

Top Fleck Water Softeners

Finding the best water softener for you and your home depends on a number of different things. The first and perhaps most important is to determine how hard your water is.Crystal Quest Standard Softener

Water hardness is when your water contains a high amount of hard dissolved minerals like calcium and magnesium.

Once you work out your water hardness, then you’ll get a better idea of which type of water softener model is best for you.

ALL the fleck models below treat a high level of water hardness. The key difference being their ability to deal with things like low pressures systems, high capacity etc.

1. 5600SXT = 1-4 person household + medium hard water
2. 7000SXT = 4-6 person household + medium to very hard water.
3. 9100SXT = 5+ person household + very hard water.

Fleck 5600SXT Water Softener

Good for: High hardness level and 3-6 family home capacity.

This is by far one of Flecks most popular water softener systems. The 5600 SXT comes with a 48,000 grain capacity that can treat flow rates with up to 12 gpm.

Crystal Quest Whole House Softener Filter ComboThis option is good for…

…homes that have a medium to high hardness level. The capacity is good for homes that house three-six people.

When buying the Fleck 5600 water softener you will also get an electronic controller. The best part is that the controller has a backlit LCD display. Its very own touch pad control allows you to easily program the water softening unit.

When it comes to actual softening, the Fleck 5600 uses the ion exchange process. In English, this means that anything considered to be hard ions like calcium and magnesium ions are removed from the water.

Because you can but the regeneration process on a meter, the Fleck 5600 SXT only creates soft water when it needs to.

The brine tank design means it can hold up to 250 pounds of pelleted salt. (Pelleted salt is a better choice if you’re thinking about costs. While potassium chloride pellets are for you if you prefer the eco-friendly option.)

This unit also comes with a safety float and overflow drain, which prevents overfilling.

Fleck 5600 SXT has not 1 but 2 separate warranties. It comes with a 5 year warranty on the head and a 10 year warranty for the tank. It has many positive customer reviews, which you can check on Amazon.

Fleck 7000SXT Water Softener

This Fleck model is ideal for people who need a bigger capacity water softener. This is because it can handle 64,000 grains (which is a lot!).Aquasana Superior Filtration Detail

This specific model uses the Fleck’s 7000 valve, which is one of the latest valve types.

It is a 1.25 valve that allows a high pressure flow and works with 35 gpm.

The Fleck 7000 SXT water softener has got an integral microprocessor which controls the device.

However, you can program it to make sure it is highly efficient at creating new soft water but uses minimal salt consumption.

Fleck 9100SXT Dual Tank Water Softener

The 9100SXT is a twin tank system. This means it is much more efficient and has a faster processing time.

Aquasana Whole House InfographicThe tanks alternate which means you never run out of soft water.

If you have a high level of hardness and need a larger capacity, this machine is right for you.

It is particularly good for a large family household or commercial setting. This is because the Fleck 9100SXT has something called an “On-Demand Flow meter”.

The meter looks at how much water you use and then only produces more soft water when necessary.

Here is some technical information for those that need it. The maximum flow rate for this unit is 12 gpm. While the resin for each tank has a 1.5 cubic feet capacity.

Fleck Water Softener Installation

One of the best things about fleck is that you don’t need a professional plumber to install it for you. This is unlike many other water softeners that are more expensive.

YouTube is full of tuns of videos that take you through the installation process step-by-step. Below is one example of an official video by ABCwaters (the makers of Fleck) showing you how to install a Fleck water softener.

Fleck Water Softener Price

Fleck whole house waster softening systems tend to cost upwards of $600, with units that provide a higher capacity of water softening being more expensive.

Is Fleck Softener WORTH It?

The short answer is no.

Mr Water Geek ThinkingIf you go through the many customer fleck water softener reviews online a common remark is how easy it is to use the units.

Others comment on how efficient Flecks machines are and most people seem to be very happy with the water softening results.

If you’re on a tight budget Fleck has more affordable offerings that still deliver good water softening capabilities.Crystal Quest Standard Softener

However, I no longer think buying a Fleck is a good idea.

The main reason is that fact that Fleck softeners don’t provide you with adequate or integrated water filters.

Flecks ONLY treat hard water. That’s it.

This means that when I recommended people to get a Fleck in the past they usually come back asking for how to get their water filtered and I didn’t have any quick or easy solutions.

But there are more reasons why I don’t recommend Fleck anymore.

Let me explain further.

Why You Should *NOT* Buy Fleck.

Although this article is supposed to be about “Fleck Water Softener Reviews”, I am no longer recommending Fleck for the following reasons:

Red Cross

Fleck softeners do NOT filter your water. This means that even though they only cost upwards of $600, 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 $1500 – $2000. The final solution will be complicated with different machines doing different things.

Red CrossMeanwhile 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 Cross Fleck 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. Meanwhile the filters that come with Aquasana whole house systems treat everything. This includes chlorine, viruses, mercury, bacteria, pharmaceuticals and even lead.

Red Cross Installing 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.

Fleck vs Aquasana? (Whole House Salt FREE Softener + Filter)

  1. I’m struggling with what system to put it, need a full home water filtration system to clean and soften the water. And perhaps purified system under the sink. Culligan came out and did their thing, I’ve been researching online and reading a lot about Fleck and APEC, and I have someone coming out from a local company tomorrow TB water. After testing our water is measuring 230 for hardness and on the high side for chlorine for 4m something.. help.

  2. Looks good, I’ll probably need the 9100. What about a filter for the entire home to remove chlorine and ammonia? Could you offer a recommendation? In my continued research sounds like the coconut based filter is the best way to go? No? Thanks!!

  3. From what I know about coconut based filters, they are more eco-friendly but not as effective as traditional water filters. If you’re worried about chlorine and ammonia then you’ll need something that removes “chloramines”. You should consider getting Aquasana’s Whole House Water Systems… I reviewed whole house systems and Aquasana was my favourite when comparing all top models… https://www.mrwatergeek.com/best-whole-house-water-filtration-system/

  4. I have a fleck, the smaller black one. I live in NW Fl. I have sediment build up on my faucets and am wondering if the Softner
    Is defective. I do have soft water but everything in my house has water spots in clouding drinking glasses washed in the dishwasher . Any ideas how to fix this problem?

    • Hi Marie

      A sediment build up on the faucet and cloudy spots on drinking glasses suggests the water softener is not working well. You can try regenerating so that it reboots. If the problem persists, get a plumber in to check it out or get it fixed for free if it’s still under warranty.

      If you’re in the position to get a new softener then Crystal Quest provide a salt-based softener + whole house filter that also comes with a 6-month guarantee and lifetime warranty.

      Stay hydrated,
      Luke

  5. I’m thinking about getting the Fleck 9100 STX. I live in San Diego and have 5 members in my home average 70-80 gallon per person. Would you recommend the 9100 or a different model and what grain size should I consider? Thanks.

    • Hi Pat

      Yes, the Fleck 9100STX twin tank model will be able to provide enough soft water for a home of 5 people.

      It’s a good solution if you ONLY need soft water.

      This machine will not deal with any other issues or contaminants in your water unlike Aquasana.

      Hope this helps.

  6. We purchased an EcoWater ECR3700R70 in January for around $8k. It has not worked since day 1. They even swapped it out with a new one last month and same results. At best, we have soft water 1-2 days per week. I’m seeking a refund. Our raw well water is 80-100+ gpg in hardness!! We use an average of 150 gallons/day, as metered by the unit. Which Flex 9100sxt model would be the best option for us? Can it stand up to our extremely, ridiculously hard water?

    • So sorry to hear you had problems with your EcoWater system.

      Yes, the Fleck 9100SXT dual tank will be able to treat that level of extremely hard water. However, it will not filter anything out. This means you will be left with soft but undrinkable water that’s still full of contaminants.

      Something like the Crystal Quest softener and filter is able to treat up to your level of gpg (which I calculate to be 5.835 gpm). It has a multi-stage filter that filters out contaminants like pesticides and industrial solvents.

      Stay hydrated,
      Luke

  7. I have a Fleck 9100 dual tank system. Can I backwash both tanks at the same time. I have been doing 1 at a time which is take 3 hours to do.

    • Hi Rachel
      I’m really not sure and would not want to give you the wrong information.
      You should really speak to the manufacturer to make sure you don’t completely damage your 9100.
      If it’s made by Pentair then contact them through: tech-support@pentair.com
      Please let me know how it gets resolved as I’d like to update my own knowledge on this issue.
      Best wishes,
      Luke

  8. This really is a bogus review. Fleck system does a great Job of removing harden mineral. I for once, only want a water softener in my home since I have a water filtration system under the kitchen sink and my Refrigerator has an integrated filter. And since I do not drink water from the shower, or hose, a total water filtration system is not needed. You review is unbiased, if we are talking about water softening system, then Fleck is a great value and WQA certified. I coils buy any of those system that you mentions without a total home water filtration system. Your review doesn’t make any sense.

    • Hi Javier

      I don’t understand why you are so upset?

      Most of the article talks about how good Fleck is. There is a whole section that talks about “The Benefits of Using Fleck” and I talk about everything you mentioned.

      However, you need to remeber that a) many people want a single device that softens AND filters because this is easier for them b) a salt free softener is more convenient and less hassle c) Fleck do not provide a lifetime warranty unlike other brands.

      If you love your Fleck, good.

      I actually think they are good basic standalone softeners and I say this over and over in my article.

      But I’m also allowed to present alternative solutions that other people might find better.

      Stay hydrated,
      Luke

  9. Thank you for all of the information in this review. We are new to water softeners in our house. What do you think about the Watershield brand/label?
