FULL IN-DEPTH REVIEW
Read Our Full Fleck 5600 SXT Water Softener Review Below:
A lot of water softeners on the market proclaim to outperform the others. However, when you get down to the nitty-gritty of it, there’s a limited number of systems that genuinely stand out and perform as expected. Fleck 5600 SXT is one of those we wholeheartedly recommend.
It delivers all the benefits you want from a water softener: effective removal of corrosive magnesium and calcium, resulting in treated water that's easier on your appliances, plumbing, fixtures, hands, skin and hair.
Simply put: it does the job! And it does it well.
Before we outline everything we like about this system, here's what several of our customers have said about the Fleck 5600 SXT water softener.
“The soft water is wonderful. We’ve been living with hard water for the last 10 years. When our valves and fixtures began failing, freezing up, and breaking, we decided it was time to get a water softener. We’re very happy with our purchase!”
“My Culligan broke down, and I wasn’t willing to pay the $120 service charge on top of what they were charging me to fix the unit. Having had Culligan for 15 years and paying for service calls as high as $600, I figured I should try the DIY option. I reviewed the Fleck 5600 SXT. I had soft water within minutes of running the backwash and regeneration. I love it!”
“This is the second water softener of this same model that I have purchased. Once for my last house a few years ago, and once for my new house. This thing WORKS.
Fleck is a name you can trust. Don’t waste your time on cheapo models you find at big box stores. These (Fleck 5600 SXT) are engineered to work and to last and do so efficiently. This one is enough to handle my very hard (24GPG) water and my large family’s monthly usage.”
The Fleck 5600 SXT commands respect with its rough and tough design. This water softener is made to last and it's mean enough to take a bite out of hard water!
This system comes preloaded with resin and is easy to set up.
You not only save a lot of dough on this bad boy upfront, but you get all the bells and whistles that top-of-the-line water softeners come equipped with, for a very competitive price.
Let’s unpack this feller and see what he’s all about!
The Fleck 5600 SXT is a bestselling system that comes backed with hundreds of thousands of positive reviews and ratings across the internet. Across the board, product reviews on this system are enough to sway those shopping for a water softener to purchase this system. Customers are very happy in choosing this system. In fact, people consistently report that it performs above and beyond their expectations.
This system is manufactured by Pentair, which is a highly reputable leader in the water treatment solutions. Pentair is transparent with its commitment to maintaining the highest business, ethical, moral, and civic standards in every aspect of their business.
Guess what? This water softener is USA-made!
This water softener comes preloaded with excellent-quality 10% crosslink resin. Traditionally, most water softeners use an 8% resin, which has a much shorter lifespan. Resin is one of the main components you need to pay attention to when purchasing a water softener.
Those little balls are not just “balls.” Resin is like the beef to your burger. Without a good quality resin, you are left with a bun for a burger!
So, why the hype on resin? Well, resin is clear little beads that are present in your tank. These little guys are the key players in the ionization process, which removes minerals in your water. Those minerals are why you have hard water. If you have heavily chlorinated water, 10% resin is ideal because they hold up to the deterioration that chlorine causes with a lower percent resin.
The last thing you want is your resin “checking out on you,” requiring you to replace it.
A prime example is using an 8% resin where the water contains a high concentration of iron and/or chlorine. That resin may not last the anticipated 20 years. When this happens, you are faced with the timely chore of getting your water softener back up and running.
For even greater efficiency, consider upgrading your Fleck 5600 SXT to High Efficiency SST-60 Resin.
In addition to the longer lifespan, this resin can significantly save on salt and water usage. In fact, we've found that High Efficiency SST-60 Resin can save up to 40% on salt and 60% on waste water.
That can translate into significant money savings in the long term.
Plumbers, Handymen, and Weekend Warriors
Easy for DIYers, plumbers, handymen and friends! Installing the Fleck 5600 SXT is fairly easy.
If you have basic plumbing skills, you are all set! We want to make it as easy as possible, so we throw in a few extras to help you with the installation. You’ll get bonus quick connectors free with your purchase of this system (be sure to select this option at checkout).
Customer’s comments about installation speak loudly for this system!
Let's face it. We expect our home systems, like a water softener, to function flawlessly. And Fleck is known for lasting for the long haul.
However, in the event that something unexpected happens, the Fleck 5600SXT water softener has your back with a 10-year warranty on the tank and a 5-year warranty on the valve.
That's decent coverage to give you peace of mind (even with a system made to last much longer).
UPGRADE OPTIONS REVIEW
Whole House & Under Sink Water Filters
When you purchase your Fleck 5600 SXT unit, you’ll get the choice of adding on three different filters.
These filters removes different water content and they each can compliment each other. This means that you can go with one, two, or all three, depending on your budget and how pure that you want your water to be.
We have long-time customers that have had their KDF filters for 15 years and still going strong.
The KDF55 will remove 99% of heavy metals, chlorine, and won’t let bacteria grow inside of your system, so you’ll get good healthy water throughout the house.
The really unique benefit about the SoftPro R/O filtration is the addition of the alkalizing filter. Standard RO filter systems will lower your water’s pH to 6 or 6.0, making it acidic.
You may be aware that our bodies don’t do well on acidic water as there have been lots of studies done on Reverse Osmosis (RO) Drinking Water Filters on this subject. This is why it’s important to alkalize your RO water so you’re getting pure, clean, delicious, AND totally healthy water...
It comes with a long reach chrome handle… but if that’s not going to match your current faucet, you can give us a call and we’ll swap out the chrome for a different color if we have it available, absolutely free. When you choose a SoftPro R/O filter system you’ll enjoy deliciously alkalized, fully filtered bottled-quality water at your kitchen sink.
It comes with a long-reach chrome handle… but if that’s doesn't match your current faucet, you can give us a call and we’ll swap out the chrome for a different color if we have it available, absolutely free.
When you choose our RO system you’ll enjoy deliciously alkalized, fully filtered bottled-quality water at your kitchen sink.
SoftPro reverse osmosis system can handle 75 gallons per day of drinking water, which is more than plenty. It’s a high-efficiency system also. Most RO filters waste 3-5 gallons of water for every 1 gallon of filtered water. But our RO system is a 1:1 ratio, making it much very efficient.
For that whole house bottled water, we recommend the Whole House Catalytic Carbon Filter. Use catalytic carbon instead of coal or coconut because it removes chlorine AND chloramine at high flow rates. This very hard to remove and the traditional filters just can’t handle it.
Catalytic carbon is more expensive, but it will do the job and give you the highest quality, best tasting, healthiest water, throughout your home.
This carbon filter removes it all: pesticides, herbicides, pharmaceutical products, petroleum products, and heavy metals.
The filter lasts about 7-10 years and replacing it is easy. You’ll only replace the carbon, not the entire system.
It requires no regular maintenance, no regeneration, no water waste, and no electricity.
HOW EACH FILTER PROTECTS YOU

It regenerates only when needed. Isn't that how all water softeners should work these days?
The Fleck 5600 SXT digital metered valve is a step up from the 5600 Econominder mechanical meter. It intelligently monitors your water flow, regenerating only when there's a need. So, on days when your water usage is lower, the system won't bother regenerating.
That efficiency ultimately saves you money on salt, water and electricity.
The Fleck 5600 SXT comes with a robust paddle wheel design that keeps it moving smoothly like a hot knife through butter. You won’t have to worry about it sludging down and sticking on you like other brands of meters out there.
It’s a big plus to have this feature and ultimately means LESS MAINTENANCE.
The headache of having to remove and clean out the traditional turbine-styled meters are gone when you use a paddle wheel meter.
The Fleck 5600 SXT comes with a large, easy-to-read backlit LCD screen. It comes pre-programmed folks! You don’t have to fiddle with settings and programming it. But if you like having more control, there's plenty of programming options you'll love.
The blue backlighting makes it easy to read. Heck, you can even tinker with this thing in the dark!
Some of the fantastic features include a service/diagnostic indicator that lets you know when you need to give it some TLC. The time you see on it indicates your time zone, not some other time zone across the country.
If you lose power, this little guy has a 48-hour internal backup to keep things going.
Are you pumped and ready to get your Fleck 5600 SXT water softener? Folks, we can’t say enough about this system. Its simplicity and performance will have you hugging it as soon as your soft water begins to flow!
