The Ultimate Fleck 5600SXT Review 2019 – Is it the Best Water Softener System?

My Ultimate Fleck 5600SXT Review – Updated on November 17th, 2019: Water is one of the most important things you need for ultimate health and cleanliness. With that being said, you would want to make sure that what you are using is quality water deemed safe and great for cleaning! Hard water is a common issue across the states nowadays. You’ll know if you have hard water when it’s difficult to make suds when washing, or your clothes and dishes soon start to have odd stains and spots! Since you are already on this page, I assume you are already having hard water issues in your home and looking for a solution to get rid of it. That is why it should be in your best interest to invest in a good water softening system, such as the Fleck 5600SXT.

My Home vs. Hard Water

I know how troublesome it can be when you have hard water with high scales in your household! When I moved to Texas last year, I was surprised with how hard the water was! It really sucked, having to endure dishwashing with the soap not being soapy enough to clean my plates, as well as those darn spots that stained my clothes and utensils. My drains were clogged because of the quality of the water, and I suffered from so much more problems just because of the water alone! Having hard water is definitely something you wouldn't want to endure unless you're up for working extra hard just to make suds and wash.

Introducing the Fleck 5600SXT

Sure, it helped a bit, but I still found myself back to the same situation. Until I found out about the Fleck 5600SXT. It took away all my problems on hard water! This is a product I would definitely recommend to anyone facing hard water issues of high and moderate level or scale, especially in regions like Texas, Kansas, Arizona, California, New Mexico, Alaska, and Tennessee. In this article, I'll give you my personal and true review on the Fleck 5600SXT!

Before I Give My Take on the Fleck 5600SXT...

But before going through my own review, let me be honest. Before purchasing the Fleck 5600SXT water softening system, I spent a LOT of time reading various reviews on it! I researched for the specs and features, as well as what to expect from the system. I've searched for loads of customer reviews online, even asking salespeople and other professionals about the brand! This is what encouraged me to purchase the system. Now that I have bought it and found out about its many great uses, I decided to create my own review as well to help YOU out!

About the Manufacturer

Fleck is manufactured by Pentair Ltd. It's a multibillion dollar company that is from Worsley, Greater Manchester UK. It is known as one of the most popular companies in the water softener business. It's also got other brands other than water softeners, making them successful with other appliances and devices related in the water field! WIth growing business comes the same quality and advancing technology, making Pentair's products top-of-the-line and worth every penny clients pay for. They use the most advanced of information and technology to create their products, and the Fleck 5600SXT is no exception! They have a lot of satisfied customers (I included), and they are known for their great customer service and quality products with the best-known warranties.

Shipping and Package

I ordered the system online, and am happy to report that the seller shipped the unit immediately. It took just a matter of days! The brine tank was well packaged and safely secured in the box, as well as the control unit, which was placed inside the brine tank. I checked the Fleck control head, which was made with quality and in metal parts, which is way better as compared to the other water softening systems I had made out of plastic. I also love the fact that it comes with tons of different colors to fit the motif and design of your home. As for me, I chose the color black to make it blend with my home's colors and to have it look less noticeable. It comes in a variety of colors to choose from, including yellow!

The package came with an instruction set, which was very helpful. It's a detailed step-by-step guide that will definitely help you get the system up and running in no time. The manual was very easy to understand, with me only going over it a few times before I got it. You don't even need a plumber or have any skills whatsoever, just the ability to follow the steps. This saves you a ton of money and work. What's great is that if you don't get the instructions, you won't need to cry out in despair. Simply contact or call them for immediate help.


Installation may take about two hours, depending on how skilled you are. As for me, I was working alone and am not very knowledgeable with plumbing and whatnot. With that being said, it may take less time if you have a background in plumbing, and if you had an extra pair of hands as well. You will need to install the house filter and softener, which was fairly easy. I could say that pouring the resin beads into the tank would be the toughest part of the job, which needs the extra pair of hands. Take note that the beads are heavy, which is why you'll need help unless you are strong enough or would like to make a mess, spilling all the beads to the floor! It's best to have someone hold the funnel. If not, you can use duct tape to help you out.

Also, take note that you should switch off your water supply before installing the water softening system. I forgot to do so, and I ended up with hard water for a few days until that supply ran out and the soft water began pouring in. Also, its size will take on small to medium households. If you have a bigger household, then it's best to get a bigger capacity of the unit to ensure the water supply to flow continuously, or depending on how much water your whole household uses.

Another perk when purchasing the Fleck 5600SXT water softening system was that it had a 10-year warranty for the tank and a 5-year warranty on the control head, making it a great deal. You'll be able to easily contact their customer support for help if ever something goes wrong, and they will repair or replace the unit, depending on the conditions applied.


Once the system is now secure and successfully installed, then you will now have to carefully follow the instructions on programming it to soften your water supply. No worries, though, as programming the controller is very easy. All you need to do is to know the water hardness, system capacity, and the water usage. In time, you'll be surprised with the power of the Fleck 5600SXT water softening system and the filter that comes with the unit! But don't be surprised with the amount of rust you'll see, as it is made of metal and it will meet with water. But the filter is made out of quality materials, helping filter out the dirt and rust from the softened water. It has a great layer of protection, so you'll be confident that the water you are consuming and using is quality and safe to use.

Performance and Durability

As for the performance, I can say that everything works perfectly and as expected. I actually feel like it did better than what I wanted! Now, I don't need to worry about hard water anymore. It makes it much easier to create suds when washing dishes or bathing, and all my clothes and dishes look better as well. My drains aren't clogged, my shower tiles aren't stained, and I definitely love the many benefits I got with the soft water I needed. Plus, I can say that consuming water is now safer and tastes better.

I've been using this for over a few months now, and it's more durable than any other water softening system I've ever had. It's easy to clean and maintain and is best for those with medium households like mine (depending on the water use or consumption). No matter how long we've been using it, it still does the job as if we just installed it. Many other users have raved about how it is able to still do the job efficiently for years.


As time passes by, some water softeners have issues with the resin and brine tank. But with the Fleck 5600SXT, that's not the case! I have used it for a few months now, and I have experienced no problem with it. It does a great job with the default settings as suggested in the instruction manual in order to keep your water soft. So long as you follow that and maintain it the right way, then you won't have any problem and only notice the superb quality of soft water you get, way different from the hard water I used to suffer from before water softening systems.

When it comes to cleaning and maintenance, don't expect the system to clean the iron out immediately. It's playing its part as expected and will require time. With that being said, I recommend that you check it out for daily cleaning and maintenance, maybe around once a week or before replacing the resin seeds.

In a Nutshell

All in all, I love the unit and how it does the job with efficiency. Their customer service is great, the package complete with perks, and the overall performance is amazing. I don't have to worry about hard water anymore! I'm actually purchasing another Fleck 5600SXT unit as a present for my daughter's wedding anniversary because of how great it is!
