Detailed Description of the Features

Ease of use

The device comes with a detailed instruction manual which makes the installation simple and easy. Some of the customer reviews suggest you ask help from a plumber to install the system. The company responded to this by uploading a series of videos on their site to make it even easier which can be found here. Bear in mind that you should have an idea on the hardness level of your water before you program control head. Take a sample of water to the local hardware or send it to Fleck to test the ratings. 

Along with that, Fleck SXT is easy to maintain. If the hardness level changes or you need to increase the regeneration cycle, a few touches in the settings section of LCD is all you need! 

Value for Money

If you’re shopping for a moderately priced water softener with high-end features, Fleck 7000 SXT will not disappoint you. Apart from saving your expenses in installation, the product offers exceptional durability. The average life expectancy of SXT is 20-30 years, which is 2 to 3 times the industry average. Verifying that claim with real user’s experience, we assure that Fleck’s product will last for a very long time. 

Additionally,  the SXT control valve will trigger the regeneration only when the tank reaches its full filter capacity which saves 40% more salt than with a standard timed regeneration system.

Fact: A regeneration cycle once per day with Fleck 7000 SXTwould add only five dollars to your electricity bill for the entire year!

This confirms that this product is reasonably priced, and the value meets the price.

Major Applications

Fleck 7,000 SXT Water Softener supplies 48,000 Grains per gallon. The water softener will easily deal with all kinds of water, regardless of hardness. This makes this product highly effective and versatile, making it a good choice for any kind of residence or small business.

With large grain capacity, Fleck is efficient for large houses with up to 4 bathrooms. Also, if you have a smaller house, the product will save you, even more, salt and electricity due to less regeneration. 

It is designed for both 1 inch and 1.25-inch pipes and has the highest backwash flow rate. This makes it perfect for meeting the needs of an upscale home!

  • 48-hour power back up in the event of a power outage

Our Verdict

We doubted the system’s installation based on some customer reviews. However, upon close inspection, it was found that the issue was easily removable with the use of additional converters which can be purchased from the local hardware. The SXT valve comes completely assembled so you won’t be tinkering around when you could be using the soft water instead. With projected lifespan longer than any other products in the market, warranties during purchase, and realistic savings in energy consumption, Fleck SXT definitely takes the cake as one of the best water softeners for your home or office.

The Fleck 7000 SXT 48,000 Grain Water Softener is a good deal with an upgraded control head for those who want the touchscreen and double backwash rinse.




The hardness setting is the entering water hardness to calculate how much water can be treated before regeneration. It allows you to increase or decrease the hardness level by programming it on the display. The hardness output cannot be adjusted. 

The processed water is 100% soft.

The only other part needed to install the system is the plumbing fittings as those vary in each application.

Although the manufacturers recommend this product for a house with 4 bathrooms, the supply depends on what flow rate you have available and also what your hardness is. This system will treat up to 12 GPM.

Please refer to the manufacturer’s site for detailed information on your specific needs.

The working mechanism of Fleck 7000 is similar to that of 5600 SXT. Contrary to the 5600 SXT model, 7000 SXT is more ideal for larger applications requiring higher flow rates like large homes and businesses. 

Fleck 7000 SXT works on 110V.  All connections and the resin tank are waterproof so you should be able to install it outdoors. However, we would recommend you to cover the electronic control unit for obvious reasons.
