In this review, we will cover the Fleck 7000 SXT digital metered water softener with a 48000 Grains. It is similar to 5600 SXT model but is more appropriate for larger homes and internal ports with higher water flow rates. Fleck is a trusted producer of water softeners and has been voted to be the best choice for softening hard water.



  • Detailed instructions included to simplify the installation, so you might not need a plumber
  • Meter-based regeneration saves water and decreases salt use
  • 10-year warranty on the valve, and 5 years on the tank
  • 48-hour power back up capacitor to prevent your tank from missing a regeneration cycle in the event of a power outage
  • Two day power backup; backwashes twice during regeneration
  • 48,000 grain capacity address the water hardness in large homes efficiently


  • Very heavy, weighing a solid 132 pounds, so you might need some help when carrying it to its location in your home
  • Might be too big for smaller homes with average water usage
  • Salt-based water regeneration could taste a little odd at first, and could also increase your sodium intake
  • You might need to purchase some additional converters, so you should get advice from a plumber if you are not sure of the installation

How we conducted the test:

We got a team of evaluators and tried this product and observed it to see its performance given specific purposes. We also logged in the number of hours that we spent in testing the models.




Is It Worth Your Money?

This is reasonably priced, and the value meets the price. You'll get an extremely effective product for the whole house, and judging by the user reports, it will also last you for a very long time.

The expected lifespan of this unit is from 20 to 30 years! That's 2 to 3 times the industry average.

Furthermore, if you have some basic plumbing skills, you might not even need to call a plumber. The exhaustive installation manual is easy to use, and you should be able to set up your softener in less than 2 hours. You'll only need to do a few simple plumbing connections and go through several detailed steps to program the metering valve.

Bear in mind that you should know your water's hardness and iron levels before you program the SXT control head. If you are not sure of your water conditions, take a sample to your local hardware store or send it to Fleck for testing.

Detailed Breakdown

Here's everything you need to know about the Fleck 7000 SXT 48,000 Grain model.


  • Weight: 132 pounds
  • Good for up to 4 bathrooms
  • Salt capacity: 250 pounds
  • Easy to install
  • Flow Rate: 15 GPM
  • Can last up to 30 years
  • Grain Size: 48000


The 7000 SXT is the newest addition to the popular 7000 series, and it has advanced programming and diagnostic features. The modern controller features a touch screen LCD, a two-day power backup, and an easy to use interface.

It has an on-demand water regeneration option, like the previous models from Fleck. The SXT control valve will trigger the regeneration only when the tank reaches its full filter capacity. This way, you can expect to save 40% more salt than with a standard timed regeneration system.

Furthermore, the 7000 SXT model stands out as it backwashes twice during regeneration. As no salt can clear out every particle in the tank, the minerals build up with time in other systems as they rinse only once per regeneration. Although there is still a small amount of grain in the tank, your meter would still show the maximum capacity.

But with the double rinse feature of the Fleck 7000 SXT, the meter will stay accurate for a much longer period, and you won't have to worry that your water will get harder any time soon.   

With this model, you can also manually adjust the regeneration cycles to minimize water and salt usage. The time is monitored automatically, so the drive motor will only work during regeneration. This adds to the reliability and prevents motor burn-outs.

The high flow rate control valve has an exceptional performance and efficiency rating. It's perfect for meeting the needs of an upscale home. It is designed for both 1 inch and 1.25-inch pipes and has the highest backwash flow rate. The flow that you'll see in your home is 15 gallons per minute.

Maintain your softener by always keeping it plugged in. Also, make sure that the brine tank is at least at water level at all times.

This system will also save you money on the electricity bill. Even if you needed a regeneration cycle once per day, it would add only five dollars to your electricity bill for the entire year!


  • Weight: 132 pounds
  • Width of the square salt tank: 14 inches
  • Height of the square salt tank: 34 inches
  • Width of the mineral tank: 10 inches
  • Height of the mineral tank: 54 inches
  • Color: Blue or black
  • Flow rate: 15 GPM
  • Salt capacity: 250 pounds


You can purchase the Fleck 7000 SXT Water Softener and expect to pay for the shipment because of the weight of the item. Furthermore, some additional fittings might be necessary for the installation.


With 48,000 grains per gallon, this softener will easily deal with water with a high concentration of hardness minerals. It is efficient for large homes, with up to four bathrooms. The high effectiveness and quality of this product also make it a good choice for small businesses. 

If you were to use it for smaller homes, you would see even more savings in salt and water usage during regeneration.

Our Opinion

The Fleck 7000 SXT 48,000 Grain Water Softener is a good deal with an upgraded control head over the 5600 SXT models. It only costs more for the upgraded head. That being said, the 5600 SXT controls are adequate for most users, so the 7000 head is only necessary for those who want the touchscreen and double backwash rinse.

Other Options Worth Looking At

The Fleck 5600 SXT 48,000 Grain Water Softener is our site-wide favorite. It costs a little less and performs just as well as the 7000 SXT model.

If you need something with a higher grain capacity, you can look into the Fleck 9100 SXT Twin Tank 80,000 Grain Water Softener. With two tanks, you’ll never need to wait for it to regenerate to supply soft water.

Another option is the Fleck 64000 Grain. For those who are looking for competitors, you can also see our Fleck vs GE article. You will also get a plethora of choices from our main page.
