Investing in the right water softener for your home has multiple effects on your general quality of life.

Even moderate water hardness levels can take their toll on your appliances and clothing over time.

  • Fleck 9100 SXT Twin Meter On Demand Water Softener: For City Water
  • Fleck 5600 Econominder Mechanically Metered Water Softener: Value for Money

Top Choices on the Market

Best Fleck Water Softener Reviews 

1. Fleck 9100 SXT Twin Meter On Demand Water Softener: Best Water Softener for City Water

 9100 SXT Twin Meter On Demand



  • Strong and sturdy engineering
  • High-quality resin for filtering
  • Straightforward method for choosing appropriate capacity
  • Designed to save up to 15% in salt
  • Very heavy, making single-person installation difficult

The Fleck 9100 SXT works hard to filter out hard water so your other appliances don’t have to. The meter display is easy to understand, and troubleshooting is minimal thanks to the reliable technology. 

The twin tank system works by switching from the first tank to the second when the first one is empty. The computerized meter on top makes it easy for users to set up the switching system during installation.

Once it’s been set up, users generally will not need to make any future adjustments unless their water usage needs change dramatically. The memory chip even keeps your settings saved in case of a power outage or other interruption.

The grain capacity of a given water softener makes a huge difference in the effect the softener has on your home’s water. With 7 different grain capacities to choose from, this model allows any family to get the perfect softener for their single-family home. However, Fleck 9100 water softener reviews indicate that the 32,000-grain model is the recommended minimum, even for small homes in moderate water hardness areas.

Having a higher grain capacity range makes this model the best option for homes with large bathtubs and other water appliances. Larger grain capacities for this unit also provide sufficient gallons per minute for 2 family members to shower at once without your system having to switch over to hard water.

2. Fleck 5600 Econominder Mechanically Metered Water Softener: Best Fleck Water Softener for the Money

5600 Econominder Mechanically Metered



  • Up to 20 GPM depending on grain capacity
  • 4 regeneration settings
  • Around half the cost of larger models
  • Cheaper materials aren’t as durable
  • Single tank drains faster than twin tanks

The double-backwash valve system on the 5600 SXT has a piston-seal-spacer assembly that’s precision-engineered for hassle-free daily use. Since the water system only has one moving internal part, there’s less risk of breakage and other maintenance issues.

The computerized mechanical meter options include immediate meter regeneration, delayed time clock regeneration, delayed meter regeneration, or day of week regeneration. This makes the system even more efficient for small families who don’t use a lot of water. It also includes a capacitor to keep your settings from being lost during power outages of up to 48 hours.

The screen on the meter shows the number of gallons remaining at any given time. This is especially helpful for families trying to plan their water usage.

Although Fleck has other single-tank options, Fleck 7000 SXT water softener reviews often mention maintenance issues, so the 5600sxt is generally regarded as a better option. The slightly newer Fleck 5800 has a better valve system, but Fleck 5800 water softener reviews indicate that it may not be worth the price, especially if reliability and cost are your priorities.

Despite its lower price point, this Fleck water softener still carries a 5-year valve warranty and 10-year tank warranty. This dedication to service frequently comes up in Fleck 5600 SXT 48,000 grain water softener reviews.

3. Fleck 9000 SXT Twin Digitally Metered Water Softener: Best High GPM Residential Water Softener

9000 SXT Twin Digitally Metered



  • Digital meter works without interruption 
  • 7-grain capacity options
  • Only 2 moving parts inside water stream
  • Injectors don’t get clogged easily
  • Harder to install than the newer 9100 model

As one of Fleck’s slightly older models, the 9000 SXT does not have quite the same technology level as the 9100 or other new models. However, the 9000sxt is still a workhorse that delivers powerful water pressure of up to 27 GPM. Although exact GPM varies depending on the grain capacity, the output for this model generally exceeds similar residential models.

This increase in GPM makes a vast difference for larger homes where multiple people might shower at once or for families with large bathtubs or hot tubs. Although it won’t entirely compensate for low water pressure from wells or municipal systems, it still may improve pressure consistency, especially since it has 2 tanks to draw from.

These tanks are also powerful enough to provide water for small-capacity commercial locations such as coffee shops and laboratories that need soft water. The variety of tank sizes available make it a good option for specialized settings that need enough water to function, but don’t have any extra space to spare.

The 9000sxt meter system uses just 24 volts to keep your energy costs as low as possible. The meter also helps save on salt since the regeneration settings are optimized to only regenerate when necessary. Overall, it’s a smartly-engineered water softener that can cut down on hassle while delivering the water pressure you need.

4. Fleck 9500 SXT Commercial Water Softener - Twin Tank: Best Commercial Water Softener

9500 SXT Commercial



  • Massive capacity options
  • Peak flow rate of up to 66 GPM
  • Brine tank with grid plate for better saturation
  • More expensive than basic residential models
  • Takes up large horizontal and vertical area

If you have a very large home and live in an area with hard water, you may need a commercial water softener to keep up with all your water needs. Small- to medium-sized businesses like coffee shops and restaurants also need a more robust water softener than what standard models can offer.

The 9500 SXT from Fleck is a leading commercial water softener model. Although it’s not large enough for hotels or other businesses with dozens of showers, it’s more than enough for most restaurants, office buildings, and other establishments with many sinks and toilets.

Since water softeners decrease the amount of iron that reaches your other appliances, they may even reduce general equipment and maintenance issues over time. Appliances typically have to work harder when using hard water, and softening that water may help.

The total space required varies somewhat, but since tank size range from 16” x 65” up to 24” x 72”, the total required space is up to 73" x 39" x 88". This makes the tank less viable for residential spaces, but it’s a worthwhile investment if you need a larger capacity.

Fleck’s commercial water softeners are backed with a 5-year warranty for both the tank and valves. The meter for the 9500 SXT is user-friendly and has clear features so users can make adjustments without calling in a maintenance technician.

5. Fleck 2510 SXT Water Softener System for Well Water: Best Water Softener for Well Water

2510 SXT



  • Available with additional filtration options
  • Base model is very affordable
  • Uses 10% cross-linked resin for better results
  • Lifetime warranty on tanks and resin
  • Automatically adjusts to water regeneration needs
  • Single-tank system for lower overall capacity
  • Add-on filtration options are expensive

Every well water system is different, and even neighbors on the same street may have unique well situations. Deeper wells often cannot deliver the same water pressure as shallow wells, and over time, families often end up digging deeper and deeper to maintain access to water. Minerals in the soil have a significant impact on water quality and can even be harmful to your health.

Fleck has risen to this challenge by creating a water softener system that can be highly customized based on your local water’s iron, sulfur, and heavy metal content. The water softener can also be customized to match your well water output level for more consistent water pressure.

Each component in the system is built with strong mesh filters to keep unwanted elements out of the final water supply. Since each optional tank is around the same size, you can easily plan their installation and even add on or replace equipment later.

Due to the multi-tank system, installation and setup naturally take a little more time than other water softeners. However, Fleck 2510 water softener reviews say that this effort is worthwhile due to the system’s stellar results for removing iron and other contaminants. Ongoing adjustments are also easy thanks to the easy-to-read and intuitive screens on each device’s meter.
