No matter where you live in the USA, the likelihood you have hard water is high – according to the United States Geological Survey, over 80% of households in America have hard water.

Hardness minerals can damage your plumbing, bathroom, and kitchen fixtures, as well as your expensive appliances.

A water softener can help solve the issue, but which one to buy? The Fleck 5600SXT might fit the bill. Read on to find out more about it.

Fleck Water Softener Overview

Fleck is one of the oldest and most trustworthy water softener manufacturers in the USA. The brand is owned by US Water Systems, Inc. and is located in Indianapolis, Indiana.

Perhaps the greatest advantage when buying from them is the prompt and efficient customer support. The company is easy to reach, and the operators speak both English and Spanish, catering to all consumers. Throw in excellent product quality, and you’ve got a winning formula.

Fleck manufactures a range of water softeners and water filter systems, valves, parts, and accessories. Finding replacement parts for a faulty system is easy, and most plumbers know how to install and repair Fleck systems. Last but not least, Fleck water softeners and filtration systems are easy to operate and maintain.

How Does Fleck 5600SXT Water Softener Work?

The Fleck 5600SXT is one of the most popular water softening systems from the brand. This model is essentially an updated variant of the old mechanical meter. That means few moving parts, low energy consumptions, very few problems, and straightforward maintenance.

Like most water softeners, the system uses ion exchange technology to remove hardness ions. As water passes through the resin bed, hardness ions attach to the beads (normally containing sodium, although other salts can also be used) and are trapped in a brine solution.

You will have to replace the resin bed as it gets saturated with hardness ions. Like all similar softeners, the Fleck 5600SXT produces wastewater.

Fleck 5600sxt Feature Breakdown

Build Quality & Capacity

Fleck 5600SXT is a robust water softener with excellent build quality. You can expect it to do its job for the decades to come. The installation is as straightforward as it gets, though you might want to call in a plumber if you lack basic plumbing skills.

The system we reviewed has a 48,000-grain capacity, which ensures plenty of softened water throughout your home. This system is ideal for households of up to five people, but the 5600SXT also comes in smaller and larger sizes.

Resin

One of the most important things to check when buying a water softener is the resin quality – especially if the resin bed can’t be changed.

As far as Fleck 5600SXT is concerned, the system boasts a high-capacity, 8% cross-linked resin engineered for long life. A fully programmable flow meter makes it easy to schedule regeneration cycles for maximum salt and water saving.

Programming, Settings & Maintenance

Nothing is more annoying than investing in a water softener that’s hard to set up and maintain. Luckily, that’s not the case with the Fleck 5600SXT.

The flow meter boasts an intuitive control panel that makes setting and maintaining a breeze. Four regeneration modes provide plenty of control.

A double backwash function makes this water softener a perfect choice for those living in areas with very hard water. This feature also proves to be helpful if you want to remove iron from your drinking water.

A backlit display and digital control keys also allow you to view the remaining water volume or the days to the next regeneration. Perhaps the only downside is that the system doesn’t monitor the ongoing water usage.

Water and Salt Consumption

If you’re concerned about wasting water, know that Fleck 5600SXT isn’t the most water-efficient water softener out there. The system uses around 45 gallons of water during regeneration – it can quickly drive up your utility bill if you’re using city water.

Salt consumption depends on the water hardness level. In a home with moderately hard water and moderate water consumption, you’ll have to add new salt every four to six weeks. Fleck5600SXT doesn’t monitor the salt level, so you’ll have to check it constantly.

Fleck 5600SXT Lifespan

Fleck 5600SXT is a water softener built to last. Its average lifespan is around 25-30 years, although you might have to replace the control head during this time.

Contaminant Reduction & Water Quality

Fleck 5600 SXT is not a water filtration system and doesn’t remove contaminants from water. It does remove hardness minerals, such as magnesium or calcium, preventing them from depositing on your plumbing and fixtures.

The system uses sodium salts. Thus, it may increase the sodium concentration of your drinking water. You might want to monitor this aspect if you’re on a low sodium diet.

The system improves water quality. However, suppose you’re concerned about waterborne contaminants. In that case, you should install a whole-home water filtering system before the water softener on the plumbing line.

Fleck 5600SXT Ins & Outs

Pros

  • Ideal for softening all types of hard water, including well water
  • Intelligent regeneration
  • Easy installation and maintenance

Cons

Professional vs. DIY Installation Costs

You can expect to pay between $200 and $500 for professional installation, in addition to the cost of the system. Drilling down to a well water source can cost around $1000. Add between $50 and $200 if you already have a water softener installed and need to remove it before installing the Fleck system

DIY installation is cheaper – you’ll only have to spend on basic plumbing materials. It shouldn’t cost you more than $200 to install the system yourself.

How to Use Fleck 5600SXT?

The Fleck 5600SXT water softener is easy to use. Once you’ve installed it and flushed the debris, switch from bypass to service mode and let the water fill the resin tank. When the tank is full, purge all air from the system by allowing cold water to run, then connect the unit to the power outlet.

All you have to do at this stage is program the regeneration cycles according to the manufacturer’s instructions.
