Fleck 9100sxt Water Softener Review (2023)

🧾 Overview

The Fleck 9100SXT Dual Tank Water Softener is a whole home water softener that comes with the added benefit of two alternating tanks that never run out of water. The system has a high flow rate to treat homes with high water hardness. It comes complete with a bypass valve to allow you to still access drinking water during maintenance.

With a digital alternative metered control head, the Fleck 9100SXT offers two tank operation, ensuring you’ll always be able to use soft water in your appliances without having to wait for regeneration. The system comes with an FAQ and installation manual for at-home installation.

An on-demand flow meter is used in the Fleck 9100STX to save water by only regenerating after a certain level of water use. The system is salt-based and uses the process of ion exchange to physically remove the hard water causing minerals, calcium and magnesium, to reduce existing scale and prevent a build-up of scale in the future. You’ll need to top up the Fleck 9100STX with sodium fairly frequently to keep it working properly.

💡 Features

• Alternating digital metered control – automatically switches between tanks to prevent running out of water.
• 2 almond resin tanks.
• Large almond brine tank with safety float.
• High capacity resin for most efficient ion exchange.
• Bypass valve to divert water to main pipe and 1 inch male connections for installation.

🚦 Performance

The Fleck 9100SXT has a continuous flow rate of 20 GPM (gallons per minute), making it an efficient salt-based water softener. The resin and brine tanks, components and connecting fittings are made from quality materials that are designed to stand the test of time, no matter how much water your household goes through.

The tanks themselves come with a 10-year warranty, and the manufacturer offers a 30-day money-back guarantee when you buy the system.

The ion exchange performance in this system is the most efficient method of softening water, as it actually removes the hard water causing minerals, thus preventing limescale deposits in the future. The system has a high grain capacity of 96,000, allowing for a large amount of hardness to be removed from water before the unit needs to regenerate.

Being a salt-based softener, the Fleck 9100SXT will waste a minimal amount of water during regeneration. Keep this in mind when comparing the system to salt-free conditioners, which generally produce no water waste at all.

🔧 Installation & Maintenance

The Fleck 9100SXT comes with installation instructions and an FAQ that answers some of the more common customer enquiries about the system. There’s also an online video, which many customers have praised for offering a good step-by-step overview of installation. That said, as the system requires connecting up to your water line, you will need plenty of patience and some basic plumbing skills to install it, and you may prefer to leave the task to a plumber.

Not all of the Fleck 9100SXT’s components are designed to last for life. You’ll need to replace the resin after around 5 years – and you’ll get a 5-year warranty on this, with a free replacement if your resin doesn’t last this long. You’ll also need to top up the salt in your tank every time it falls low. This generally needs to be done every 8 weeks to ensure your system continues to work properly.

On top of maintenance, you should clean the Fleck 9100SXT to get rid of any grime from the tanks and prevent system breakdowns. Rinsing out the tank with fresh water is usually enough to remove the bad stuff, but check your user manual for specific cleaning instructions.

📝 System Info

The Fleck 9100SXT is a salt-based softener, and uses the process of ion exchange to remove hardness causing minerals from water. During ion exchange, when water flows through the resin beads, sodium minerals are switched with the calcium and magnesium ions, eliminating them entirely from water. This gives the most effective soft water results throughout the household.

One of the biggest benefits the Fleck 9100SXT offers is scale prevention. The soft water produced by the system won’t deposit limescale on your appliances or in your pipes. Additionally, soft water can also produce a better soap lather, helping you to save money with your washing machine and dishwasher use.
