Fleck Water Softeners

By bill_r / December 15, 2016

Pentair Residential Filtration Company, the company behind the Fleck water softener series, has been around for 40 years so you can be assured of the quality of their products. In fact, they are so confident in their products, they offer a 5-year warranty on most models. This is one of the longest warranties in the industry.

The long history of the company also ensures that it will be easy to find parts when needed and if any maintenance or repairs are necessary you won’t need to waste time trying to track down someone who knows the unit.

Benefits of Fleck Water Softeners

Fleck water softeners are consistently the top rated water softeners in the industry. One of the things they are known for is their hydraulically balanced piston seal spacer technology, also known as “on-demand” valves, that regulate the water flow based on how much you use it. For additional information on regeneration, checkout this Popular Mechanics page. This allows them to be environmentally friendly, as well as effective at softening your water, because it only regenerates the water when you need it. This helps to avoid excessive waste of water, salt and electricity.

Fleck valves have easy to use digital displays and fit most standard tanks. Surprisingly, Fleck units are also some of the most affordable, especially considering they are the best on the market.

So, now that you’ve decided to invest in a Fleck water softener, which model should you choose? Here are the best Fleck water softeners so that you can decide which one will work best for your needs.

Fleck 5600 SXT


The Fleck 5600 SXT is one of the most popular Fleck models and receives the best Fleck water softener reviews. It is a 48,000-grain system and will treat 12 gpm flow rates, which is suitable for a household of 3-6 people with moderately hard to very hard water. The 5600 SXT will effectively soften your water and remove the calcium and magnesium ions that cause lime scale.

After installing this unit, you will immediately notice a decrease in how often you need to clean your shower and sinks and your hair and skin will be softer and healthier. Also, it will extend the life of your plumbing and appliances as it will end the lime scale buildup in your pipes. Despite how hard it works, the 5600 SXT is a quiet unit, so aside from all the benefits you won’t even know it’s there.

Fleck 7000 SXT


The 7000 SXT model has all the great features of the 5600 SXT, but with an increased water capacity. The size of the internal water passages of the 7000 SXT is slightly larger than the 5600 SXT, allowing for greater flow rates and larger water tanks.

The 7000 SXT will treat a flow rate of up to 35 gpm. Like most Fleck models, the 7000 SXT is easy to install with detailed instructions that can be supplemented with multiple how to videos on YouTube. However, if you choose to hire a professional plumber for install, the installation should not take more than an hour.

Fleck 9100 SXT


The main benefit to investing in the 9100 SXT is that it has a twin tank for increased capacity, which will provide you with softened water 24 hours a day. Where some units may give you unsoftened water during regeneration (often overnight), the double tank on the 9100 SXT acts as a back up tank and will allow you to avoid this. The increased capacity also comes with high quality valve bodies that are practically indestructible, so maintenance on the unit is minimal. If you have a large household or a stronger flow rate, you may want to consider the Fleck 9100 SXT.

Choosing the Best Fleck Water Softener

As you can see, you can’t go wrong with a Fleck water softener. Each model provides its own benefits, but the best Fleck water softener for you depends on the needs of your household.

  • Small Households - For small household or slow water flow rates, the Fleck 5600 SXT will be more than enough to meet your needs.
  • Medium Households - For larger households with stronger flow rates you may want to consider the 7000 SXT.
  • Large Households - If you need your water to be soft 24 hours a day and can’t afford to let the unit regenerate overnight, the 9100 SXT will be the best unit for you.


Having hard water can be frustrating and can make your life more difficult, but you can be confident that you can get the best Fleck water softener to solve all your hard water problems.

Hi and welcome to my website. I'm Bill Robertson and I worked my way through school as a handyman. The skills I learned have been useful as I've made changes to my own home. As a father of a 3 children, having a healthy water supply is important. Because the Central Texas well water was so hard, a water softener and reverse osmosis filter were critical. The water softening process was interesting and resulted in such a difference in water quality that I wanted to know why. This website is the result. Central Texas is famous for its hard water and I likes sharing what I learn experience with other readers.
