Fleck Water Softener Buying Tips

Although the differences between the water softening Fleck systems are subtle, there are still some features that one would have to consider when buying a Fleck Water Softener.

  • Budget

A water softener can be very tricky when it comes to price, and so you would have to purchase one that is well within your budget. Luckily, the Fleck Water Softeners are affordable and all have a wide range of different prices depending on what you can afford unlike some other water softener prices. It is advisable to avoid purchasing a system that is quite  large for your family so you don’t waste money.

At the same time, if you have a large family, buying a small Fleck system would not benefit you and your family. You should also consider installation costs if you don’t plan on setting up the system yourself, and maintenance fees. Even with this, before going out to get your Fleck water system, plan a budget and ensure that you stick to it.

  • Size

As you might have noticed, the Fleck systems vary from large to small. This is a very important feature to also consider when purchasing a Fleck system. You must purchase a system that is able to meet the needs of you and your family without breaking down or losing water pressure.

With this, a 2 bedroom house with at least a family of three will be okay with 48k holding capacity but a larger family would need more, like a dual tank system. Ensure that you don’t purchase a system that is too large for your family because this would waste money and water. Also, a system that doesn’t provide enough water would be almost useless and frustrating to use.

Also, the system you purchase should have straightforward water softener installation processes.

  • Flow Rate

The flow rate of the Fleck Water Softener that you want to purchase is also something that you should determine before purchase. The flow rate of the water softeners Fleck are between a range of 12 to 28 gallons per minute. A small home or a small family would be okay with 12 gallons per minute or a little bit more, but for large families where the water is being used at the same time and constantly, 28 gallons per minute would be an ideal choice.


If you have a problem with hard water in your home, you cannot go wrong by choosing one of the water softeners Fleck mentioned above. The Fleck 5600SXT would be a great choice for you, although if you have a problem with iron, you can try the Iron Pro 2 system.

All in all, Fleck is a great brand that would provide you and your family with safe and healthy drinking soft water.
