Fleck 64,000 Water Softener

Fleck 64,000 Water SoftenerHave you ever heard about hard water? You might have come in contact with it without even knowing. Hard water is a term used to describe water that is filled with minerals, like magnesium and calcium, and while you won’t see these minerals to know that the water is hard, you will instantly realize that you’re dealing with hard water once you use it.Unfortunately, hard water tends to clog water pipes due to the mineral accumulation left behind and it also prevents soaps from lathering well.So, when you see these signs,then you are most likely dealing with hard water.

Luckily, a special type of filter, called the “Water Softener” was developed to eliminate the hardness in hard water by removing the hard elements in it before it is circulated for use. In this article, we will be reviewing the Fleck 64,000 Water Softener. Manufactured by Fleck, which with more than 25 years of consistent brilliance, has risen to the top of the industry, you can rest assured that this is a high-quality product.But, while the Fleck 64,000 Water Softener is an affordable, high-end product, it is only suitable for people with extremely hard water.

However, in addition to the Fleck 64,000, there are other excellent models of water softeners available, and another similar product that also caught our attention during our research is the Aquios FS-220 Salt-Free Water Softener. Featuring a bit smaller size compared to the Fleck 64,000 and given that its operation doesn’t require the use of salt, this product is a bit different.Of course,that doesn’t take anything away from their similarities, but most of our focus will be placed on the Fleck 64,000 in this article.

Key Features

Knowing what to expect in a product is important before you make your purchase decision. We have done some research and you will be reading about the features of the product in subsequent paragraphs.

Method of Water Softening

The Fleck 64,000 works by swapping unpleasant minerals like calcium and magnesium with harmless sodium ions. This is done in a process called ion exchange, which ensures that the water becomes softened and better for use.

Metered Regeneration

It is important to note that because of the ion exchange, the appliance will sooner or later reach its limit and self-cleansing will have to be done. During the process of self-cleansing, the machine is unusable, which can be a problem during your first period of using the product. However, this problem can be eliminated by studying the machine and knowing how long it takes to regenerate so that you can prepare ahead. In addition, the Fleck 64K allows you to pick the regenerating start time when it reaches a certain capacity, which is more preferable because you do not have to wait until it reaches its full capacity.

Digital Monitor

This appliance has a digital monitor with different modes and settings, which include how much soft water remains; diagnostics indicator;setup for regeneration,capacity,and time; and other programmable options. Apart from these modes or settings, the digital monitor has 48-hour reserve energy to counter situations of unexpected power outages. The interface is also user-friendly and can easily be grasped by anybody.


To assure you that the Fleck Company makes quality products, the company has put a warranty of 5 years on the valves and 10 years on the tanks. This further boosts the confidence of the buyers as there are not many companies that can give that much warranty time on their water softeners.

Resin Capacity

The Fleck 64K water softener has a resin capacity of 1.5 cubicfeet, which shows how many harmless minerals are available for exchange. The regeneration process of the water softener will begin immediately when the resin capacity is fully used. It is noteworthy that the amount of the resin is enough to serve four people easily and the usage can be rationed among a group of six.

Brine Tank

The brine tank of the water softener aids the cleaning of the resin when the regeneration process is on. The brine tank of this particular water softener measures 15” x17”x33” in size. It can hold up to 250 pounds of pelleted salt, which is enough to last four people for more than 3 months. Furthermore, the tank also prevents overfilling because of its safety float feature. To round it up, the tank features an overflow drain that reduces the chance of creating a mess during filling.

Water Flow Rate

The water flow rate of this appliance is over 18 gallons per minute (GPM), which should be more than enough for most homes. However, commercial facilities like restaurants and hotels might need more water and they might have to install an additional water softener.

Great Customer Service

The customer service was said to be great and that the people in charge of customer service try as much as possible to reply to complaints or questions in good time. In addition, solutions to problems were also proffered in no time. It was also hinted that the customer care officials are very friendly and ready to assist customers.

Final Words

From everything you’ve read in this article about the Fleck 64,000 water softener, you can agree with us that it is a good product. It promises multiple functions, quick water-softening action, and a large brine tank. Interestingly, the manufacturers also made the product with the thought of unexpected power failure in mind because it boasts a 48-hour power reserve. Additionally, this product can be easily installed through the step-by-step instructions provided by the manufacturer.

While some might disagree with us, but in comparing the Fleck 64K water softener with the Iron Pro 64K Combination Iron softener, the Fleck 64K looks like a better value for the money. This is because they have almost the same functions and the Fleck 64K is still very much cheaper. In addition, the Fleck 64K can comfortably serve more than a family of 4, but using the Iron Pro 64K product for a family of five will be a big stretch.

We hope you have learneda few things about the Fleck 64K water softener from this article. The quality is assured and this is reflected by the 5- and 10-year warranty on the valve and tank, respectively. The product is also not expensive in comparison to other products in the same function range. In conclusion, we have to chip in that this is one product on which you won’t regret spending your money.
