Product Description

Hard water causes a multitude of problems. Scale build-up restricts pipes, builds up on fixtures, and can degrade appliances. Hard water spots are also common on dishes and many other surfaces. The ions that comprise hard water attract soap molecules, requiring more soap to get the job done. This also causes an increase in soap scum and can prevent the removal of dirt and bacteria when bathing. Hard water has also been know to cause hair and skin to be brittle and dry.

Iron causes rust buildup that causes appliances, fixtures, clothes, and even hair to turn a red-orange color. Manganese causes a black slime buildup, usually seen in toilet tanks and other areas where water is allowed to stand. Hydrogen sulfide (sulfur) is a common contaminant detectable by a noticable -inchrotten egg-inch odor

Water softeners use an ion-exchange process to remove the ions that create hard water, eliminating hard water and the problems associated with it. Standard softening resin will only remove a small amount of clear water (ferrous) iron only. Fine mesh resin improves that capacity to a moderate level (8 ppm or less) of both clear water and red water (ferric) iron. Adding KDF85 media allows it to treat hydrogen sulfide (sulfur) as well as chlorine and heavy metals

Controlled by the digital Fleck 5600SXT, efficiency and control come together in a user friendly interface. On demand regeneration keeps up with high demands and conserves water and salt when demand is low. This results in consistent treatment and higher efficiency. Backed by an outstanding 5-year warranty and built around the tried and true 5600 valve, these heads are sure to last for years to come.

The durable polyglass resin tank is manufactured by Structural USA and is backed by a 10 year warranty. The simple design allows for installation almost anywhere without being unsightly. NOTE: Tank color may vary from the one shown

This system comes complete with a brine tank that includes a float assembly for added reliability and peace of mind. Capable of holding up to 250 lb of salt, the large capacity of this brine tank requires infrequent addition of salt and reduces maintenance. NOTE: Color and design may vary from the system pictured

Simple connections and simple set up make this system great for DIYers. Detailed online installation instructions offer a step-by-step guide on proper installation and set up of the system on installation

Q. What is a water softener?
A water softener is a special filter that uses a process called ion-exchange to remove water hardness, also know as CaCO3, from your water. As the water passes through the softener, univalent sodium or potassium ions on the softening resin exchange with divalent calcium and magnesium ions in the water, eliminating water hardness. Eventually the media in the softener (called softening resin) has exchanged all of its sodium or potassium ions, at which point it will no longer be able to remove any more water hardness. This is why the system regenerates. During this process the system runs a brine solution (water and either sodium or potassium chloride) backwards through the softening resin. This concentrated solution forces the trapped calcium and magnesium ions off the resin and down the drain, replacing them with the sodium or potassium ions needed for softening. With the Fleck control heads, this process is automatic, and only as needed!
Q. What does the grain capacity mean?
Water hardness is usually measured in grains per gallon (GPG). (Some places use parts per million [ppm] or milligrams per liter [mg/L]. To convert your ppm or mg/L to GPG simply divide by 17.1 [Example - 200 ppm or mg/L is equal to 200 / 17.1 = 11.7 GPG]) The grain capacity of a system is how many grains of hardness your system can remove before it needs regenerated. A 32,000 grain or 32k water softener will remove 32,000 grains of water hardness. From that you can determine how many gallons of water you can go through between regenerations. If you have a 32k softener and your water is 15 GPG hard, you can go through 32,000/15=2,133 gallons of water before your softener is exhausted and needs regenerated.
Q. What size system do I need?
There are 2 main factors in determining the size you need: water usage and water hardness. Here is a general guideline on sizing your system: 32k system - 1-2 people, average water use and low hardness (under 15 GPG) 48k system - 3-5 people with average water use or moderate hardness (15-45 GPG) 64k system - 5-7 people with average water use or high hardness (45-65 GPG) Service Flow Rate is the maximum amount of water, in gallons per minute (GPM) that a given system can effectively treat. Always size a system based on water usage first, a system undersized for your water usage may not always filter effectively and will wear out faster.
Q. Are there systems that don't use salt?
Yes, we carry a high quality salt free water conditioner that eliminates hard water problems. Our Scale Sentry system utilizes a specialized media called Filtersorb to provide the same benefits a standard softener offers without the use of salt. In addition, beneficial minerals are left in the water and existing scale is removed as well! In our experience our systems outperform other salt free units, including the "magnetic" and electric systems that are widely available.
Q. Should I be concerned about the salt a water softener puts in my water?
No. The amount of salt put into your water by a water softener is minimal. In fact, in most cases it is low enough that water ran through a softener is still considered "low-sodium" by the FDA. If you want to avoid adding additional sodium to the water all our water softeners can be used with potassium chloride instead of the traditional sodium chloride. If you want to safe drinking water, our drinking water RO systems can turn your ordinary household water into bottled quality drinking water.
Q. What are the differences in the Fleck models 5600 and 5600SXT control heads?
The Fleck 5600 is your basic mechanical control valve. It does it's job in the most cost effective way possible. It is a metered head so it measures how much water you go through and regenerates based water usage. Due to the mechanical limitations on the head it can only be set to 2,100 gallons, at that point it has to regenerate, so some efficiency can be lost depending on the system size and your water hardness. This head is ideal if you are looking for the lowest cost option. The Fleck 5600SXT works similar to the standard 5600 but uses a digital interface instead of a mechanical one. This makes setup easier, and with the digital control it can be set to go through up to 9,999 gallons of water between regenerations. The 5600SXT can be more efficient that the 5600 because of this, especially in larger homes with lower hardness levels. The other advantage the 5600SXT has is adjustable regeneration cycles, while in most cases these settings won't need to be adjusted, with the 5600SXT the option is there should you ever need it.
Q. What kind of maintenance does this system require?
The only regular maintenance a water softener requires is adding salt to the brine tank, and occasionally cleaning the brine tank.

    AFWFilters is a great business to deal with. The salesperson took the time to answer my questions and he offered relevant guidance to help me choose the correct water softener. 5 stars for the business and 5 stars for the Fleck 5600sxt. This new unit replaced a very old system and I am amazed at how far they have come in regards to the quality and technology. The system was very easy to install and program. I made moderate plumbing skills but was able to easily follow their guide. Well done AFWFilters!

    Very good system

    Posted by Unknown on Sep 26 2015

    I needed to replace or repair a CSI (out of Ashland, Ohio) water system I installed in 2004. The control head started leaking. I could have replaced the head and refreshed medial and resin, but the unit never seemed to perform as well as I would have liked. I decided to try a new unit and not bother with a repair job. While doing some research on what was available, I came across Abundant Flow and was impressed with the wide range of products. I determined that the Iron Pro Plus 48k Fine Mesh Water Softener PLUS KDF85 with Fleck 5600SXT was the best fit for what I needed. In my “younger days” (now 61), I owned a water well drilling business and somewhat knowledgeable of water systems. In fact, this water system is for a well that I drilled for my parent’s home. The water is very hard and has considerable iron content. Being an old water system and never flushed and cleaned, it has your typical sulfide type of smell. I thought the extra fine mesh would help the iron content and the KDF85 would help the smell. The original softener helped little on both counts, but in all fairness, the softener (48k grain) was just a typical softener. The new unit arrived within a few days in several boxes (medial and resin in separated boxes). After checking for any damage, everything seemed to be in order and no noticeable damage. Being in separate boxes, it was easy to cart down into the basement. As instructed I read through the instruction. I hooked up a hose to the pressure tank to have a supply of water while installing the softener. Never liking to work with old plumbing I cut out the old bypass valves and scooted the old softener out of the way. Personally, for those that may have older water systems with old valves, I would recommend incorporating compressing fitting ball valves at any source of possible water coming in or back into the lines. This simply makes it easier to do any soldering without having to worry about water leaking into the lines. Following the instructions, I added water, gravel, resin and media (thank you for the blue funnel!!). Finished filling the tank with water, attached the control head. Did a final adjustment to the position of the tank and cut, fitted and soldered the unit into the water system. I did not use the provided salt tank. I used the existing one. Two reasons, it looked far better. The provided one did not look all that sturdy, but I am sure would have worked fine. The existing one was round solid and functioning just fine. The second reason, I just did not want to bother with removing the salt. After the hoses were attached, I followed the instructions to prep and run a manual cycle. The buttons on the control head did not function very easy. It was somewhat difficult to press and hold the buttons together to get it to go into the proper mode(s), but once I did, it was easy to move through the settings. Once it was fired up and never having a digital unit before, it was kinda fun to watch (had nothing else to do at the time)it go through the count down and go into the next portion of the cycle. After the cycle was completed, I ran water in the house for quite a while. Now for the test. I had my wife taste test the water. If anyone is picky about how water “tastes” it is her. Her response? “This is really good. I can drink this and no smell. It is better than ours.” (We have city water also with a CSI softener). I can honestly say that to my taste, it was very good drinking water and I could not detect a sulfide smell. Since it is a usage based system, I am interested in going back over in a few weeks and see the amount of salt usage. It is only my mother living there now and usage is very low. I have initially set the forced cycle to be 7 days. If salt usage seems a little higher than expected, I may up it to 14 and see if there is any difference. If not for the salt tank and button control issues (however minor), I would have given a 5 (which I reserve only for no issue products). If the condition of the water continues to be as good as first installed, this is a great unit and I would not hesitate to recommend it to others. Will look to this company when I need to replace mine.
