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.

Water softeners use an ion-exchange process to remove the ions that create hard water, eliminating hard water and the problems associated with it. Automatic regeneration initiated by a high quality Fleck metered head means high efficiency, consistent water treatment, and low maintenance.Soft water will extend the life of your appliances, decrease soap requirements, and decrease the occurrence of soap scum. Softer hair and skin are also common when using water that has been softened.

Alternating dual tanks ensure maximum efficiency while providing soft water that is available 24 hours a day, 7 days a week! They are also able to handle homes with very high hardness levels or applications with water use that exceeds the capacities of a single tank system.

Controlled by the durable Fleck 9000SXT, this digital controller offers a simple user interface with LCD screen and touchpad controls. The metered control allows it to measure the amount of water used and regenerate only as needed, keeping up with your the busy demands of guests and company and slowing down when your away! The brass valve body ensures high durability even in commercial applications, and is backed by an outstanding 5-year warranty.

The durable polyglass resin tanks are manufactured by Structural USA and are backed by a 10 year warranty. The simple design allows for installation almost anywhere without being unsightly, and optional tank jackets provided added aesthetics for high visible areas. 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 350 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. 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.
The second step is to determine the needed system capacity. When sizing dual tank systems you generally want to have one tank backwash once a week. To figure out which size you need, take the hardness of your water in grains per gallon (GPG), multiply by your average daily water use (typical water use is 50-75 gallons per day), and multiply the result by 7. This will provide the approximate size of the system you will want to maximize efficiency. For example, if the water is 20 GPG and there are 3 people in the house:
20*(3*75)=20*225=4500 (grains treated per day)
4500*7=31,500 (grains treated in a week)
So in this example you would look for a dual tank system with a capacity of as close to 31,500 grains per tank as possible, in this case it would be a 32k (32,000) system. Try our softener sizing for more help.
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 9000, 9100, 9000SXT, and 9100SXT control heads?
The Fleck 9000 is an electro-mechanical controller (uses gears and pins to control the cycles) on a brass valve body. The 9100 uses the same electro-mechanical controller just on a fiber reinforced polymer valve body. The 9000SXT and 9100SXT heads replace the electro-mechanical controller with a digital LCD controller. All the control heads are metered, meaning they measure the amount of water used and regenerate based on water usage. The digital controllers have the advantage of advanced settings (including regeneration day override) and touchpad controls with an LCD display to simplify user interaction. They also have the ability to be set to a higher number of gallons between regenerations which can improve efficiency, particularly on larger systems in homes with lower hardness levels.
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.
