Questions And Answers

What is water conditioning?
Water conditioning is that branch of engineering that determines the chemical characteristics of a tap
water supply, as it enters your home, and treats these characteristics so as to provide water more
suitable and economical for household use.

Why is it essential to improve water quality?
Beyond being an absolute necessity of life, water is an outstanding cleaning agent. The trouble is that
nature does a lot of things with water long before you have a chance to use it in your laundry or at
your kitchen sink. You get it, as it were, second hand. Therefore, improving your water quality by
water conditioning is just as essential as any other home appliance.

Does the conditioned water have a “different” taste?
Taste is difficult to define as no two people have the same sense of taste. A water conditioner will
remove certain minerals and turbidity from the water, giving you a cleaner, better tasting water.

Will conditioned water give a cleaner, brighter wash?
Yes. For best results, you should use the proper amount of laundering agent. Keep in mind a 60 to
80% soap saving can be achieved with conditioned water. Learn to use less laundering agent
because none of the cleansing compound will be wasted as in hard water cleaning. The amount of
laundering agent you use depends on: (1) its effectiveness, (2) the volume and temperature of water,
(3) the size of the wash load, and (4) the type and amount of dirt and grime.

What effect will conditioned water have on plumbing?
Before the water was conditioned, the hard water caused a scale buildup in the hot water pipes and
water heater. Scale acts as an insulating material. In the water heater, scale reduces heat
transmission, wastes fuel and often causes heating coil and tube failure. The installation of a water
conditioner not only prevents further scale formation but will gradually remove previously formed
scale deposits. A recent study indicates that softened water offers a saving of 23% in energy cost in
the operation of a hot water heater.

Are the minerals which a conditioner removes from hard water essential to health?
No. The quantity of minerals found in hard water are not essential to good health.

Is the sodium in softened water harmful to people on restrictive diets?
Much depends on the strictness of the diet itself. When the patient is on an extremely restrictive diet,
he should drink neither hard nor softened water. Under these conditions he should have
demineralized water, distilled water, or water known to be free of sodium for drinking and for the
cooking of foods. Such patients are commonly hospitalized.

In establishing a salt-free diet for patients, physicians should not overlook the fact that even hard
water may contain appreciable amounts of sodium. To determine the amount a complete analysis of
the water is necessary.

How much sodium is added to softened water?
Each grain per gallon (GPG) hardness removed adds 7.875 milligrams (mg) of sodium to a liter of
water, which is approximately one quart. The average daily sodium intake of an adult individual is
3,000 to 4,000 milligrams and the average fluid intake is 1.6 to 2.0 liters per day. A liter is slightly
more than four 8-ounce glasses of water. Two liters per day or 8.4 eight-ounce glasses of water
amounts to a total sodium intake from a source of softened 8 GPG water of 125.16 milligrams. This is
approximately 3% of the average daily sodium intake.

There is another way to answer this question, and that depends on the hardness of your raw water.
The following table shows the additional amount of sodium consumed by drinking ONE quart of
softened water.

Initial Water Hardness                                       Sodium Added By Softening

5 Grains/Gallon                                                             37.5 Milligrams/Quart

10 Grains/Gallon                                                           75.0 Milligrams/Quart

20 Grains/Gallon                                                           300.0 Milligrams/Quart

40 Grains/Gallon                                                           300.0 Milligrams/Quart

How does this sodium content of conditioned water compare to sodium found in common


The data in the following table demonstrate the usual range of sodium in common foods.

Food                                       Amount                                        Milligrams of Sodium

It is important to note that about 2/3 of the daily water intake of any individual is through food and only
about 1/3 from water itself.
