We always recommend a water filter in front of all brands of water softeners. Why? Others might say their softener doesn't need a filter in front of it. Ours doesn't either! No matter what brand of softener that you buy, a 30 micron or smaller sediment filter in front of any brand softener will definitely extend the life of that unit.
"What is hard water?"
Hard water is defined as having more than 1 GPG (grains per gallon) of dissolved
minerals in it (usually calcium, magnesium carbonate, and/or manganese).
"How is hard water measured?"
Hard water is usually measured in either PPM (parts per million) or GPG
(grains per gallon).
17.1 PPM or Mg/L = 1 GPG
or
PPM or Mg/L divided by 17.1 = GPG (grains per gallon)
"How can I tell how hard my water is?"
You can either have it tested locally.
"Why does the water softener have to add salt to the water?"
The softener works by passing the hard water through resin beads which
have soft sodium/potassium ions attached to them. While the water is in
contact with the resin beads an ion exchange takes place with the hard
mineral ions (typically calcium and/or magnesium) trading places with the
soft sodium/potassium ions. After a period of use the sodium ions are
depleted being replaced by calcium and magnesium. The resin then needs to
be regenerated with the sodium ions so the resin will again be able to
exchange the hard for the soft.
"What is the difference between a water softener, a water filter, and
a descaler?"
A water softener is a water treatment system where the calcium and magnesium
carbonate (the minerals responsible for the hard water) which are dissolved in
the water are replaced with
either sodium chloride (salt) or potassium chloride. This is different from a water
filter in that filters will generally remove chlorine, pesticides, bacteria
(in some cases), and suspended particles (sand, sediment, etc). A filter
will not remove dissolved solids
(which are responsible for hard water). A descaler does not remove dissolved
solids, it attempts to prevent the solids from being deposited inside pipes,
on fixtures, etc.
"Why would I want to soften my water?"
It greatly reduces the scaling of pipes, faucets, pots, glasses, tubs, etc.
You will use less laundry soap, dishwashing soap, hand soap, etc.
The water is more pleasant to wash with, less soap scum.
"Ok then, why wouldn't I want to soften my water?"
If you're using sodium chloride (salt), then the softener will add a small
amount of sodium to the water. For most people this is not a problem. However,
if you're on a sodium restricted diet, we would recommend a seperate faucet
in the kitchen that dispenses un-softened water for drinking.
Some people take a while to get used to the feel of softened water.
"Someone told me that softened water feels 'slimy'."
When you wash your skin with hard water, there is a layer of soap and
minerals that is left on your skin. This is what causes the supposed
'squeaky clean' feeling. With soft water, the soap is completely rinsed
away leaving just the natural oils your skin produces.
"I've heard that a water softener adds sodium to my water supply. Is this
true?"
Yes. A household water softener removes the hardness minerals - calcium and
magnesium - from water and replaces them with sodium.
"How much sodium is added to the water by the softener?"
That depends on the hardness of the original water. This table shows the
additional amount of sodium consumed by drinking one quart of
softened water.
Initial Hardness Sodium Added 1.0 grains per gallon 7.5 milligrams/quart 5.0 grains per gallon 37.5 milligrams/quart 10.0 grains per gallon 75.0 milligrams/quart 20.0 grains per gallon 150.0 milligrams/quart 40.0 grains per gallon 300.0 milligrams/quartAs a comparison, one slice of white bread has 161 milligrams of sodium; 3/4 cup of canned baked beans = 1130 milligrams; 1 tablespoon of catsup = 204 milligrams; 1 medium frankfurter = 610 milligrams; and 1 cup of whole milk = 127 milligrams. Even a common Alka Seltzer tablet contains 532 milligrams of sodium.
"Should I worry about corrosion from the salt in the water?"
No. Over a long period of time it may have some effect on exposed steel
surfaces. Most of the metal in a home that comes in contact with softened
water is either coated, painted, or stainless steel. All which would be
unaffected.
"Do I have to use salt?"
Most stores that sell softener salt will also sell a salt substitute
(potassium chloride). This is just as effective as the regular salt, but
adds potassium instead of sodium. The downside is that potassium chloride
costs between 3 and 4 times more than the regular softener salt.
"Will a Reverse Osmosis system remove the salt from the softened water?"
Most brands will remove 95%+ of the salt from the water.
"What difference does size make?"
The size of the softener (rated in grains) in combination with knowing
your hardness level will tell you how often it will regenerate, and
consequently how often you will have to add salt. Our unit has a capacity
of 40,000 grains.
As an example:
If you have a family of four and you hardness level is 10.
Divide the 40,000 by your hardness (10), giving you 4,000 gallons of treated
water. The
average person uses about 50 gallons per day so divide the 4,000 by 200
(50 gallons x 4 people). This gives you 20 days between regenerations. Our softener uses about
12 lbs of salt per regeneration, so if you start out with a full brine tank
(350 lbs) it should last you over a year and a half before you have to add
salt again!
How's that for low maintenance?
"How much water does it take to dissolve 12 pounds of salt?"
One gallon of water will dissolve 3 pounds of salt. So for 12 pounds of
salt, at least 4 gallons of water should be in the brine tank.
"With a flow rate of 13gpm, just how much water is that really?
How much water do most fixtures use?"
A toilet will normally use 2-3gpm, a shower 1 1/2 - 3, a bathroom or kitchen
faucet 2-3, a dishwasher 2-4, a washing machine 3-5. When you start running
more than one fixture at a time, they add up quick and those extra gallons from
1" waterways can make a difference.
"Why would I spend extra for '1" waterways' when I only have a 3/4"
main?"
Even if you have a 3/4" main line, having true 1" waterways will significantly
reduce the friction loss that any softener produces. Yes, this might be
"overkill" for some, but if gallons per minute are important to
you, then it would definitely be worth the extra money.
"What makes your softener better than others that charge as much as four
times the price?"
All softeners, regardless of price, should soften your water (i.e reduce the
hardness to 0 grains). The question is how long will the unit last? How often
does it regenerate? How large is the grain capacity? What is the warranty?
How long has the company been in
business? Does the softener regenerate based on time rather than how much
water has been used? How easy is it to change the settings and service the
unit? How quickly can you get your questions answered and your problems
solved?
"Why do you recommend a two tank system over a one tank system?
Salt water is corrosive. If you live by a beach and have a car, you see this
all the time. On a one tank system the controls are very close to the salts.
We feel that it's far superior to keep the electronics away from the corrosive
effects of the salt.
"I read somewhere that drinking soft water might be related to hearts attacks.
Is this true?"
There is currently a medical controversy over what effect, if any, drinking
hard or soft water may have on heart disease. In some areas with
naturally soft water, residents seem to suffer more from heart disease.
In other areas, there appears to be no difference between drinking hard or
soft water. A number of researchers feel that some other constituent of
water - not hardness or softness - may be responsible for the variations in
heart disease figures in different areas of the country.
"What's the difference between naturally soft water and the water from a
water softener?"
There's a great deal of difference! Naturally soft water is generally acidic
and contains very few dissolved minerals. This tends to make the water quite
corrosive to pipes and plumbing.
The water from a water softener is more like the raw water from which it is
made. It is usually alkaline rather than acidic, and contains moderate amounts
of dissolved minerals. Thus softening hard water in the home should not
significantly affect corrosion.
"Will a softener remove iron/red stains?"
In many cases it will, see here.
"Will a softener remove tannin?"
It can. By replacing the typical CATION media in the softener tank with
an ANION resin, it will probably remove tannin.
"I've read that the softener capacity should be large enough so that
it should not regenerate more than every two days. Is there an ideal
period between regenerations?"
"Do long periods between regenerations (say a month) have any negative
effects on the softener?"
A water softener should be regenerated when the softener has reached
its capacity and is unable to keep exchanging the hard ions for the
soft ions. How often a water softener regenerates is dependent on how
many grains per gallon of hardness is present in your water and the
capacity of your water softener. If the capacity of the water softener
is 40,000 grain, and you have 10 grains per gallon of hardness, then
your softener would regenerate after 4,000 gallons of water had passed
through it. How quickly you would use 4,000 gallons of water would
really depend on your water usage. Long periods between regenerations
would not have any effect on the softener if water is being used and
traveling through the softener. If you are on vacation and water is not
being used, sitting in the softener, then the water in the softener
could be bacterialogically fouled. Fouling would depend greatly on
condition of your well water. The softeners we sell are able to be set
up (by the customer) for a calendar override. A calendar override would
cause the unit to regenerate after a predetermined period of time. It
can be set for between 0 and 15 days. Another way would be that whenever
you get back from a long vacation just put a little chlorine in your
brine tank and push the manual backwash.
"What is the valve assembly made of?"
The valve is made of Noryl® plastic.
"Does the resin tank have to be right next to the brine tank?"
No, they can be up to 20' apart.
