Questions & Answers
What is Hard Water ?
Answer: The term
hardness refers to the quantity of dissolved calcium and magnesium
in water. These minerals, which come primarily from limestone type
rock formations, are found to some degree in almost all natural
waters. Calcium and magnesium cause problems for two principal
When the water is
warmed, they precipitate out of solution and form a hard, rock-like
scale. This scale accelerates corrosion, restricts flow, and reduces
heat transfer in water heaters and boilers.
When they combine
with soap, they react to form a curd, which interferes with
cleaning, dries out skin, and leaves deposits on plumbing and
clothes (bathtub ring; ring around the collar). The minerals in hard
water gradually settle out forming a hard scale. Scale centimeters
thick can build up over time in hard water areas. Scale build up
will eventually clog pipe, and can decrease the life of toilet
flushing units by 70 percent and water faucets by 40 percent
according to a report published by the American Water Works
Association (AWWA). Hardness scale can also shorten life of washing
equipment, dishwashers, and clothes washers by as much as 30 percent
according to the AWWA report.
Hardness is measured in
parts per million (or the equivalent mg/L) or in grains per gallon
(gpg). Note: if the water analysis is given in ppm as CaCO3 then 1
gpg = 17.1 ppm. There is no established limit for the acceptable
level of hardness in water, but it is generally considered to become
problematic at around 3 gpg.
Levels of hardness are
referred to as follows:
Soft Water: 0 - 1
grains per gallon (gpg)
Slightly Hard Water: 1 - 4 grains per
Moderately Hard Water: 4 - 7 grains per gallon
Hard Water: 7 - 10 grains per gallon (gpg)
Water: Over 10 grains per gallon (gpg)
1. How does the Whole
House No-Salt RDWS-Sierra Package work?
First, water enters the
premium carbon prefilter to remove chlorine bad tastes and odors.
Second, clean water now enters the hard water scale
prevention media system. This media transforms calcium ions (hard
water) into calcium crystals , which are stable and cannot attach to
pipes, surfaces, hardware, or heat exchanger components. These
crystals are so small they are easily rinsed away by water flow.
Note: this is not a spot free system - A simple damp cloth (if at
all) is more than sufficient to remove any residual mineral
2. Is the RDWS-Sierra Package a Water Softener ?
No. To "soften water"
you actually have to remove the calcium and magnesium hard water
minerals. The RDWS-Sierra Package does not remove the
calcium or magnesium. These systems are alternatives to salt based
water softeners and perfect for customers who live in banned
water softener areas or who just want to Go Green ! The
media transforms calcium ions (hard water) into calcium crystals ,
which are stable and cannot attach to pipes, surfaces, hardware, or
heat exchanger components.
3. I see other
companies advertising similar systems calling them "saltfee water
softeners" no-salt water softeners" and "saltless water softeners"
why don't you?
The RainDance Water
Systems name is synonymous with quality and reliability.
We offer and
specialize in both salt less water conditioners and sodium optional
water softeners. We are proud to say that we have many happy and
satisfied customers throughout the World using both of these
we choose to sell our
non-salt water conditioners correctly by not calling them "water
softeners" and want you to know that your water will not test soft
due to the calcium & magnesium being left in the water and you wont
get that slippery feel to the water.
4. Are your RDWS-Sierra Package environmentally friendly?
Yes. These systems do
not require electricity, no brine water discharge or backwash water,
no control valve, no drainline, no waste water, no salt, saves water
5. Will your
RDWS-Sierra Package provide whole house drinking water filtration?
Yes. Our RDWS-Sierra Package
provides whole house chlorine bad tastes and chemical
odor filtration at every tap! We even include an easy do it yourself
chlorine test kit with each system !
6. Will the conditioned
water make me feel slimy?
No. there will not be
the slippery feel on your skin when you shower or bathe. This feel
is typically associated with salt based water softeners.
7. Can your RDWS-Sierra Package be used to treat well water sources?
No. The RDWS-Sierra Package is designed to treat hard water, chlorine bad tastes and odors typically associated with
city municipal water sources.
8. What type of
maintenance can I expect to have with your RDWS-Sierra Package?
We consider our
RDWS-Sierra Package a virtually maintenance free system. We
recommend replacing the carbon prefilter approximately every 6-9
months or when needed. And the hard water antiscale media to be replaced
approximately every 3-5 years or when needed.
9. Can I have a
plumber install your RDWS-Sierra Package or can the home owner
provide installation ?
A plumber or do it
yourselfer can easily
install the RDWS-Sierra Package and you will love the
fact that you do not need to bother with a drain line or
electricity. We also provide detailed installation instructions
which allow DIY with basic plumbing knowledge to install themselves.
