Saves Water-Heating Energy, Helps Water-Using Appliances
Soft water reduces the formation of rock-like hard water scale which encrusts water heaters, hot water
pipes, shower heads, and water-using appliances. This scale can cause premature maintenance and
failure.
Elimination of hard water also provides substantial energy savings because scale acts as an insulator,
wasting electricity or gas used to heat water.
Savings Galore
A water conditioner is frequently referred to as "the appliance that pays for itself". You'll find that
your savings on soaps, detergents, cleaning aids, and personal care products will help your family's
household budget. And if you place a price on your time, you'll be most happy with the time saved by
your new family servant.
Water For Lawns And Household Plants
If possible, lawn sprinkling faucets should be supplied with hard water primarily because it is
uneconomical to soften so much water.
Household plants are much more sensitive than lawns with respect to the kind of water which is best.
First, because they receive no rainfall and, second, there is little or no drainage of the soil. Preferably
they should be watered with rainwater or water which is low in mineral content such as distilled or
demineralized water. Softened water is not recommended for house plants because a build-up of
sodium in the soil may interfere with efficient absorption of water by the plant root system. Additional
information may be obtained from your independently operated Culligan dealer.
Why Water Gets Hard And How It's Softened
All of the fresh water in the world originally falls as rain, snow, or sleet. Surface water is drawn
upward by the sun, forming clouds. Then, nearly pure and soft as it starts to fall, it begins to collect
impurities as it passes through smog and dust-laden atmosphere. And as it seeps through soil and
rocks it gathers hardness, rust, acid, unpleasant tastes and odors.
Water hardness is caused primarily by limestone dissolved from the earth by rainwater. Because of
this, in earlier times people who wanted soft water collected rainwater from roofs in rain barrels and
cisterns before it picked up hardness from the earth.
Some localities have corrosive water. A softener cannot correct this problem and so its printed
warranty disclaims liability for corrosion of plumbing lines, fixtures or appliances. If you suspect
corrosion, your Culligan Man has equipment to control the problem.
