Hard water—do you have it?
Before you can decide what to do
about hard water, you need to know
if you have it and, if so, how hard
it is.
●
If you live in a municipal area,
contact your water company.
●
If you live in a rural area, or in
some suburban areas, contact your
county agent.
The answer will be “you have ‘so
many grains’ per gallon” and
means this:
O to 3 grains per gallon–SOFT
4 to 10 grains—HARD
11 to grains–VERY HARD
20 grains and
EXTREMELY HARD
If your water is SOFT, you have
no problem. You can use soap or
detergent as you prefer and forget
all about hard water. If you have
HARD water—less than 10
and you use phosphate detergent,
you also have no problem.
But, if you have more than 10
grains, you will need to soften your
water with either. . .
1.
An installed water softener in
your home, or
2. The use of a packaged water
softener.
For information on water
softeners, see guide below.
