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
11 to 19
20
and over—EXTREMELY
If your water is
you have no
problem. You can use soap or
detergent as you prefer and forget
about hard water. If you have
water—less than 10
grains-and you use phosphate
detergent, you
have no
problem.
But, if you have more than 10
grains, you
need to soften your
water with either...
1. An
water softener in
your home, or
2. The use of a packaged water
softener.
For information on water
softeners, see chart below.
