Hard
Before you can decide what to do
about hard water, you need to
you have and, if so, how hard
it is.
●
If you live in a municipal area,
contact your water company.
●
If you live 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
to 19 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
grains—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 water
softener.
For information on water
softeners, see chart
below.
