SECTION 2
HOW YOUR WATER SOFTENER WORKS
2B. SOFT WATER SERVICE AND REGENERATION
SERVICE
When the softener is giving you soft water, it is
called “Service". During service, hard water
comes from the house main water pipe into the
softener. Inside the softener resin tank is a bed
made up of ttiousands of tiny, plastic resin beads
(FIG. 4). As hard water passes through the bed,
each bead attracts and holds the hardness
minerals. This is called ion-exchanging. It is
much like a magnet attracting and holding
metals. Water without the hardness minerals
(soft water) flows out of the softener and into the
house soft water pipes.
After a period of time, the resin beads become
coated with hardness minerals and they have to
be cleaned. This cleaning is called regeneration
or recharge. Regeneration is started at 2:00 a.m.
by the electronic timer (see page 13). It takes
place in 5 stages or cycles. These are:
FILL
BRINING
BRINE RINSE
BACKWASH
FAST RINSE

REGENERATION
DDFILL Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals
from the resin beads. To make the brine, water
flows into the salt storage area during the fill
stage as shown in FIG. 5. Fill cycle length
depends on how much soft water making
capacity you have used since the last regenera­
tion. It fills longer, the more water you have used,
and makes more brine. The greater amount of
brine cleans more hardness minerals from the
resin bed.
