HOW YOUR WATER SOFTENER
WORKS
I
2B.
SOFT WATER SERVICE AND REGENERATION
[] BRINING:
Duringbrining,
the brine is moved
from
the salt storage
area,
into the resin
tank.
Inside
the
resin
tank,
brine
cleans
hardness
minerals
from
the
resin
beads
and
they
are
discharged
out the drain.
How
much
brine
is
needed
to clean the resin depends
on:
--the
amount
of resin in the softener,
--how
fast the brine
goes through
the bed.
The nozzle
and venturi
(FIG. 6) make suction
to
take brine from the salt tank
and put it into the
resin tank. They keep the brine
flow down
to a
very slow rate to get the best resin cleaning
with
the least salt.
[_BRINE
RINSE: After all of the brine goes into
the
resin
tank,
the brine
valve
closes.
Water
keeps
flowing
the
same
way
it did
during
brining
except
the
brine
flow
has
stopped.
Hardness
minerals
and
brine
flush
from
the
resin tank to the drain.
Brining
and brine
rinse
together
vary
in the length
of time they
take,
relative
to the fill cycle length.

[-_FAST RINSE: Backwash
is followed
by a fast
flow of water
down
through
the resin tank. The
fast flow packs the resin bed and gets it ready
for
return
to service
(FIG. 8).
After
fast rinse,
the softener
returns
to service.
Hard
water
goes into the resin
tank where
the
resin bed again takes out the hardness
minerals.
Soft water
goes to the house
soft water
pipes.

[] BACKWASH:
During
backwash,
water flows
UP through
the resin tank (FIG. 7) at a fast rate to
flush iron minerals,
dirt and sediments
from the
bed and to the drain.
The bed lifts and expands
for good
cleaning.
