SECTION 2 HOW YOUR WATER SOFTENER WORKS
B. SOFT WATER SERVICE and REGENERATION
REGENERATION
FILL: 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. 6. Fill cycle length depends on how much
soft water making capacity you have used since the
last regeneration. As you use more water, fill time
increases so more brine is made. The greater
amount of brine cleans more hardness minerals
from the resin bed.

BRINING: During brining, 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 hardness of your water,
- - the amount of water used during service,
- - the amount of resin in the softener,
- - how fast the brine goes through the bed.
The nozzle and venturi (FIG. 7) 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 is moved
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 miner­
als and brine flush from fhe resin tank to the drain.
Brining and brine rinse together vary in the length
of time they take, relative to the fill cycle length.

e 1 BACKWASH: During backwash, water flows
UP through the resin tank (FIG. 8) 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.
