SECTION 2 HOWYOURWATERSOFTENERWORKS
2B. SOFT WATER SERVICE AND REGENERATION
[-_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 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 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 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.

[_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.

[_]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.
