HOW YOUR WATER SOFTENER WORKS
SECTION 2

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. 9) makes the
suction to take brine from the salt tank and put it
into the resin tank. It keeps 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.

£ BACKWASH: During backwash, water flows
UP through the resin tank (FIG. 10) 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. 11).
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.
