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
theresin beads andthey aredischarged out the drain.
Howmuch brine is neededto clean theresin 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
ironminerals,dirt and sediments from the bed andto
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.
