2B. SOFT WATER SERVICE AND REGENERATION
F2qBRINING: 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 be&
The nozzle and venturi (FIG. 6) make suction to
take brine horn 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 sail
]-3qBRINE 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.
