2B. SOFT WATER SERVICE AND REGENERATION
r2-1BRINING: During brining, the brine is moved
from the sail 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 suctionto
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 sail
[]]BRINE RINSE: After all of the brine goes into
the resin tank, the brine valve closes. Water
keeps flowing the same way itdid during brining
except the brine flow has stopped. Hardness

drain. Brining and brine dnse together vary in
length relative to the fillcycle length.

mFAST RINSE: Backwash isfollowed by a fast
flow of water down through the resin tank. The
fast flow packs the resin bed and gets it ready for
retum 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 outthe hardness minerals.
Soft water goes to the house soft water pipes.

UP through the resin tank (FIG. 7) at afast rate to
flush iron minerals, dirt and sediments from the
bed and to the drain. The bed lifts and expands
for good cleaning.
