_..j_. SECTION 2 iii......iii_._ii.....I HOW YOUR WATER SOFTENER WORKS
B. 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 service water used between regen- erations,
-
The nozzle and venturi (FIG. 7) 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 miner- als 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. 9).
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.
