HOW YOUR WATER SOFTENER WORKS

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. 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.

[BBRINE 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).

[] BACKWASH: During backwash, water flows

UP through the resin tank (FIG. 7) 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.

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.
