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

theresinbeadsandtheyaredischargedoutthedrain.

Howmuchbrineisneededtocleantheresindepends

on:

--the amount of resin in the softener,

--how fast the brine goes through the bed.

The nozzle andventuri (FIG.6) makesuctiontotake

brinefromthe salt tankand putit intothe resintank.

Theykeep thebrine flowdown toa veryslowrateto

get the best resin cleaning with the least salt.

¢BRINE RINSE: Afterall ofthe brineis movedinto

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,dirtandsedimentsfromthebedandto

the drain. The bed lifts and expands for good

cleaning.

¤FAST RINSE:Backwash is followed byafastflow

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.
