from the salt storage area, into the resin tank.				SOFTENER IN BACKWASH
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.
￿BRINE 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.			￿FAST RINSE: Backwash is followed by a fast
Brining and brine rinse together vary in length of			flow of water down through the resin tank. The
time they take, relative to the fill cycle length.			fast flow packs the resin bed and gets it ready for
			return to service (FIG. 8).

WATER FLOW THROUGH THE SOFTENER IN BRINING AND BRINE RINSE

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.

FIG. 8 WATER FLOW THROUGH THE SOFTENER IN FAST RINSE

￿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.
