BRINE RINSE: After a premeasured amount of brine is used, the brine valve closes. Water flow
continues as during brining, except for the brine draw. Tannin particles and brine are flushed from the resin tank to the drain.

through the resin tank at a fast rate to flush iron

AUTOMATIC BYPASS
During the brining, brine rinse and backwash
cycles of regeneration, unfiltered water goes
through the filter valve and to the house pipes, if a
faucet is opened. However, you should not use HOT water, if possible, because the water heater
will refill with unfiltered water.
