The Culligan
Process
Your Culligan water softener consists of three
basic components, (A) the Control Valve, (B) the
Mineral Tank, and (C) the Brine System.
A. The exclusive Culligan control valve
automatically performs a variety of tasks that
are necessary for the proper operation of
your water softener. These tasks, commonly
referred to as cycles or operating positions,
are Service, Regeneration, and Brine Refill.
1. Service:
While the control valve is in the
“Service cycle”, hard water is directed
down through the column of Cullex
®
resin
where hardness minerals are removed
from the water. The softened water
is then directed into your household
plumbing lines. The ability of the Cullex
resin to remove hardness minerals needs
to be periodically replenished; this is
referred to as Regeneration.
2. Regeneration:
While the control valve is in the “Regeneration cycle”, water is first directed up
through the column of Cullex resin to flush accumulated sediment out of the resin and down the
drain. Then, the regenerant brine solution is slowly drawn from the bottom of the salt storage
tank of the Brine System and is directed down through the column of Cullex resin, restoring the
ability of the resin to remove hardness minerals from your water supply. Once completed, the
regeneration cycle is followed by Brine Refill.
3. Brine Refill: While the control valve is in the “Brine Refill cycle”, a predetermined amount
of water is directed to the salt storage tank of the Brine System so that additional salt can be
dissolved to provide the brine solution that will be needed for the next regeneration cycle.
B. The Mineral Tank contains the Cullex resin column, Cullsan® underbedding, and an outlet manifold
(the Culligan Total Home also includes carbon media for chlorine taste & odor reduction). The number
of gallons of hard water that can be softened by the Cullex resin column before it needs regeneration
is called the “capacity” of the resin column, and depends upon the amount of hardness minerals
in each gallon of water (expressed as grains per gallon) and upon the amount of regenerant brine
solution (expressed as pounds of salt) passed through the resin column during regeneration.
Your Culligan service person, taking into account the hardness of your water and the amount of
softened water your household may reasonably expect to use each day, has carefully established
how often the softener will regenerate and how much salt will be used for each regeneration.
This will ensure that all of your soft water needs will be fulfilled without using an excessive amount of salt.
C. The Brine System consists of a salt storage container and hydraulic Dubl-Safe™ valve.
The salt storage container holds the salt that is used to make the regenerant brine solution.
The hydraulic Dubl-Safe valve limits the amount of water that is returned to the salt storage
tank during the brine refill cycle.
Since a predetermined amount of salt is dissolved with each brine refill cycle, the salt must be periodically
replenished in order to maintain efficient operation. Your Culligan service person will be able to tell you
about how often salt must be added to the salt storage container.
