The Culligan
Process

Your Culligan water conditioner 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 conditioner. These tasks, commonly referred to as cycles
or operating positions, are Service, Regeneration, and Brine Refill.
Service: While the control valve is in the "Service cycle", hard water is directed down
1.
through the column of Cullex
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 . . .
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 . . .
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
manifold. 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
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.
