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.
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 . . .
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
®
underbedding, and an outlet
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
™
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.
