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. Control Valve
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
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
The Mineral Tank contains the Cullex resin column, Cullsan
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
The Brine System consists of a salt storage container and hydraulic Dubl-Safe
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�
Because 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�
