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 exclusive Tripl-Hull
™
an outlet manifold. Note: The Mineral Tank of Aqua-Sensor
device that determines when the Cullex resin needs regeneration. 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 serviceperson, 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.
