How
Much Water Will My Water Softener Use?
This
is a very often asked question and does not have a simple
answer. Basically, we will produce a table of the different
sizes and brands of water softeners that we carry and support
with the average usage posted in the table, but a few words
about how we arrive at these data are in order.
The
table below will show the make, model and size of softener
along with the amount of water in US gallons that the softener
will use during regeneration. The information on injectors,
brine line flow control rates and drain line flow control
rates along with cycle durations which we use to determine
total gallons used, will come from the manufacturer's specification
sheets or service manuals. Water pressure is assumed to
be 60psi. It is important to keep in mind that these results
will vary a great deal depending on water pressure and temperature.
It is also noted that while the flow rate for a given cycle
is based on the duration of the cycle, not all cycles actually
require water flow throughout the entire cycle. For example,
the Fleck 5600 refill cycle is 24 minutes. The valve is
not refilling the brine tank for the entire 24 minutes.
The amount of water returned to the brine tank is dependent
on an adjustable cam lobe in the back of the controller.
There are numerous other factors that could alter these
results. This table is meant as a general comparison guide
only.

Cycle
times and injector flow rates for the Fleck model 7000 were
unavailable at the time of this writing. The injector flow
rates for the Autotrol models 255 and 268 were taken from
a 4 year old publication which may or may not apply to today's
Logix controlled systems. The older publication (Dealer
Operation, Installation manual) is all that is available
from the GE Water & Process Technologies web site.
