SECTION 2 HOW YOUR WATER FILTER WORKS
C. FILTERED WATER SERVICE, AND BACKWASH
SERVICE
CLARIFIER FILTER
During service (Figure 6) water goes into the filter
and DOWN through the bed of mineral. The mineral
takes the dirt, sand, silt, clay and other sediments
out of the water and holds it in the bed. Clear, clean
water goes out of the filter and into the house pipes.
NEUTRALIZER FILTER
As low pH (acid) water flows DOWN through the
filter, neutralité mineral is slowly dissolved to raise
the pH. The neutralized or non-acid water then
flows into the house water pipes. Because the neu­
tralité does dissolve, you have to add new mineral
at least once each year, and sometimes more often
(see page 3-1).
TASTE AND ODOR FILTER
The taste and odor filter is filled with activated car­
bon. As water flows into and DOWN through the fil­
ter (Figure 6), the tastes and/or odors are adsorbed
and held by the carbon. Water without bad tastes or
odors goes into the house pipes.
When the activated carbon no longer takes the tastes
and/or odors out of the water, you must replace it
(see page 3- 3). The carbon usually lasts for up to one
year, and sometimes longer. It depends on how
much water you use, and how much taste and/or
odor is in the water.
BACKWASH
Backwash is a reverse or UPWARD fast flow of wa­
ter through the filter. The fast, upward flow flushes
dirt, sediment, iron, etc., from the mineral bed and
to the drain. The bed is lifted and expanded for good
cleaning. The bed is also mixed to remove any chan­
nels water flow may have formed through the min­
eral.
Following backwash, water again changes direction
to flow downward through the bed at a fast rate. The
mineral bed is repacked and prepared for return to
service.
