USING THE PRESSURE GAUGE:
The pressure gauge is used to monitor the condition of the Sediment
and Carbon Prefilters. With the Sediment and Carbon filters removed, the
gauge will indicate the “actual” tap water input pressure. When the prefilters
are “new”, the pressure shown on the gauge will be slightly less than the
actual tap water pressure and as the filters age, the pressure will drop
due to the dirt that will collect in the prefilters. When the pressure on the
gauge drops below 40 PSI or as the filters collect particulates and the
pressure drop is greater than 15% to 20% of the normal water pressure,
the prefilters are in need of replacement.
NOTE: When the pressure on the pressure gauge drops below the normal
readings; do not “assume” that the sediment filter is the only cause. In some
geographical areas where the input water contains a high percentage
of very small micron particulates, the carbon filter may become clogged
before the sediment filter. (The filters may look “new” but still cause the
water pressure to drop). Do not judge the condition of the prefilters by
their color, always use the pressure gauge to determine the condition of
the prefilters.
