PROBLEM:
The flow rate decreases even when the water valve is fully opened.
The filter cartridge should provide 1,000 gallons ( 3,785 liters ) of filtered water,
enough to supply a family of four with drinking and cooking water for a year.
However, filter cartridge replacement depends on the amount of water consumed
in your household and on the quality of your water supply. When the filter
cartridge is nearing the end of its lite expectancy, you may notice a drop in the
flow rate even with the water valve fully open.
Usually the slow flow rate will indicate that it is time to replace the cartridge.
Naturally occurring carbon dioxide or air leaking into the water supply. ( In rare
cases, the gas is naturally occurring hydrogen sulfide, indicated by a rotten egg
odor. )
as or air bubbles will not pass through the filler cartridge. Bleed the gas or air
from the system by depressing the vent screw located on the underside of the
base. Have a towel handy to absorb any water that might splash out of this vent
screw opening. When the flow rate is restored, you will need to periodically bleed
the gas or air from the system to maintain the proper flow rate.
High level of dirt or other particulates in the water supply.
Fill a clear glass with unfiltered water and allow to stand. If alter 10 minutes the
water remains cloudy, there is a high level of dirt in the water. This may be a
permanent condition or a temporary problem caused by heavy rains, repairs to
water mainlines, or the cleaning of municipal water mains, etc. You may have to
replace the filler cartridge.
TROUBLESHOOTIN
SOLUTION:
Cold water does not flow out of the filtration system.
There is an air bubble build - up in the system housing.
Air will not pass through the filter cartridge. Bleed the trapped air from the system
by depressing the vent valve on the base of the system ( see step 3 on page 3 or
step 3 on page 8 of the Start Up ( Instructions ) .
The saddle valve piercing needle has not pierced the cold water fine or the wing
nut has not been fully backed off to retract the piercing needle and open the
saddle valve.
Ensure that the copper pipe has been pierced and that the wing nut is backed off
completely to retract the piercing needle and open the saddle valve ( see steps 6
and 7 on page 7, To Connect to the Water Supply ) .
