Section #7: Maintenance and Filter Changes
The WaterMark requires no maintenance other than annual filter changes. It is also recom-
mended that if you are going away for a few days to remove the 3rd filter from the unit and store
in the refrigerator in a Ziploc bag.
To change the filters on the WaterMark, remove the round chrome nut on top of the case and
lift the case cover off of the WaterMark.
You will see a filter wrench located next to the filters. Remove the wrench.
Be sure water supply is shot off and WaterMark is not holding pressure; to verify this, open the
WaterMark Faucet Spout or Accessory Faucet and allow any residual pressure to drain.
Take the filter wrench and remove the filter caps
by rotating counterclockwise. Lift the old filter
cartridge out and press the new cartridge
in. Filters 1, 3, and 4 will have a small cap
installed when they are packaged, make
sure you remove it before you install
them. Be sure to press the new car-
tridge completely into place and
replace the filter cap, then tighten
with the filter wrench. Tightness
level should be snug; do not over
tighten. Do this one filter at a
time to avoid placing filter car-
tridges and/or filter caps in the
wrong order.
Put filter wrench back in place,
replace the case cover, and re-
install round nut to hand tight.
All WaterMark filters will expire
and need to be replaced every 6
months, even if usage has been low.
The filters cannot last under water for
more than 6 months, at which point
they will actually start to release into the
water what they had once cleaned out.
