Gravity Water System Maintenance
New Assembly & Filter Replacement
Full System: Use a cleaning solution made of 5 mL (1 tsp) unscented chlorine bleach to 1 L (4 cups) of
water. Wash all plastic parts in cleaning solution. Rinse with clean tap water. Do not use cleaning
solution for the Ceramic Pre-Filter and 5-Stage Filter. Do not scrub plastic parts with coarse material like
scrub wool or steel wool.
Tap: Take apart the pieces of the tap and let them soak in cleaning solution while you prepare the filters.
Rinse with clean tap water. Install the tap.
Ceramic Pre-Filter: Soak the new Ceramic Pre-Filter in cool tap water for ten minutes. Do not use
cleaning solution or soap. Scrub the surface of the Ceramic Pre-Filter with cool water and a clean fine-
textured scrub sponge like the one included in the box. Install the pre-filter, making sure that 2 washers
are correctly placed inside and outside the upper tank and the nut is screwed securely (finger tight).
5-Stage Filter: Rinse the new 5-Stage Filter under cold running tap water until water coming from the
bottom of the filter runs clear; this should take about 3-5 minutes. Dry the outside of the 5-Stage Filter
with a clean paper towel. Screw the 5-Stage Filter into the Cartridge Connector. Install the Cartridge
Connector with 5-Stage Filter.
Mineral Stones: Remove stones from packaging. Boil stones for at least 1 minute to sanitize and
condition. Drain the stones and lay out on a clean paper towel or fabric towel to cool. Place stones into
the bottom tank. Note: Stones absorb odor. Do not use scented towels or towels with fabric conditioner.
Note: Water typically takes 2-4 hours to pass from the upper tank to the lower tank. When new,
however, the rate at which water passes through is slower; anywhere from 4-6 hours is typical the first
few times water is run through the system.
Weekly
Ceramic Pre-Filter: When the Ceramic Pre-Filter is noticeably dirty or running slow, scrub the surface of
the Pre-Filter with the grey sponge included in the box or another clean fine-textured sponge. Rinse
under running tap water. This may be once a week or as needed. Some water sources have more
sediment so more frequent cleaning may be required. The colour of a dirty Ceramic Pre-Filter depends
on the quality of the source water. Do not use soap or detergent.
