Functional Description
Feed water enters the 5-micron pre-filter, which filters out suspended particles such as dirt or sediment. The filtered water
then enters the pre-carbon filter (3 sump models only), which contains granular activated carbon, which removes any
chlorine from the water.
The water then enters the reverse osmosis membrane. The membrane will allow only permeate (product water) to pass
through. The brine (waste water) goes to the drain.
Permeate then flows through a hydraulic shut-off valve to the storage tank. When the tank fills and the tank pressure
reaches approximately 2/3 of the inlet feed water pressure, the shut-off valve closes, which turns the system off.
When water is drawn from the faucet, permeate flows from the storage tank through the post carbon filter. This filter
contains granulated activated carbon, removing any taste and odor that has accumulated while stored in the tank. When
the tank empties, the shut-off valve opens, turning the unit on.
