1) Air Bubbles: Lots of Air bubbles in cup or bottle when filling
It is quite normal to see air bubbles in a cup of pure water. This mainly occurs when a RO unit is first
installed or when filters are being replaced. When new filters are installed to the unit, the filter housings
are dry. When they are attached onto the RO head, air pockets will fill the housing. As water is turned on
and flows through the unit, the air pockets move throughout the system. This can have an effect on the
appearance of air bubbles in the water.
RO units will self purge the air bubbles that can accumulate inside the unit. As you continue to draw wa-
ter, trapped air will be removed by the water flow and you should quickly see a reduction in the bubbles
inside the water cup. You can also drain 1-2 tanks of water to quickly purge the air bubbles.
