Maintenance
It is highly recommended to change your filters periodically to
maintain the highest level of filtration from your RO system. Changing
your filters regularly can also prolong the life of your RO system. The
table (below) shows how often it is recommended to replace each
filter/stage in your system. This is dependent upon water quality;
water hardness & particulates may result in filters being changed
more regularly than shown:
3 Stage Units
–
You can upgrade your unit to a 4 Stage by purchasing the
media and chamber from our website.
RO Membrane Pressure Washing
–
When the RO membrane purifies the water, there are impurities and
bacteria left on the surface of the membrane which may affect the
quality and volume of the purified water. The RO membrane needs to
be cleaned periodically. Our units will flush the RO membrane
manually by turning ‘on’ the flush valve (L1 – see PIC 1) for 2-3
minutes once a week. Please ensure this valve is
CLOSED
when
complete.
