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 the metal
flush valve into the open position for 2-3 minutes once a week.
Please ensure this valve is
CLOSED
when complete.
This valve is located on the drain line of the unit. This needs to be
opened when the unit is in the process of making water to allow the
water flowing through, to be re-directed back over the membrane.
All replacement filters and membranes can be purchased through
our website
Replacing your filters
–
(Filters only, not membrane)
Please have some towels and cloths ready, as some water will
escape from the unit.
Turn off the water by putting the isolator tap to ‘off’ position (1/4” turn
from on position) or using the garden tap.
Drain as much water from the unit as possible. If you have installed
the tap, open this for a few minutes. Then open the flush valve for a
few minutes, to release and built-up pressure.
*REMOVE THE MEMBRANE(S) FROM THE HOUSING AND SET
ASIDE UNTIL FILTERS HAVE BEEN CHANGED AND THE UNIT
FLUSHED*
Carefully remove the housing bowls and empty any residual water
down the sink / drain and remove of the exhausted filters.
Remove the wrapping of the new filter(s) and insert into housing(s).
Screw housing bowl back into place.
Repeat this for all filters contained in the housing bowls.
