3. Expired Filters
4. Mixed Up Drain Line and
Drinking Line
2. Alkaline filters will naturally
increase the TDS of the water,
especially when new. If you have
low TDS water already, it is
possible for the TDS level out of
the alkaline filter to be higher
than your inlet water. This is
because you are adding minerals
back into the water therefore
increasing the TDS and alkalinity.
3. If the filters have not been
changed as per the
recommendations, it is likely that
the increased TDS is due to the
filters needing replacing.
4. This is common as sometimes
the lines may be mixed up. Make
sure that the tubing connected to
the ‘Drain Line’ flow restrictor is
being run to waste, do not use
this water for drinking. Your
drinking water line should be
marked with either ‘outlet’,
‘Drinking Water’ or ‘Aquarium
Water’.
Hot Water has been run through
the filter
Reverse Osmosis units are
designed for cold water only. If
you accidentally run hot water
through the membrane for a
short period of time, it may still
undamaged. What will happen in
the pore size in the membrane
will expand and allow more
contamination through. Run the
unit on cold water for 15 minutes
and test to make sure there is no
issues.
