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.
