This is not right.  The whole point of RO water is that it should be pretty 
free of dissolved solids.  Something is wrong.   Possibilities: bad 
membrane; waste set too low (to reduce waste water) so that output is not 
very clean; leak somewhere.   You need to check this out more.  Communicate 
with the person who sold you the RO unit.
