I Have a tmc v2 pure 50 3 stage unit with no d/I resin as yet ! The tds reading coming off the unit has always been around 2-3 ppm ! Yesterday I changed the micron pre-filter and the carbon 2nd filter and now I'm lucky to get a reading below 30 ppm ! I've back-flushed the unit and made sure everything is fitted correctly and I've even tried putting the old filters back in but I can't get the reading to come down ! Is there a bedding in period for new filters ??? Any help would be appreciated !
