Hi everyone. Ive been a WFP for 18 months now. I have changed the sediment and the carbon and the DI resin like I have done every 3-4 weeks when my TDS meter shows 005 (I dont like to work to 010). The RO system was changed a few months ago and the water going into the RO is reading approximately 30-33 on the TDS meter. I live in a very hard water area but I know ideally it should be 25 and under. After changing all the filters the TDS reading goes down to 000 ppm usually but last week, after changing all the filters, 2 days later the TDS reading was 005 so I changed the DI resin as only a couple of days earlier I changed the pre-filters. I got it down to 000 again but next day I checked the TDS and it was back up to 004. Any ideas please? (PS someone told me that the DI resin sometimes has to settle down but I've never had this problem before).
