Ive got a purefreedom system 650l with ro and ive added a softner to it, My tds has just gone upto 001 after resin so going to change all, do i add salt, run water through softner till salt has disolved then open up the ro and run through both filters and ro (if so for how long). once done do I disconnect the hose thats connected to resin and run through and wait till tds is down to a low reading then add hoselock to resin (my system is resin before tank so sits in tank at ooo). How do i change the resin is it a case of emtying cannister washing out and filling. Can someone give me a run through as how to do it.
