Hi i bought a ionic DI filter cartridge 3 weeks ago but my TDS is still high 014 i also changed the pre filters . I plugged the DI filter straight in to the mains tap to see what it reads does any body know if this is normal by these figures . My TDS at the tap is 109 then after the DI it is 085 just wondering if i have a duff DI filter.
I did phone my supplier but he must be still on his dinner because he never rang me back lol
Tap TDS 109 to 115 then with just the DI plugged in i get 085
After pre filters and RO 015
Then after Di it drops to 014
Cheers Steve
