    I noticed at the bottom of the tank a kkind of yellow sand - which actually is resin coming from the unit

    Ive checked the DI cartridge - there are no filters I can replace - is just a perforated plastic

    It didn't happen since I bought the unit last year

    shall I just put a sock in the cartridge to prevent the resin going down the system ?


    regards

    what di have you got? is it one that has a 1lt refill in it? if it is then it should have a round sponge at the bottom of it then the resin, then the sponge then plastic perforated disc then lid

    has to be a fine sponge with not much gaps in. but that might work

    May I ask you for some more help pls - :(

    Firstly it's quite weird - but how on earth my ro/di unit worked fine without these sponges in the resin cartridge - for over 4 months I didn't noticed any resin in the tank until 10 days ago -- anyway , I crafted two round sponges from a kitchen sponge - seems ok now

    The most important question now is that the TDS reads more and more every day - even if the resin was changed a week ago ... It went up from 003 to 008 and I recon it will get even worse . May be I should replace the RO membrane ? (isn't too soon?! is about 5 months old)

    Or may be my kitchen sponge got moulded and now contaminates the water

    or may be the resin is not a good quality ? as I bought it on ebay not from pure freedom

    any help wd be appreciate

    thx

    are you flushing the system through before you go through the resin??

    my membraines are 2 years old.

    when my ro is running all the time the output before resin is around 012-014ppm but if i have it turned off for a few hours or a day the output comes out at 100+ppm

    it always need a good flush before eash time, mine has a 30sec boost flush with the pump and then i let it run for about 20 minutes before puting it through resin to make pure!

    Im gonna check the reading before the DI cartridge - to see what's coming from RO
