    How many of you guys use a double DI to fill your tanks/barrels?

    I have a reading of 160ppm no if i was to use this set up using 2 11L vessels how many litters of pure would i get out of them before i need to replace the resin?

    Cheers

    It would take forever bud using a 100 gpd (american gallons running for 24 hours) so no good if you are on a water meter

    I do, was 110ppm (recently shot up to 160-70)through two 25L.
    I would guess you would produce 3500-4500L before a resin change is needed.

    At least a 450 gpd small ro but most would prefer to use a 4040 ro if on a water meter.

    I was buying a £72 25L bag of resin every 3 months.
    I would estimate you'll have to change your first DI vessel resin (which you swap position with second DI) every 5-6wks. I'd guess your annual resin cost would be less than £300 at your stated production.
