    I think you mean an RO before the DI to save resin... DI polishing at wash flow will burn through it, always best to DI as slow as possible. Stretches your resin a lot further.
    Also if using V2 the onboard DI would clean that out, I guess so probably not worth it.

    no i don't need an ro, my tap is 36 & i use twin di to fill my tank, my tap is on full & i get 400 lts in about 30 mins but a few suppliers have said if i put my di vessels in the van after the pump then, because of a much slower flow through the resin it will last much longer, i buy resin every 4 months at the moment so even a bit would mean every 5 months.
    i have just half closed my tap to restrict the flow a bit but not long enough to tell.

    David K i only had backpacks for years, had a van mount for 1yr now & i love it but there are lots of jobs where a backpack is quicker, but you need a way to fast fill it, i have a separate tap in my tank which fills 22 ltrs in about 20 secs

    I hear that going slow is the way to go but my 'wssh flow' is only about 1L per minute anyhow. I'm sure there cant be a massive difference if I reduced that to 0.5L per min. Doubt it would double the life of the resins.

    Im sitting in my kitchen watching bottles fill from a tap, and I can say that having it slower than wash flow makes the resin last longer in bottles filled.
