    Ive got a 25ltr DI currently, I want to buy a new one to run my water through the two to make the resin last longer, question is, what size should the second one be? Obviously the smaller ones are cheaper, but can you have a smaller one, say a 7ltr for the second DI?

    Get another 25L & it'll pay itself off within months.

    Also when you switch them a 7L will obviously not last long.

    It is true as the one with the more spent resin in it is still doing a job by bringing the ppm down.
