20 or 22 inch, I think.

You put the di vessel first, then the sediment filter second and then the r/o if my memory serves me. The sediment filter would then catch any carbon fines from going to the r/o membranes.

What membrane did they sell you Darran? They are much cheaper than the Axeon USA brand. Are they  Chinese manufactured ones?

that's how I set it up - carbon then sediment filter then RO

this is the one I went for

I had one of there membranes a few years ago and it performed very well, so I'm hopeful this will be the same
