so like hook up another say 3 prefilters mine its a
5M
Carbon

the membrane
DI

if i add 3 more it should look like
5M -

carbon,

Actually I wonder if there is something to that. Where he lives, is an established area, with older water mains. My area is fairly new.

It seemed like I would change the 5m pre filter at Mikes and a few days later it was dirty again.

The problem is you'll have to change the pre-filters quite often to lessen the impact on the RO.
