RO/DI,, filter questions

[Texreefer]

I have what I guess you would call a 5 stage unit..I have always had some trouble with too much pressure and the filter media deleting too quickly.. I am about to buy new filters for it and and want some Expert input on what might be happening.. I have the following,, a 1 micron prefilter( which i want to change to a 5 or 10 micron), a carbon block, then a GAC filter, then the RO then the DI,, I need the extra carbon because I am high in chlorine.
The pressure coming in is anywhere from 65 to 80psi.. generally stays right at 65
..
the following are my questions;
1. should I start with a 5 or 10 micron instead of the 1 micron?, and if I do this do I have to change any of the other filter types to compensate?
2. should I be looking for a 4:1 ratio of waste to product?
3. is 65 psi too much pressure and if so how do i reduce it? (it is not due to clogged filters)
4. New filter recomendations? any deals going on right now that I don't know about?
Thanks

Mike,

I'd drop a note to Russ.

On the chlorine subject; I added a corbon media cannister ahead of my water softner. I didnt do it for my fish tank. I did it cause I hate the smell and taste of chlorine in my drinking water.It also makes your water softner and rodi not have to work as hard. $500 well spent. I purchased a kinectico unit cause of the upflow feature. media lasts several years

All this sounds familiar. Did we talk on the phone this past week?

No, not me. I think you did reply about some of this in another thread though

Unless you have some specific reason to go with a larger pore size on your sediment filter I would stick with the 1 mic.

Are you using standard GAC? If so - that really has no place in your system - go with two blocks if you think you need it, but I suspect you do not.

65 PSI is good - would not think of that as "high." More pressure up to a max of 90 PSI would be even better.

Yes - you want a ratio somewhere near 4:1.

When you say you have been going through filters too quickly - do you mean the DI resin? What is your tap water TDS? RO TDS? DI TDS?
