As the title says, anyone ever install a whole house reverse osmosis system themselves? 
The new house needs one (I knew that going in) because of salt in the well. There are currently at least 3 water treatment systems installed from someone trying to band aid the problem. I can buy the system and have it delivered, my thinking is remove everything that's currently there and just start fresh, but figured someone here might be a water expert with some ideas.

Do you want RO on demand? or can you store filtered water and use a smaller capacity RO?

A stored water system might also satisfy fire water storage requirements if needed?

Doesn't RO take too much out of the water and make it aggressive?

May require conditioning after filtering?

I -have- a whole house R/O system that was installed badly by the previous owner. I'm only familiar with repairing it as necessary.

I think Bearmtnmartin may have some information.

For what it's worth, our system goes: Well - pressure tank - sediment filter (p/o had plumbed it backward) - iron filter - three stage filter - dual R/O system plumbed in series - water tank.

I like to think all the pre-filtration keeps my R/O membrane alive longer.

There is a disconnected U/V sterlizer too but it's clearly been broken for a long time and I don't have any intention of bringing it online again.

It needs to be whole house as it's damaging appliances, faucets, etc. There will be a 500 gallon storage tank. From what I understand the conditioning is done before RO system. I have 3 quotes from $19k to $27k. The lower one is re using some of the current stuff, the higher one is not. I started thinking if they are removing everything and starting from scratch, can't I just do the same? I'll know it's done right, in the spot I wanted, and looks like about $9k in equipment. I'm not moving in for a few months, so not necessary to rush to install in a day.

In reply to ShawnG :

That's the correct order, I'd install the sterilizer because it's included. I'm leaning towards it so I'd understand it better vs just knowing what an installer told me.
