Over doing the RO/DI

[Spyd]

I agree. Puratek are nice units and they have everything you need all ready installed. I run 5 stages on my unit as I have added an extra di just because I had it kicking around. Can't beat the 1:1 good water to waste water ratio either.

I find my filters last for a good 6 months. I installed a chlorine / chloramine whole home filter and it is awesome!! No chlorine or chloramines in any of my household water and it lasts 6 - 7 years before I need to get the media replaced. It helps out my RO/DI unit big time as it has a lot less work to do and saves a lot of money in exhausting filters and membranes as well. Worth every penny!!!!
