ro/di unit
 

looking at getting one of these units has ne 1 else bought one of these?? comments concerns things to look for in ro /di units would also be appreaceated also are the replacement cartrages redaly available and are they a standard size

looking at this on ebay http://cgi.ebay.ca/AQUA-SAFE-100GPD-...QQcmdZViewItem

seach aqua safe, there is a ton of info here on them.

pick up some extra filters from ed, when you purchase your unit and you can save on extra shipping costs.
i bought my units 6 months ago, and just picked up a case of the "21 replacement filters" from aquasafe

I have one and it does work good...and I would buy another if this one crapped out. I bought extra filters when I bought mine cuz I am one to put things off if I don't have the parts....NOW. :biggrin: Just ask my wife :mrgreen:

how much water is wasted from these units?

I think about 3 times as much water is wasted as is made... and that is something common to RO units. It is still good water though, just has higher disolved solids. I water the plants with mine. :smile:
