RO/DI unit upkeep

[mike31154]

I've recently acquired a RO/DI set up and also recommend this vice buying water. As far as maintenance & upkeep, there's not that much to it and after the initial purchase, the costs are your water source, occasional filter replacements, DI resin replacement and RO membrane replacement after a few years. A lot will depend on your source water with respect to output and filter replacement etc. I'm also thinking that up in Athabasca your source water will be pretty cold most of the year. RO membranes function better with somewhat warmer water. You don't want to hook it to your hot water system by any means, but if you can find some way to warm up the input to the RO, it will work more efficiently and faster as well.

You'll need storage containers and some way to dispose of the waste water. The waste can simply be sent down the drain, but I like to keep it for the garden etc.
