My drain goes out kitchen to rain barrel for garden use. Many people can hook up the unit in the laundry room and fill the washer with the waste water. You can fill jugs and use it to water plants. If you care enough, it's no big deal. It's as difficult as washing that tin can and going all the way across the kitchen to put it in the recycle bin.

SP it was a weird comparison but think of the concept behind it. For a reef tank that has $1000's of dollars invested in livestock you wouldn't want to cheap out and put something that could potentially kill that live stock. Same with a BMW or any luxury car, use of a higher end fuel reduces the chance of damage/ wear and tare on the unit. You do have a good point, people should be measuring there TDS before deciding what RO to purchase. In the end though a RO also removes chlorine and other impurities in the water that could be entering your system.
I would never put tap water in my tank, as it just spells hair algae for me :\.

That's fine if you can do that but not all of us have the ability to run a new water line outside and some of us have 8 months of below freezing winter. For indoor use you would have to setup a large storage tank with float and bypass system, then you would have to rig up some kind of way to use the stored water in things like laundry (but only the wash cycle not rinse). Reusing the waste water simply isn't always as practical as some of you make it out to be, 99% of the people using RO send the waste water down the drain and for good reason.

RO units are very wasteful and I don't believe you should use one unless you need to.

I'm not sure where Chilliwack gets their water from.. but here in Coquitlam (about 1 hour away from Chilliwack) I get 12ppm on ym TDS meter right from the tap. I just use a DI unit. Works for me and many other local reefers.
