where to get RO/DI water?

[scherzo]

I'd also suggest getting a TDS meter. Much better at figuring out if you need to change your cartridge or not.

Also, from a water conservation standpoint. I like the DI unit because it doesn't produce any waste water. We have very low TDS so I'm sticking to my DI for a while. I've actually budgeted for a BRS RO/DI unit but I'm still deciding if I want to create waste water that just gets dumped... it makes me feel bad..

I get a TDS as low as 8ppm.. most days it is about 14 or 15. I'm about 2 kms from the Coquitlam watershed so I'm lucky that way...
