lol I'll only be doing like 5 g at a time as the thing hooks to the SINK
LOL jebus... that was bad

Kent carbon has had a known issue, I believe it was releasing everything back into the water column. If you use it I would highly consider switching brands. Alot of LFS refuse to carry sell or even look at it.

yup high copper content and arsenic in some batches

still make sure you have something to switch it off, I flooded my kitchen many times making 5 gls of water, even with setting the timer on the stove...mine is in the basement now, only had 1 incident since moving it down but at least it won't cause any damage now...:redface:

and thanks for the correction, that could have been an awkward vision.....

:lol: STUPID PHONE!

I don't know if it's possible for you or not, but I installed a bulkhead at the top of my RO/DI storage container with a PVC hose going to a floor drain. I definitely did not do this because I forgot to turn off the unit a few times!

Not to go off on a tangent but mineral water is not tap water! Mineral water is good, it's basically filtered tap water and remineralized or from a pure source. Tap water may contain good minerals but it contains far more contaminants that are not healthy at all. So before you freaking out about how rats urinated more from a water drinking study and how important it is to obtain that 0.0005% daily intake of calcium from water consider the following.

• Tens of thousands of chemicals are used, only a few dozen are actually tested and regulated by water treatment.
• Both government and independent scientists have linked even low levels of hundreds of legal contaminants in tap water to cancer, reproductive difficulties, and other diseases. There are more than 2100 known drinking water contaminants that may be present in tap water, including several known poisons.
• Drinking water regulations are out of date, many treatment plants were built decades ago to remove only harmful bacteria and nothing else.
• Pharmaceuticals have been found in the tap water, water treatment plants are not currently required to test for pharmaceuticals.
• Studies in some areas of Canada have shown high lead content in tap water, lead can increase the risk of learning disorders in small children.
• Every year, 18 billion pounds of new pollutants and chemicals are released into the atmosphere, soil, and groundwater.
• The only way to ensure pure, contaminant-free drinking water is through the use of a point-of-use filtration system such as an RO unit.

If you're worried about mineral content, take a multivitamin. Personally if you have RO water in your house I think you'd be a fool not to drink it. DI may be a separate issue but not something I worry about but those who do can simply tap in before the DI filter to access RO water for drinking purposes.

a well written post, but for for others reading, and as a student of toxicology, risk assessment and evaluation I gotta ask, are you suggesting tap water is not safe to drink?

i use RO water for my coffee, RO/DI for my aquarium and drink tap water...

What is safe to sum may not be safe to others, and water in some places is much better than others. Just sharing what I know and trying to clarify a few things. We can each make out own decisions on what we deem safe or best for us. For me it's not about whats safe, just what I believe a better option. My main point of that tangent was really to clarify differences between mineral water and tap water.

Sphelps is east of Calgary. The water east of the city is in very bad shape, and there are loads of pollutants in it that the treatment plants don't remove (according to a friend of mine who works for the government testing water). While his reaction to tap water may seem a bit extreme, it is understandable (I would feel the same way if I were east of here).
