304 Stainless and RODI

[afr0byte]

Does anyone know if there's enough leaching, from stainless in contact with RODI water for 12 hours or less, to worry about in terms of brewing? Reactivity charts would make me think it's ok....but...

It sounds like the effect would be EXTREMELY minimal:

0.02 mm of penetration per year

equivalent to 0.00002742857142857143 mm of penetration per 12 hours

I sincerely hope not!

Better safe than sorry

I'm definitely safe WRT all the parts of the RO system including the plumbing (plastic pipe) but I do let water sit in the HLT and/or mash tun over night without (so far) any sorry.

Cool, thanks for the reassurance. My porter is mashing as I type.
