Hey guys so I'm looking to buy large food grade water containers to contain RO water without contaminating it. Homedepot sells a colaspable 400L one by does not indicate if it's food safe or not. I need one or two containers to add up to about 80gal. Here's link for the colapable version if anyone is able to find info on it.
