They're food grade pails bought new from a plastics store here in the city. Not old salt pails. It was unacceptable to me as well that's why I didn't use it. However I don't like wasting all the water. So if the few ppm come after the 0tds water goes from my res into the mixing pails, it has to be some kind of residual from my mixing & obviously not perfect cleaning. So I'm not going to worry about it anymore, as long as the water coming out of the R/O Di. reads 000TDS.
