My RODI unit had a dual inline TDS meter attached. If I am using it correctly the water going "in" would be the tap water and it reads 7. The water going "out" would be the RODI and it reads 0. I think that alleviates my water as the source of the problem. I'm leaning toward the brute as the source. Do y'all think it will eventually stop leaching silicates or do you recommend a different container for mixing water?
