It was my RO reservoir with a high level of zinc. When I did water changes it added zinc to my tank. It’s normal now. The float valve on my RO system had a big silver adjusting wing nut. It was leaching into my water.Zinc + copper = brassIdk why brass or if it actually is brass. It protrudes out of the other end too, not just the base. Maybe it’s an alloy of some sort. I have 4 on my tank and the only metal that’s been high on icp test was zinc. It was from my RO water float valve.




. I’m for sure ready for some delicious turkey
