I have copper pipes. The stain in my tub is blue ... not green, not green-blue, not aqua, but blue. Everything I've read seems to suggest copper corrosion, but I tested PH before and after the softener and it's consistantly 7.5.
Now the likely culprit is hydrogen peroxide. I have a peristaltic pump and inject H2O2 to fix my sulpher smell issue. The hydrogen peroxide is fantastic... no rotten eggs, and my excess iron drops out of suspension for easy filtration giving me water that smells great and doesn't taste like metal. However, it appears the peroxide is corroding my copper. My understanding is that that should not be happening... especially in non-acidic water. What gives? I'm injecting the peroxide at 25ppm with a mixing tank in the line. Is the copper/peroxide combination a no no or do I just need to reduce the h2o2 concentration?
As far as I'm concerned, no h2o2 isn't an option. I can't go back to rotten egg water. I would rather convert all my plumbing to pex. Side note: I also use Morton rust remover pellets. Could the citric acid be mixing with the peroxide to form something corrosive?
