Hello,
I've got a strange issue where my well water becomes corrosive if I treat it with either Chlorine or peroxide. I inject enough to get a residual (.5ppm-1ppm chlorine or 4ppm+ for peroxide). The residual is then removed via 2 cubic feet of catalytic carbon. The water ph is around 7.3 and doesn't change much pre vs post treatment.
My home is mostly PEX with the exception of the stub outs and the hot water heater hook up. Cold water is fine but I'm getting dissolved copper on the hot water side. I see around 500ppb on the first draw as well is visible discoloration of the water. If I bypass the chemical injection and cycle the water in the hot water heater, I get very little to no dissolved copper on the hot side.
1. Any idea why pre-treating the water with chlorine or peroxide increases corrosivity even after the residual is removed via catalytic carbon? Does chlorine/peroxide increase the amount of dissolved oxygen in water?
2. I may have to forgo chlorine/peroxide altogether. My AIO catalytic carbon system can remove the sulfur smell (6ppm), but the sulfur bacteria seem to re-establish itself in the house plumbing after some weeks. Would UV treatment be a viable option? Ex: the iSpring UVF55 12 GPM or similar.
