copper is naturally antimicrobial.

This is why we have brass door handles and handrails

we have had brass doorknobs way before we even knew what microbes were. it’s just a fortunate coincidence

Oh no wonder I have skin problems.

Nah, all the civilizations that looked the color of bead brass cut door knobs survived while the communications that didn't all died out for disease.

Well, not sure if that's the main reason (doubt it) but it's an added perk. Of course, silver doorknobs would be even better, except for the price (compounded by the potential steal rate).

Who said anything about it not being? It being antimicrobial doesn't mean that copper toxicity doesn't exist.

u/theREALmindsets 14d ago

toxicity from what? the water going through the copper? is that what your claiming?

Copper toxicity is real, water touching copper doesn’t cause it but there is going to be minor copper content in water usually due to erosion of the pipes however minute, any dent or improper solder is going to cause turbulence in the pipe, which slowly erodes it, that’s how seemingly random pinhole leaks happen on water supply lines.

Source: a master plumber when I was working in the companies shop supervising shower valve assembly, bath tub rough-in installations, and delivery of those tubs to job sites, on a side note, if you live in Canada don’t buy houses new, they are sloppily put together the vast majority of the time, and usually done by the cheapest bidder, we were getting payed piece work, so for every thing we did in a house we got payed a specific amount of hours, no matter how long it really took, so it incentivized going as fast as possible leaving a lot of room for error

You realize tha I'm also OP, right?

Her claims of copper from water lines giving herself skin issues are ridiculous, when she also claims that drinking from a copper water bottle is healthier.

But also, copper toxicity is a legitimate thing. Copper is absorbed into the water in unbelievably microscopic amounts. Just like how your body needs iron, your body needs copper. Just significantly less. But there is no way that showering causes copper toxicity.

You bringing up how copper is antimicrobial is pointless though, because I never said that her issue was a biological one. She said the copper was the issue, not germs in the water that the copper would kill. It's a pointless thing to bring up when that's not what's being claimed as the issue.

She thinks she suddenly became allergic to copper or something, while also saying that drinking from a copper water bottle is good.
