Green colour inside copper pipes safe?

[GameForkStudio]

Hi all,

I have just changed my kitchen sink tap and this involved cutting the copper pipes under the sink. I noticed a green colour inside the pipes. When I wiped it with a tissue, the tissue became green.

Since this is the main house tap and we drink from it, I was wondering if the green colour was normal and is it getting into my drinking water?

Regards.

Very common - no issue - oxygen in the water reacting with copper. It is known as verdigris

not approve copper pipe for potable use of water and it seems copper pipe is safer than plastic muck from exchanges over the weekend
