I have a strange situation in my bathroom, all the copper water pipes

I can only assume that when the house was built(on concrete slab) the

today

You need to fix that.

I can not be bothered at the moment am not the slightest bit worried
that it is ever going to electrocute anyone, Some day I may jackhammer a
bit of concrete to expose some reo and bond it,
