Lucky you didn't get legionella. That is not up to spec, cold water lines should always be below 25°c. I have never seen such an installation, even in development countries it was done correctly.

Yikes, that's tough. In my city, the cold water pipes are buried close enough to the surface and the brutal sun that it comes out of the tap about 27-29c during the day.
