We just moved into a newly built condo and found this next to the water heater.

The pipes can’t be more than a year old but they were wrapped with insulation.

Is this a problem? What would cause this to a pipe less than a year old installed?

thank you

It's not corrosion? The flux used during soldering remains and it accelerates surface oxidation. Just clean it up with a 3M scrub pad and wipe it down with a little alcohol. You can use a wet SOS pad and it'll polish the metal. Next rub on a very thin coat os light oil like 3 and 1 household oil to minimize further oxidation. Do not use vegetable oil.

Thank you. So to be clear, it's not from a leak? I can just have it cleaned off and not worry about this leaking hot water in the water heater closet?

This was installed two years ago.

Thanks

Your picture isn't showing the entirety of the pipe and the source of that white trail from up top. There is No way for us to verify that what you see is not caused by a leak or was from flux. More information would be needed to get a better idea of where that is coming from. Most likely its as Wayne suggested, but can't be confirmed. Leaks in copper can self seal if minerals in the water are deposited as the hot water evaporates.

The downside to copper vs an Uponor fitting is that you can't see beyond the surface of the copper fitting to see if its done correctly while you can see the entirety of a Uponor expanded fitting through the opaque collars.

Hey, wait a minute.

This is awkward, but...
