Water Heater Vent and Corrossion

I’ve never seen this texture on top of the water heater. Can someone let me know what exactly this is coming out from the water line locations. Also, is this vent (red circle) improperly fastened?

Thanks,
Mike

They are leaking, Mike. Also the vent pipe is not properly attached. Call out both in your report.
Good Luck!

Cause by a leak and or lack of proper dielectric fittings, resulting in Galvanic/Dissimilar metal corrosion.
When 2 different types of metal contact each other, the corrosion process is accelerated.
But I see water stains all over the top of that WH.

From here the vent pipe looks loose and improperly installed.

Like Joe said, both are defects that should be called out.

Thanks guys.
