Thread: Blackened copper piping.

Hello All,

I need some input on today's inspection. Region is north east Indiana. My issue is the Hot water line coming from the water heater is blackened as far as I can see the piping that goes into the joist cavity. The room is approximately 6x10 unfinished and shares it with the furnace, grinder and sump pump, located in the basement with a dehumidifier (Temp 72 degrees - humidity 40-50% or so. The Cold water line is clean, both are dry. The pipe has a light film of black substance that came off on my glove. No apparent updates to the plumbing, seems all original (2006).

Thanks in advance!
Jeff
