Why is my copper water line turning black?
Found in close proximity to basement sumps that collect water softener waste water (salt cleaning mixture). Cold water lines only. Homes have well water with some sulfur content in test samples. This is a chemical reaction. What I don’t know is if the reaction is damaging the integrity of the pipe and sweat joints.
What causes copper wire to turn green or black in an electric stove?
But overheated copper wires will form a dark-gray-to-black oxidation patina on the exposed wire surfaces, similar to what happens to an overheated copper pan on a stove. The overheating can be caused by excessive current in the wires or a lightning strike, and it will usually be accompanied by melted or discolored insulation near wire connections.
What causes a copper penny to turn black?
Copper turns black as a result of oxidation. This happens when there is a reaction between oxygen and moisture condensation, water or rain. When the oxygen that it contacting the penny dissolves, the oxidation occurs and leaves the black color. In marine, urban and industrial environments, copper tends to resist corrosion well.
What causes the copper in water pipes to turn red?
If there are iron pipes present, the water can be colored rust or reddish and contain metallic or sulfur odors and sediment. Corrosion can cause the piping to fail, sometimes in less than 10 years!
Why are my copper water pipes turning black?
The worst-case scenario for black copper water pipes is that the builder installed extremely cheap copper that contains a high amount of impurities. Over time, those impurities manifest themselves on the surface of the pipe. Does all copper pipe corrosion lead to pipe failure?

Where can I find black copper pipe in my basement?
Q. Black copper pipes. Found in close proximity to basement sumps that collect water softener waste water (salt cleaning mixture). Cold water lines only. Homes have well water with some sulfur content in test samples. This is a chemical reaction. What I don’t know is if the reaction is damaging the integrity of the pipe and sweat joints.
Why are the copper wires in my Pool Black?
At first glance I though the ground wires were insulated. On closer examination, there had all turned black. This was seen in both the service panel and the pool electrical panel. The copper in the inside panel was normal as was the copper on the air conditioner coils.
