What is this copper line under the sink?
Today, the copper hot and cold water pipes terminate at shut-off valves under the sink, and flexible lines run between the shut-off valves and the sink’s faucets. The under-sink shut-off valves and flex lines makes servicing the sink fixtures easier because the water can be shut off right under the sink.

What causes pinhole leaks in copper plumbing?
The primary cause of pinhole leaks is the composition of the water flowing through your plumbing system. Hard water—high amounts of dissolved calcium and magnesium—or water that is too basic (low pH) or too acidic (high pH), can all contribute to copper pipe corrosion.
Can you fix a pinhole leak in a copper pipe?
Because pinhole leaks are small, the easiest repair method is to fill them with epoxy putty.

Should I worry about green copper pipes?
Patina, or the greenish colour that appears on copper pipes, happens from oxidation. Oxidation is common on copper when it is exposed to water and air over time. While this oxidized layer is not harmful, it does cause the copper to become corroded.
What is the white stuff on my copper pipes?
The visible white buildup is calcification from the minerals in hard water. Aside from looking ugly, this calcite will start to coat the inside of your pipes, which will restrict water flow and start to raise the pressure within the plumbing until it erupts into leaking.
Why are my cold water copper pipes black?
Black – If you see black copper, it may indicate the presence of high sulfur levels or other chemicals in the air, like sewer gas. It could also indicate that the pipe is coming into contact with other non-compatible metals, especially galvanized steel.
