Copper piping
Copper piping is a traditional metal piping used for water supply lines, known for durability and long life.
Why it matters
Copper is reliable and has a long track record. It requires soldering for connections and costs more than PEX.
Where people get this wrong
Copper can corrode in some water conditions. Pinhole leaks can develop over time. Galvanic corrosion can occur if copper touches dissimilar metals without proper fittings.
Real-world example
The home has original copper pipes from 1970. They still work, but a few pinholes have developed. Spot repairs are possible without replumbing the whole house.
Where this hits your build
This comes up during rough-in and final fixture installation. Accessibility for future repairs matters as much as the initial install.
