Why should I install copper piping?

Copper piping does not rust like galvanized iron piping and will provide safe clean water for years to come. The life expectancy of copper is the same as the building- meaning install it once and forget about it. Galvanized iron pipe has a thirty year life expectancy. Plastic or PEX will be legal August 1, 2009 and might prove to be a cheaper alternative to galvanized and copper piping.
